The 2025 Audi Q7 went on sale for RMB 609.8-804.8 million.

A few days ago, the 2025 Audi Q7 was officially launched, and the new car launched five models with a price range of 609.8-804.8 million yuan. As an annual modified model, it mainly adjusts the vehicle configuration, and other changes are not significant.

The appearance of the new car remains the same as that of the current model, equipped with the iconic Q family octagonal grille, and designed with a large honeycomb mesh single frame grille. The new car comes standard with matrix LED headlights, and the lighting effect is even better. In terms of car colors, nine car body colors are available: Sakil Gold, Istanbul Red, askari Blue, Waitomo Blue, Kara Labai, Tianyun Grey, Legend Black, Glacier White and Satellite Silver.

In terms of models, the new Audi Q7 cancelled the 45TFSI S line sports model and added the 55TFSI S line Darth Vader version, which has a unique black appearance kit and red calipers. In terms of configuration, the Darth Vader version is upgraded with functions such as front seat ventilation, adaptive cruise, lane change assistance and active lane keeping.

In terms of power, the new Audi Q7 uses the 2.0T engine of the fourth generation EA888 and the 3.0T V6 engine of EA839 +48V. Their maximum horsepower is 265 and 340 horsepower respectively, and their peak torque is 370 Nm and 500 Nm. The transmission system is matched with an 8-speed Tiptronic transmission.

Commemorating the 105th anniversary of Comrade Qian Xuesen’s birth: All for the strength of the motherland.

  editorial comment/note

  2016 is the 105th anniversary of the birth of Comrade Qian Xuesen, a "National Outstanding Contribution Scientist". As an outstanding scientist and thinker, Qian Xuesen is not only the "two bombs and one satellite" founder of China, but also has made great achievements in the space industry, and initiated the "China School" of systems engineering, which is unique and stands tall compared with foreign counterparts. On April 24, 2016, when China’s first space day is coming, it is particularly necessary to commemorate Qian Xuesen and explore the driving force of innovation from his long-term practical experience in major engineering and colorful artistic thinking.

  Create an immortal space monument

  Some people say that a great man and a master come out once in hundreds or even thousands of years. As an outstanding scientist and thinker, Qian Xuesen is really a great master. Facing the needs of the country, Qian Xuesen has made five major choices in his life, and made irreplaceable contributions to the world anti-fascist war during his stay in the United States. As the founder of China’s "two bombs and one satellite", his great achievements in the aerospace industry are a monument in the rejuvenation of the Chinese nation, and the idea of system engineering and general design department he pursued all his life has promoted the development of human science and technology. Compared with foreign counterparts, China School of Systems Engineering initiated by Qian Xuesen is unique and stands tall. All these are inseparable from Qian Xuesen’s firm Marxist belief, solid theoretical foundation, rich scientific and technical knowledge, long-term practical experience in major projects and colorful artistic thinking. Today, the trend of world multipolarization and economic globalization is deepening, and the information society is developing rapidly. We feel the brilliance of Qian Xuesen’s philosophy more and more, and see the strong vitality of system engineering.

  Qian Xuesen always combined his personal ideal with the destiny of the motherland, and he transferred from railway engineering to aviation engineering interdisciplinary; Cross-regional travel from China to the United States to study; Transfer aviation theory from aviation engineering across disciplines; Cross-domain entry into new and cutting-edge fields such as rockets, missiles and engineering control. These rich experiences enabled him to gradually improve his ideological system in the process of continuous integration and transformation, laying the foundation for presiding over China’s space industry.

  Qian Xuesen shoulders a special mission in the struggle of the space industry. He is both a planner and an implementer. He is both a leader and a teacher. He led the astronauts to make the impossible possible, shaping another milestone in his life, and it was China’s space industry that provided a practical soil for Qian Xuesen’s system engineering thought. As Yu Jingyuan, a researcher at the former 710 Institute of Space, said: "Qian Xuesen pioneered China’s space industry, but also created a set of systems engineering management methods and technologies with both China characteristics and universal scientific significance."

  Qian Xuesen applied the method of "large-scale corps fighting" of the People’s Liberation Army to the construction of national defense projects, and applied the unique democratic centralism of our party to the whole process of development, uniting all the forces that can be United to use in the cause of "two bombs and one satellite", and finally achieved success. Qian Xuesen realized that in order to engage in cutting-edge national defense technology and command such a large social labor, it is necessary to set up a department composed of high-tech scientific and technological teams with many disciplines, complete specialties and rich research experience to provide technical staff for leaders. This department is the embryonic form of the current aerospace system general design department, where an interactive and flexible management model combining unified leadership and two command and support systems has been realized.

  In February 1962, with the approval of Marshal Nie Rongzhen, the Science and Technology Committee of the Fifth Research Institute of the Ministry of National Defense was established, with Qian Xuesen as its chairman. The establishment of the science and technology commission has enabled the party and government leaders to be alert and clear-sighted, and has an effective way to make scientific and democratic decisions. The organization form of the Science and Technology Committee has been used up to now. Not only the national defense science and technology industry system, the military scientific research and experimental units, but also government departments and companies have gradually established this organization.

  In the late 1970s, Qian Xuesen once again returned to academic theoretical research. On the basis of in-depth summary and refinement of early space career practice, he published "The Technology of Organization and Management — — System Engineering, for the first time, clearly defined the early understanding of China’s system engineering, and system engineering began to develop rapidly in China. In order to further develop systematics, with Qian Xuesen’s personal initiative and participation, a seminar on systematics has been held in 710 Institute of the former Ministry of Aeronautics and Astronautics since 1986 (it was resumed in China Institute of Aerospace Systems Science and Engineering in 2013), and a "comprehensive integration method from qualitative to quantitative" and its realization form "comprehensive integration seminar hall system from qualitative to quantitative" have been creatively put forward, which is a concrete embodiment of Qian Xuesen’s system engineering thought in methodology. The holding of the seminar has made a solid contribution to the development of systems engineering in China. It is known as the "cradle of systems engineering in China" and shoulders the banner of systems engineering in China.

  System engineering serves the country.

  Qian Xuesen’s process of pioneering and establishing system science and system engineering has always been closely linked with China’s socialist modernization and the development of science and technology at home and abroad, and focused on solving major problems that some countries must solve. Therefore, Qian Xuesen’s system engineering thought not only has important theoretical innovation, but also has extremely important practical guiding significance and has made great contributions to national construction.

  Qian Xuesen deeply felt that the overall design department played an important role in China’s "two bombs and one satellite" to achieve remarkable achievements, win glory for the country and compete for the people. Therefore, on the basis of in-depth study of the social system, Qian Xuesen combined with his extremely successful experience in the development of "two bombs and one satellite" and put forward the proposal of establishing the overall design department of the national economy in 1979 according to the design principles of system engineering. By using the method of system engineering, he comprehensively analyzed the system structure of China’s socialist construction, namely, "the construction of socialist political civilization, including democratic construction, institutional construction and legal construction; The construction of socialist material civilization, including economic construction and people’s physical construction; Socialist spiritual civilization construction, including ideological construction and cultural construction; Socialist geographical construction includes environmental protection, ecological construction and infrastructure construction. " China’s socialist construction is an open and complex giant system, which should focus on economic construction and make all aspects develop in harmony, cooperate with each other and promote each other. To this end, Qian Xuesen proposed to set up a general design department specializing in socialist construction to carry out top-level design of national construction, which was highly valued by the party and state leaders and organized special discussions. Although this proposal was not finally realized before Qian Xuesen’s death, in the new historical period, an important responsibility of the central government to set up a comprehensive deepening reform leading group is to be responsible for the overall design of the reform.

  In June 1984, Qian Xuesen put forward the idea of developing agricultural knowledge-intensive industries by using system engineering thought and modern science and technology. Its main connotation is "based on grassland, making use of sunlight and creating wealth through biology". It is a new industry that uses systematic thinking, overall concept, scientific and technological achievements, industrial chain, market operation and cultural docking to manage desert resources, realize a virtuous cycle of "greening the desert, increasing farmers’ income and increasing enterprises’ efficiency", and link "blood transfusion" with "hematopoiesis" to create a great 21st century. Under the guidance of Qian Xuesen’s theories, Inner Mongolia has gradually formed sand industry series such as licorice, seabuckthorn and cistanche deserticola, and grass industry series such as cashmere, meat, milk, medicine and potato. On January 19th, 2008, when Comrade Hu Jintao visited Qian Xuesen, he said, "Not long ago, I visited Erdos City, Inner Mongolia Autonomous Region, and saw that the sand industry there developed very well. The processing of psammophytes has been started, the ecology is being restored, and the people’s living standards have also been significantly improved. Qian Lao, your idea has been realized. "

  Qian Xuesen’s research in his last 30 years has applied the system engineering thought to China’s social system, such as military field, social governance, ecological environment and transportation. Now, the inheritors of Qian Xuesen’s thought have extended it to all aspects of our country’s construction and become its important guiding ideology.

  Learn lively and make good use of it to enrich philosophy.

  Qian Xuesen’s love for national conditions and people’s hearts strengthened his belief in Marxism. He always thinks that Marxist philosophy is the source of wisdom and scientific truth. In his letter to his friends, he said: "A Marxist will never love the people and will never be unpatriotic." "A Chinese Communist party member must adhere to Marxism–Leninism and Mao Zedong Thought, which is ‘ Persistence ’ Is correct. "

  Qian Xuesen not only used Marxist philosophy to guide research, but also treated himself with historical materialism. He believes that missile space flight is a cause of thousands of people, and no one can do it without the leadership of the party and collective efforts. He just came back to the motherland at the right time and did what he should do. He is only one thousandth, one thousandth of this collective under the leadership of the party.

  Qian Xuesen always tries to guide scientific research and engineering practice with Marxist philosophy. He believes that the rapid development of science and technology has enriched and deepened Marxist philosophy in the more than 100 years since Marx and Engels laid the foundation for the establishment and improvement of Marxist philosophy system, and Marxist philosophy is in a guiding position for scientific development. In his "Methodological Problems in Technical Science" published in 1957, he wrote: "In the research of technical science, we should combine theory with practice flexibly and not act rigidly. I think this flexible combination of theory and practice is the essence of dialectical materialism. "

  In the process of studying and practicing Marxist philosophy, Qian Xuesen realized the combination of science and philosophy, demonstrated the scientific nature of Marxist philosophy with the achievements of modern natural science, and enriched the scientific connotation of Marxist philosophy. At the same time, from a philosophical perspective, he pointed out that the prospects of some major scientific and technological developments will have an impact on human society. His scientific theory embodies dialectical philosophical thinking, and his philosophical thinking has profound scientific connotation.

  His scientific outlook and methodology not only absorbed the essence of China’s traditional culture and the most advanced scientific and technological achievements in the contemporary world, but also condensed a deep patriotic enthusiasm and a high sense of social responsibility, all for the strength of the motherland, world peace and people’s happiness. He attributed all his achievements to the party and the collective. At the conference that the State Council and the Central Military Commission awarded Qian Xuesen the honorary title of "National Outstanding Contribution Scientist" in October 1991, he said: "I think today’s science and technology is not only natural science engineering technology, but also the whole knowledge system for people to understand and transform the objective world. The highest summary of this system is Marxist philosophy. We can completely establish a scientific system and use it to solve problems in our socialist construction. " And stressed: "I want to promote this for the rest of my life."

  Qian Xuesen’s spirit shines forever

  From the Marxist point of view, Qian Xuesen highly summarized the development of science and technology and its great role in promoting social development, and pointed out the differences between scientific revolution, technological revolution, industrial revolution and social development, as well as their mutual connection and interaction. He believed that they were in a network and feedback relationship, and summarized the law of social development as: "Scientific revolution comes first, then leads to technological revolution, and finally industrial revolution", and industrial revolution caused a leap in social form. Qian Xuesen’s exposition on the interrelation and interaction between the four revolutions and their influence on social development enriches Marx’s viewpoint that "science and technology are revolutionary forces to promote social development".

  In the mid-1980s, theories such as "post-industrial society", "the third wave society" and "information society" came out one after another. Qian Xuesen believes that these new things and situations need to be analyzed, generalized and summarized by Marxist philosophy, and the concept of Marxist social form should be developed. The fifth industrial revolution with global information network and multimedia technology has brought people into a brand-new era. This is "due to the promotion of the fifth industrial revolution, the development of market economy in the world, the trend of economic globalization is increasing day by day, and the world is gradually forming an interconnected big society, and no country can close its doors." And the invention of electronic computer has produced a new industry — — Information industry, which not only changed the traditional production tools and production relations, but also created people — The spiritual productivity of the combination of machine and machine. Qian Xuesen predicted that the information revolution will eventually lead to the elimination of the difference between physical and mental work from the perspective that electronic computers are tools to liberate mental work, and this prediction has been realized.

  According to the latest progress of biological science and technology, Qian Xuesen put forward the "Sixth Industrial Revolution" in 1984, which is a great agricultural revolution with modern biotechnology as the core. By the 21st century, it will develop into a bioengineering industry with animal and plant engineering, drugs and vaccines, protein project, cell fusion and gene recombination. In his view, the Great Agricultural Revolution was caused by the industrialization of modern biotechnology. In essence, it used solar energy as energy, used biology, water and atmosphere, and formed a new knowledge-intensive industry through agriculture, forestry, grass, livestock, poultry, fungi, medicine and fish, plus industry and trade. The large-scale agriculture developed in this way, except for the different products produced, has no substantial difference with industry in production mode, and its development may eventually lead to the elimination of the differences between industry and agriculture, urban and rural areas.

  Today, many of Qian Xuesen’s foresighted theories and viewpoints have come true. He is like a giant who travels through time and space. The longer he takes, the more he can appreciate the significance of his thoughts to the greatness of mankind. As time goes by, we feel the dazzling light of Qian Xuesen’s wisdom.

  At present, the world economy is in the process of deep adjustment, the recovery momentum is insufficient, the geopolitical influence is aggravated, and uncertainties are increasing. The domestic reform has entered the critical period and deep water area, and the contradictions in all aspects have become increasingly prominent. We must pay more attention to the systematicness, integrity and synergy of the reform. The Third Plenary Session of the 18th CPC Central Committee made a general plan for comprehensively deepening the reform, and put forward specific reform objectives in economic, political, cultural, social, ecological civilization, national defense and army building, and opening to the outside world. Deepening the reform in an all-round way and building a well-off society in an all-round way are all complex systems engineering. Escorting the China with the idea of systems engineering will help it run more stably, faster and further.

  Infinite loyalty to the party and great love for the motherland are the core elements and outstanding portrayal of Qian Xuesen’s patriotic feelings. Qian Xuesen always combined his personal ideal with the destiny of the motherland all his life. During his school days, he was diligent and diligent, aiming at serving the country and establishing the lofty ideal of saving the country by aviation; During his stay in the United States, he devoted himself to studying, aiming at rejuvenating the country and returning to China to serve; After a difficult return to China, he devoted himself to national defense, aiming at strengthening the country and achieving the great cause of "two bombs and one satellite"; In his later years, he was old and eager to enrich the country and devote his mind to people’s happiness. In his later years, Qian Xuesen once recalled: "Why should I take the road of returning to the motherland? I think the reason is simple — — For nearly a hundred years since the Opium War, Chinese people have been dreaming of becoming a powerful country and fighting constantly. Revolutionary martyrs sacrificed their precious lives for the sake of rejuvenating the country and the dream of strengthening the country for the descendants of the Chinese people, and their blood flooded the land of China. Personally, as a member of the Chinese people, I can only follow the footsteps of the martyrs and explore and pursue in thousands of dangers, regardless of others. "

Report on the Development Trend of Agriculture and Rural Areas in China in 2022-Ensuring Priority Development of Agriculture and Rural Areas (11th Edition of Economic Daily on January 21st)

  Under the background of stable macroeconomic operation, China’s agricultural and rural reform and development have achieved remarkable results, and the role of agriculture as a ballast stone for economic and social development has become increasingly significant. This report reviews the development of China’s agriculture and rural areas in 2021, analyzes the important opportunities and challenges faced in 2022, and predicts its development trend. On this basis, it puts forward relevant countermeasures and suggestions based on the hot issues that need attention in the process of agricultural and rural economic and social development.

  Agriculture grew steadily and grain reached a new high.

  2021 is the first year of the "14th Five-Year Plan". China has overcome the adverse effects of the COVID-19 epidemic and the complicated international economic situation, the overall economy has recovered, agriculture has continued to maintain high-quality and steady development, farmers’ living standards have been continuously improved, and the rural landscape has been further improved.

  The agricultural economy grew steadily and the grain output reached a new high. In 2021, the added value of the primary industry increased by 7.1% over the previous year, reaching 8,308.6 billion yuan, accounting for 7.26% of the GDP, which was lower than that in 2020. In the first three quarters, the total output value of agriculture, forestry, animal husbandry and fishery reached 9,286.34 billion yuan. Among them, the total output value of agriculture is 4,667.11 billion yuan, the total output value of forestry is 384.13 billion yuan, the total output value of animal husbandry is 2,832.90 billion yuan, and the total output value of fishery is 912.96 billion yuan.

  The comprehensive agricultural production capacity has been continuously improved, and the production of important agricultural products such as grain has made steady progress. In 2021, 100 million mu of high-standard farmland was built nationwide, and the mechanization rate of crop cultivation and harvest exceeded 72%, of which the comprehensive mechanization rate of wheat cultivation and harvest reached over 95%. The national total grain output reached a new high, reaching 1,365.7 billion Jin, an increase of 26.7 billion Jin over the previous year and a year-on-year increase of 2%. It remained above 1.3 trillion Jin for seven consecutive years, achieving "18 consecutive years of prosperity". The national grain planting area was 1.764 billion mu, an increase of 12.95 million mu over the previous year, with a year-on-year increase of 0.7%, which maintained the growth trend for two consecutive years.

  The agricultural product market operated smoothly, and the producer price dropped slightly. Basic self-sufficiency of grain and absolute safety of rations are the general pattern of grain supply and demand. Judging from the market situation of major cereals, the supply and demand of wheat and rice are basically stable, and the domestic supply of corn presents a certain gap. With the increasing demand for meat, eggs, milk and other products, the demand for feed grain represented by corn is also increasing. In addition, corn is still in the critical period of agricultural production structure adjustment. To some extent, China still needs to increase the import of corn and feed grain to meet the demand. Generally speaking, China’s annual rice imports account for about 2% of domestic production, wheat imports account for about 6% of domestic production, and corn imports account for about 10% of domestic production. Grain imports mainly play a role in meeting differentiated needs.

  In terms of livestock products, the production capacity of live pigs has fully recovered, and the supply of pork market is relatively sufficient in 2021. Especially since last October, the orderly development of the second round of central and local reserve meat storage has played an important role in ensuring the stability of the pork market and the interests of aquaculture enterprises.

  In 2021, the producer price of agricultural products fell by 2.2%. The overall price of grain increased greatly, reaching 13.8%, among which wheat and rice increased slightly, 6.6% and 1.9% respectively, while corn increased by 25.5%. The overall price of livestock products decreased by 17.9% year-on-year, mainly due to the decline in the price of live pigs, which decreased by 35.1%; However, the prices of cattle, sheep and eggs have increased in different proportions, among which the price of eggs has increased by 15.5%, which is higher than that of cattle and sheep.

  Farmers’ income and consumption increased rapidly.

  Farmers’ income grew steadily, and consumption increased steadily. In 2021, the per capita disposable income of rural residents was 18,931 yuan, a real increase of 9.7% after deducting the price factor, which was 2.6 percentage points faster than that of urban residents. From the perspective of income composition, farmers’ income mainly includes wage income, net operating income, net transfer income and net property income. In the first three quarters of 2021, the four types of income all increased. Among them, wage income is the largest source of farmers’ income, which is 6325 yuan, with a nominal increase of 15.3%, accounting for 46.1% of farmers’ disposable income; The net operating income is 4042 yuan, with a nominal increase of 6.7%, accounting for 29.4%, which is the second largest source of farmers’ income; The net transfer income reached 3002 yuan, a nominal increase of 11%, accounting for 21.9%; The net income of property was 357 yuan, with a nominal increase of 10.7%, accounting for 2.6%.

  In the first three quarters of 2021, the per capita consumption of rural residents was 4.7 percentage points higher than that of urban residents, and there was still a gap between the consumption level of rural residents and urban residents. In the expenditure structure of rural residents, the consumption of basic necessities such as food, clothing, housing and so on has grown steadily, among which the per capita expenditure on food, alcohol and tobacco accounts for 32% and the per capita expenditure on housing accounts for 21%. Due to the scientific coordination of epidemic prevention and control and economic and social development in various regions and departments, the impact of the epidemic has been basically overcome. Consumer spending on services and other supplies has shown a rapid growth trend throughout the year, but it has not yet recovered to the same level in 2019.

  The level of rural informatization has improved rapidly, and agricultural production has started to be digitized. The COVID-19 epidemic has made the role of rural e-commerce more prominent. According to the statistics of the Ministry of Agriculture and Rural Affairs, at present, the coverage rate of administrative villages of e-commerce service stations in China is about 80%, and the online retail sales of agricultural products in counties exceed 300 billion yuan, which is growing rapidly. Relevant research shows that the number of Taobao villages has exceeded 7000 in 2021. The overall promotion of rural revitalization will accelerate the popularization and sinking of digital technology and accelerate the digitalization of rural industries. In the field of smart agriculture, the digitalization of agricultural production is in the ascendant, and the construction of the whole industrial chain of single product big data, such as oil, natural rubber, cotton, soybeans and other products, has started, and the application fields of big data systems have been continuously expanded.

  The reform of rural collective property rights has completed the phased task, and the collective economy has become a new growth point. The task of rural collective property rights reform has been basically completed nationwide, and rural asset resources have been greatly revitalized through measures such as clearing assets, defining members, quantifying operating assets and establishing economic (stock economy) cooperatives. According to the statistics of the Ministry of Agriculture and Rural Affairs, by 2021, nearly 900,000 collective economic organizations at the township, village and group levels have been established in China, and the collective book assets have been checked and verified to be 7.7 trillion yuan (excluding resource assets such as land), including 3.5 trillion yuan of operating assets. The endogenous kinetic energy of rural development has been significantly improved, and the collective economy has become a new growth point, laying a solid foundation for achieving the goal of common prosperity.

  The pressure of farmland protection has increased.

  During the "14th Five-Year Plan" period, the key and difficult points of China’s economic and social development are still "agriculture, rural areas and farmers", and the potential stamina is also "agriculture, rural areas and farmers". In the face of the unprecedented changes in the world in the past century, China’s agricultural and rural development is facing new opportunities.

  The steady macroeconomic recovery has provided a good environment for China’s agricultural economic development. The World Bank and the International Monetary Fund estimate that the growth rate of China in 2022 will exceed the world average and developed economies. Domestic consumption is also gradually recovering. If the epidemic can be completely ended in 2022, domestic consumption will be revived and the economic growth rate is expected to return to the pre-epidemic level.

  The further deepening of international cooperation provides an opportunity for the development of international trade in agricultural products. The "Belt and Road Initiative" has brought great impetus to China’s agricultural international cooperation. In the first half of 2021, the trade volume of goods between China and countries along the Belt and Road reached 5.35 trillion yuan, a year-on-year increase of 27.5%, which was higher than the overall growth rate of China’s foreign trade, accounting for 29.6% of the total foreign trade. Among them, agricultural trade accounts for about a quarter of the total trade. RCEP (Agreement on Regional Comprehensive Economic Partnership), which came into effect on January 1st, 2022, will undoubtedly provide new opportunities for China to expand international cooperation in agricultural economy and trade.

  With the promotion of rural revitalization strategy, the pattern of giving priority to agricultural and rural development has gradually taken shape. Infrastructure construction is speeding up again, and government investment and social capital will be invested more in agriculture and rural areas for land, water conservancy, seeds, digitalization, logistics facilities, especially cold chain construction.

  Agricultural and rural development also faces several challenges.

  Ensuring the quantity and quality of cultivated land is still a great challenge for China’s economic development at present. At present, the cultivated land in China is about 1.92 billion mu, which is 113 million mu less than the 2.03 billion mu cultivated land in the second national land survey 10 years ago. In addition, China’s urbanization continues, the ecological environment pressure has not been fundamentally alleviated, and the pressure on cultivated land protection is increasing. To ensure food security, while keeping the red line of cultivated land firmly and ensuring the area of cultivated land, more effective measures should be taken to resolutely stop the "non-agricultural" and prevent the "non-grain" of cultivated land.

  The overall cost of agricultural products is increasing, but the price of agricultural products is weak or fluctuates greatly. Since the new century, China’s agriculture has gradually entered a high-cost stage. From the perspective of planting industry, the cost of agricultural input and labor input is increasing, which has seriously affected farmers’ enthusiasm for growing grain. Land rents are also rising. According to the survey of major grain producing areas, the land rent in Northeast China ranges from 500 yuan/mu to 600 yuan/mu, while in central provinces it ranges from 400 yuan/mu to 600 yuan/mu, while in some eastern coastal provinces the average land rent reaches about 1000 yuan/mu, which further squeezes the profit space of transferring land management rights to grow grain.

  The relationship between supply and demand of important agricultural products is in a tight balance. Soybean still needs to rely on imports to meet the demand. In 2021, soybean imports will account for nearly 60% of the total grain imports, but the rations are absolutely safe.

  It is worth noting that there is still great uncertainty in the international environment, and the protectionist policies of developed countries are on the rise repeatedly, which poses certain challenges to China’s food security and sustainable agricultural development.

  It should also be noted that China’s urbanization is still continuing, and the population is accelerating to gather in major developed areas. At present, the resident population in cities and towns has exceeded 900 million. The resident population in rural areas continues to decrease, and the aging trend is still intensifying, which will be an important problem that must be solved in rural revitalization in the future. In recent years, the income gap between urban and rural areas in China has been narrowing, but the per capita disposable income of rural residents still lags behind that of urban residents. In 2021, the income ratio between urban and rural residents was 2.50, which was lower than the previous year, but the absolute value of the income gap between urban and rural areas was still 28,481 yuan. The reality that the income gap in rural areas has not been significantly alleviated will also affect the realization of the goal of common prosperity.

  The momentum of sustained and rapid development in 2022

  Combined with the employment population and social fixed assets investment in agriculture, industry, agricultural products processing and service industries in the last 10 years from 2011 to 2020, a prediction model was established according to the latest input-output table of 135 departments in China, and the report results were simply averaged by setting different simulation schemes, so as to judge the development trend of agriculture and rural areas in China in 2022 as follows.

  It is expected that the economy will continue to grow. In 2021, China actively responded to the impact of the epidemic, and GDP growth exceeded the pre-epidemic level, from recovery to high-quality growth. It is estimated that the contribution of primary industry, secondary industry and tertiary industry to GDP will reach 0.4%, 1.9% and 2.8% respectively when the economic growth rate exceeds 5.0% in 2022.

  It is estimated that the growth rate of agricultural added value will be 5.67%, maintaining a rapid and stable growth rate. The proportion of agricultural added value has increased, which may reach about 8%. The added value of processing industries (grain grinding products, feed processed products, vegetable oil processed products, sugar materials and sugar products, meat processed products, aquatic products processed products, vegetables and fruits processed products, dairy products and tea) with main agricultural products as raw materials will continue to grow, with the growth rate reaching about 3.0%, accounting for about 1.6% of GDP.

  It is estimated that the trade volume of agricultural products will reach US$ 350 billion, of which the export volume of agricultural products will reach US$ 80.7 billion and the trade deficit of agricultural products will reach US$ 188.6 billion, up nearly 40% year-on-year. Imports of edible oil seeds, edible vegetable oils and livestock products account for about 50% of domestic agricultural products imports.

  It is estimated that per capita disposable income will exceed 40,000 yuan, including 20,300 yuan in rural per capita disposable income, which is estimated to increase by 8% year-on-year, 2 percentage points higher than that of urban residents. It is estimated that the per capita consumption expenditure of residents will be 24,000 yuan in 2022, an increase of 5.3% over 2021; The average consumption expenditure of rural residents is about 15,000 yuan, an increase of 6.8% over 2021 and 2.4 percentage points higher than that of urban residents.

  On the whole, it is predicted that the development of agriculture and rural areas in China will be faster than other departments in 2022, the strategy of giving priority to the development of agriculture and rural areas will continue to advance steadily, and the gap between urban and rural areas will be further narrowed. However, while maintaining optimism, we should also have psychological preparation and coping strategies for two situations. First, the COVID-19 epidemic has not been eliminated, especially the global spread is still continuing; Second, the long-term slowdown in economic growth has become a subject that must be faced after the new normal of the economy.

  Hold the bottom line and achieve the set goals

  In the next few years, the development policy of China’s agriculture and rural areas will still be to maintain stability and strive for progress. In 2022, the bottom line that agricultural and rural work must keep is to stabilize grain, increase oil and protect cultivated land, and there will be no large-scale return to poverty. In order to actively respond to the challenges faced in the development process and achieve the established goals, the following layout can be made in a targeted manner.

  First, strengthen the construction of high-standard farmland and continuously improve the level of improved agricultural varieties. It is necessary to fulfill the task of ensuring the supply of primary products proposed by the Central Economic Work Conference and ensure that Chinese’s rice bowl is firmly in its own hands at all times.

  First, we must accelerate the pace of high-standard farmland construction and stick to the bottom line of grain production. In recent years, remarkable achievements have been made in the construction of high-standard farmland in China. It is estimated that 1 billion mu of high-standard farmland will be built by 2022, so as to achieve a stable guarantee of grain production capacity of more than 1 trillion Jin. At the central level, the subsidy funds for farmland construction should gradually tilt to the main grain producing areas, and the grain production in various places should be taken as an important reference for the allocation of funds, so as to ensure stable and high yield in the main grain producing areas with high-standard farmland; In the process of implementation in various places, we can flexibly adopt a variety of subsidies and incentives to guide the investment of financial, social capital and new agricultural business entities, and at the same time establish and improve the participation mechanism of farmers to mobilize their enthusiasm for farmland construction and protection.

  Second, we must constantly improve the level of improved agricultural varieties. By the beginning of 2021, China has 520,000 germplasm resources, making it the second largest country in the world. At present, the planting area of self-bred varieties accounts for more than 95%, and the two major grain crops, rice and wheat, are completely self-sufficient, so that China has achieved China varieties for grain, and the safety of agricultural varieties in China is generally guaranteed. On the one hand, we should continue to promote the cooperation among scientific research institutions, seed enterprises and agricultural management entities, and accelerate the cultivation and marketing of improved varieties. On the other hand, we should continue to increase support for seed production counties and regional seed breeding bases, support local governments to create modern agricultural industrial parks focusing on seed industry, improve the modernization level of the industrial chain of the base, and increase seed production capacity.

  The third is to guide the increase of soybean and oil crops. It is necessary to guide and encourage farmers to increase production of soybeans and oil crops in light of the current domestic demand for agricultural products. In the main producing areas of soybean and oil crops, subsidies are given to agricultural production links and credit insurance and other services are provided in combination with local financial conditions.

  Second, develop and expand the new rural collective economy to increase farmers’ income. As an important support for rural modernization and common prosperity, the new rural collective economy helps to attract young and middle-aged laborers to return, improve the property income of rural residents, and then narrow the income gap and promote the development of rural industries.

  First, we should base ourselves on our own advantages and revitalize idle resources. Villages in all regions should make full use of local superior resources, adopt independent management, leasing, shareholding, etc., take advantage of location, and develop cultural services, management services, logistics economy and other services to revitalize idle construction land, homesteads, farmhouses and old office buildings. At the same time, take agricultural industrialization as the core and promote the development of characteristic industries. Promote the integration of rural primary, secondary and tertiary industries, let farmers participate more in the development of industrial chains, and leave more value-added benefits to farmers. The second is to let grassroots party organizations be "leading geese". To fulfill the requirements of the main tasks of the Party’s rural work in the new era, we should give full play to the role of grass-roots party branches. Mobilize the masses, develop rural industries, and effectively link the interests of village collectives and farmers by leading and running cooperatives.

  Third, continue to expand the main body of new agricultural management and promote the organic connection between small farmers and modern agricultural development. In 2021, the number of family farms and farmers’ cooperatives reached 3.9 million and 2.2 million respectively. In the future, we should continue to support the cultivation of new agricultural business entities such as family farms and farmers’ professional cooperatives, improve the financial and monetary policy system, provide financial and tax support, technical guidance and risk control for the development and growth of new agricultural business entities, and make them play an exemplary role in stabilizing production and ensuring supply. Through policy incentives, a number of productive service organizations covering the agricultural industrial chain, with high degree of specialization and standardized behavior will be formed to promote the standardized cultivation of agricultural products in China and achieve the development goals of reducing agricultural costs, increasing production and improving quality.

  We should speed up the construction of a productive socialized service system for small farmers. At present, there are 955,000 socialized agricultural production service organizations in China, covering an area of 1.67 billion mu, driving more than 78 million small farmers. Agricultural productive socialization service is an important way to realize the scale of modern agricultural technology and equipment operation under the background of a large number of small farmers, which is suitable for the subjective and objective requirements of small farmers’ integration into modern agricultural development at present, and more effective policy measures should be taken to promote their healthy development.

  Fourth, speed up the optimization of trade structure to ensure the supply of major agricultural products with double circulation. We should make full use of domestic and international markets and resources, actively promote the coordinated development of domestic demand and external demand, import and export, and effectively use the international market to meet domestic food demand. In the past 10 years, China’s grain imports have generally shown an upward trend, and the grain imports have more than doubled. China’s rising grain output has not reduced its dependence on grain imports.

  During the "Fourteenth Five-Year Plan" period, it is necessary to actively promote the diversification of China’s grain import sources and expand import channels. First, we must strengthen in-depth cooperation with countries along the Belt and Road Initiative; Second, we should actively broaden the overseas agricultural industrial chain, increase cooperation with relevant overseas grain enterprises, provide agricultural production services for local growers, especially investment in warehousing and logistics, and realize the control of the whole industrial chain. Especially with the entry into force of RCEP, the threshold of cross-border agricultural investment cooperation has been significantly reduced, and it is necessary to actively carry out regional agricultural industrial chain value chain cooperation.

  However, we need to be alert that the epidemic situation in COVID-19 continues on a global scale, and we should effectively deal with its possible negative impact on grain trade, especially to avoid the excessive dependence of major imported agricultural products on a single country and prevent the grain supply chain from breaking.

  Fifth, promote agricultural insurance and improve the market regulation and reserve system. In recent years, the market of agricultural products has fluctuated greatly, which has affected the healthy development of agricultural industry. It is necessary to vigorously promote agricultural insurance, establish a complete risk dispersion system, improve the market regulation and reserve system, and enhance the anti-risk ability of producers and operators of important agricultural products. First, we should improve the agricultural reinsurance system to effectively balance the regional risk differences. Use agricultural reinsurance business to eliminate the fluctuation of direct insurance business, and steadily promote subsidies for high-risk business of direct insurance business, so that insurance companies can focus on service capacity building and continuously improve the level of agricultural insurance protection. The second is to promote agricultural catastrophe insurance. On the one hand, it is necessary to expand the pilot scope of agricultural catastrophe insurance and cover major crops and important agricultural production activities as much as possible. On the other hand, it is necessary to establish a multi-channel agricultural insurance catastrophe risk fund, combine reinsurance to innovate financial instruments, and use diversified risk diversification tools to securitize agricultural catastrophe risks.

  Promote the reform and improvement of the grain reserve system. In addition to natural risks, agricultural producers and operators have to deal with market risks. In recent years, the price fluctuation of major grain crops has intensified, and it is necessary to further strengthen the macro-control ability of the market. First, we should promote the reform and improvement of China’s grain reserve system in a timely manner and establish a special grain reserve for market regulation in line with the central grain reserve. Second, it is necessary to reform the existing grain purchasing and storage mechanism, and change the temporary "skimming surplus" purchasing and storage to the domestic and foreign markets.

  Sixth, improve the logistics conditions in rural areas and promote the circulation of agricultural products and the consumption of rural residents. In order to promote the circulation of agricultural products and boost the consumption of rural residents, it is imperative to further improve the logistics conditions in rural areas in addition to ensuring the continuous growth of rural residents’ income. Logistics conditions belong to "hardware facilities", so it is necessary to speed up the improvement of the three-level logistics system in counties and villages and smooth the two-way circulation between urban and rural areas. By means of "express delivery into the village", farmers can efficiently connect with the market, which not only allows the means of production and consumer goods to enter, but also allows agricultural products to come out and realize the smooth flow of things.

  Seventh, continue to consolidate the achievements of tackling poverty and prevent large-scale return to poverty. Promote the promotion of characteristic industries in poverty-stricken areas, and continue to tilt financial funds to poverty-stricken areas to support the development of local industries; Use microfinance, agricultural insurance and other means to support poverty-stricken households to develop industries; Promote the stable employment and income increase of the people out of poverty, increase on-the-job training, and actively carry out labor cooperation.

High fever to 40℃! Influenza has entered a high incidence period, how to prevent it scientifically →

near future

Influenza, mainly influenza A, has entered a high incidence period.

Two weeks in a row

Pediatrics in major hospitals in our city have seen a peak of medical treatment.

The topic of influenza has attracted much attention.

So, how should children be prevented and treated scientifically?

it is reported

Recently, the number of influenza patients in outpatient and emergency departments has increased greatly.

Most of them are infected with influenza A virus.

And the patients are mainly children.

According to doctors, influenza A is an acute respiratory infectious disease. Once children are infected, they are prone to high fever with a body temperature of 39℃ to 40℃. The incubation period of influenza A is very short, usually only 1 to 3 days.

Doctors reminded that vaccination with influenza vaccine can significantly reduce the risk of serious complications. The most important thing to prevent influenza is to maintain good personal hygiene habits, including wearing masks, washing hands frequently, and often ventilating, and trying to avoid going to crowded places during the flu season. Once you have symptoms such as high fever, chills, fatigue, muscle pain, loss of appetite, you must seek medical attention in time.

The National CDC also reminded

There is a risk of COVID-19 epidemic rebounding in winter and spring, and the national influenza epidemic is still at a high level. It is predicted that during the Spring Festival, most parts of the country will still face the risk of alternating or co-epidemic of influenza, syncytial virus, mycoplasma infection and other respiratory infectious diseases. Everyone should do a good job in health protection and respond scientifically.

Is the flu the same as the common cold?

What are the disinfection methods for influenza virus?

Let’s take a look

As the holidays approach, markets at all levels will actively mobilize sources of goods to ensure stable prices.

CCTV News:In order to ensure that everyone’s choices on the dining table are sufficient and fresh during the festival, markets at all levels actively reserve goods and strive to keep the stalls open, not out of stock and stabilize prices.

In the "vegetable basket" product area of some supermarkets in Lu ‘an, Anhui Province, the reporter learned that in order to ensure the fresh listing of important agricultural products every day, the local direct supply mode of connecting production bases with supermarkets was implemented to strengthen the connection between production and sales.

Ding Ling, head of a supermarket in Lu ‘an City, Anhui Province:Mainly from large bases, we have various procurement supply chains to maintain. Whether it’s fruits and vegetables or rice flour and egg oil, we can supply it without any problems.

Shandong Heze, a farmer’s market, is 1-mdash ahead of schedule; Dispatch market information and merchant demand information for 3 days, mobilize business households to increase capacity adjustment, and encrypt replenishment frequency to ensure that the daily supply during the National Day is 1.5 to 3 times that of usual.

Li Hongen, Deputy General Manager of a Vegetable Basket Operation Co., Ltd. in Heze City, Shandong Province:If some goods are difficult to purchase, we will assist merchants to collect them in our upstream wholesale market or base. At the same time, we will uniformly allocate the goods in the other three markets to meet the sufficiency and balance of goods in the whole market.

In this seafood hypermarket in Sheyang, Jiangsu, a large number of fresh catches are listed. The local government actively guides the online and offline integration of major commercial enterprises to ensure uninterrupted supply. Up to now, nearly 500 tons of fresh food, 2,980 tons of frozen products and 80 tons of various deep-processed seafood have been prepared.

Gu Jinli, a merchant of seafood hypermarket in Sheyang County, Yancheng City, Jiangsu Province:At present, we are working overtime to prepare the goods, because we have just started fishing, and the supply is quite sufficient, including about 20 kinds of specialties of the Yellow Sea, such as yellow croaker and hairtail.

In Jilin Province, the largest wholesale distribution center for vegetables, grain and oil, the reporter learned that since September 15, the daily purchase volume of the market has increased by 300 tons. At the same time, more than 2,600 tons of vegetables have been reserved here to cope with sudden situations such as cooling and epidemic.

Han Hongyang, Director of Market Management Department of Grain and Oil Market Branch of a Logistics Company in Changchun:At present, the daily purchase volume of our market is 1600 tons to 1700 tons. During the "Eleventh Five-Year Plan" period, we will organize merchants to increase the purchase volume to ensure stable supply.

Cadillac XT5 is ready for entry! 265,900 for sale, full of new gadgets.

On September 28th, before the National Day holiday, Cadillac officially announced the launch of the new generation XT5. Although its guide price of 399,900-459,900 seems a bit high, Cadillac also announced the launch of a limited-time preferential price at the press conference. Now the actual price range of the new generation XT5 is 26.59-335,900, which is full at once.

?

You know, compared with its BBA rivals, XT5′ s new car advantage is obvious, and Cadillac attaches great importance to XT5 this time, and all kinds of configurations can be said to be full. At this stage, when you want to buy a luxury brand medium-sized SUV with a budget of 260,000 yuan, the new generation XT5 is probably the most cost-effective choice at this stage.

?

So how to choose several versions of this replacement car with full configuration? How about the direct entry version?

In fact, although many domestic cars of 200,000-250,000 grades have achieved entry-level high allocation, that is, all versions are standard in key configuration, even if you buy the lowest allocation, the experience will not be much worse. However, in the field of joint venture vehicles, this approach of getting started and matching is relatively rare. But obviously, the new XT5 is completely in line with domestic cars in this respect.

?

This is a standard car with most key configurations, with a body size of 4888*1957*1694mm and a wheelbase of 2863 mm. The engines are all 237 2.0T machines with LXH model (burning No.95 oil), with cylinder closing technology, 48V light mixing and 9AT gearbox. The suspension is also a rear five-bar suspension.

?

At the same time, it comes standard with timely four-wheel drive, which most of its competitors can’t do at this price. Similarly, L2 system, Cadillac’s specialty headlights, double-layer sound insulation glass+rear privacy glass, and the 33-inch 9K resolution curved surface screen with amazing size and resolution are all standard. Of course, the seat comfort emphasized by the new car at the press conference is naturally standard in the whole system without castration. It can be said that most of the products mentioned at the press conference are standard in this car.

?

This hands-on style is enough for XT5 to distance itself from other luxury brand rivals at the same level. It also makes the choice of three configurations of this car less difficult.

Considering that this car is equipped at the beginning of the whole system, most of the configuration differences of its three versions are actually focused on something that enhances the driving experience. There are three configurations in the new car, among which there is not much difference between the top configuration and the middle configuration, and the price difference between the middle configuration of 295,900 and the top configuration of 335,900 is quite large, so we suggest that you choose between the low configuration and the middle configuration.

?

The low allocation is 265,900, the middle allocation is 295,900, and the difference is 30,000. What can I get for this 30,000 yuan? Let’s give you a list below: the exterior rearview mirror has more reversing, more steering wheel heating, more streaming media interior rearview mirror, more independent lumbar support adjustment for the main and passenger seats, more ventilation function for the front seats, and more heating function for the second row seats. In addition, the biggest difference is the sound system. The low one is a 7-speaker sound with unknown brand, and the middle one is a 15-speaker AKG sound.

?

To be honest, compared with the price difference of 30 thousand, these configurations are actually not so valuable. Therefore, our suggestion for buying a car is that, considering that the basic configuration of the new XT5 is high enough, we can directly buy the 2.0T luxury model of 265,900 yuan, that is, the low allocation is enough.

Obviously, XT5′ s competitors have always been the three explosive cars of BBA. XT5 and their competitive advantages have always focused on price and configuration, and this generation of models is no exception, but compared with the competition pattern eight years ago, the new XT5′ s basic configuration is now more complete, and its competitive advantage is greater than BBA’s three competitors.

?

Even compared with luxury brands such as Volvo, the new XT5 has no small advantage in configuration. It can be said that in the field of medium-sized luxury SUV, the current competitiveness of the new generation XT5 is very strong, and it is very promising to become the benchmark car in the market segment.

?

However, as for the comparison with domestic brands at the same price, the configuration is actually similar, but most domestic cars at this price are already new energy sources. As a fuel vehicle, XT5 does have some pressure on these domestic new energy vehicles with larger size, longer wheelbase and more space. However, as a luxury brand, Cadillac’s brand tonality still exists.

?

Therefore, the XT5 will naturally become a new explosion model in the field of medium-sized luxury SUVs. There is no doubt that it will also become Cadillac’s new sales fulcrum in the field of fuel SUVs. We are extremely optimistic about the market prospect of this car.

Are seals fierce?

Yes, seals are usually considered to be very fierce animals. They mainly prey on fish and cephalopods, so their predation skills are excellent. When protecting themselves, seals also show strong aggression. However, compared with humans, seals are relatively small, so they may be at a disadvantage in conflicts with other large animals or humans. Generally speaking, although seals are fierce animals, they usually don’t take the initiative to attack humans.

How to solve the problem that mobile phones are prone to heat and power consumption? Have a coup

  Nowadays, smart phones have become more and more popular, and everyone is very concerned about the problem of mobile phone fever when using smart phones. As a kind of electronic products, it is obviously unrealistic to completely suppress the fever of smart phones, but we still have some tips to keep smart phones from overheating in daily use. Let’s take a look at the fever of the mobile phone. How to solve the problem of mobile phone heating and power consumption?

  First, the cause of mobile phone fever

  Battery reasons, running too many large programs, high CPU load, damage to internal components, etc.

  1. When the cell phone number strength is -75dBm, the signal strength becomes very poor. In order to ensure normal cell phone communication, the cell phone will automatically increase the transmission power. The higher the cell phone power, the greater the cell phone fever.

  2. Multiple background applications run together, which leads to CPU overload, and the thermal effect of the current generated by it can be imagined. Moreover, the theme, background and screensaver are all users of TV University, which leads to the fever of the mobile phone. Especially when navigation, games and videos are running, when these programs are running, gps navigation, Bluetooth, wifi or hotspots will be turned on, which is very easy to cause serious fever.

  3. When users use mobile phones to surf the Internet and transmit more data, the greater the power consumption, the higher the CPU utilization rate and the higher the calorific value.

  4. The power consumption of the mobile phone when talking for a long time or using audio and video is very large, that is to say, its battery has a small equivalent load resistance, and it is discharged with a large current when working. After discharging a part of electricity, the internal resistance of the battery increases, but the current required for the work of the mobile phone cannot be reduced, so a considerable part of energy is consumed on the internal resistance of the battery, which leads to the battery heating.

  5. Because people are used to holding the mobile phone with their hands, the mobile phone cannot dissipate heat. If you use your mobile phone for a long time and the heat dissipation is not good, it will also cause your mobile phone to heat up.

  6. Charging with a non-original charger leads to the fever of the mobile phone. Such a charger lacks a protection circuit, which cannot guarantee the stability of the current when charging, and it is easy to burn out the battery, shorten the service life of the battery, and even have the danger of explosion.

  7. When you play with your mobile phone while charging, the battery will heat up when it is charging, such as making phone calls and playing games, which will aggravate the fever. If the weather is hot and the mobile phone is covered, the mobile phone is very easy to get hot, and it is also easy to get hot with a thick mobile phone cover. Encyclopedia of mobile phone case knowledge > >

  8. Hardware or battery failure of the mobile phone itself can also cause burning, but generally this kind of situation is less.

  Second, the consequences of abnormal fever in mobile phones

  If the abnormal fever of the mobile phone is not handled in time, it is easy to cause the following problems:

  1) The most direct thing is to damage the battery and reduce its service life.

  2) Damage to other mobile phone hardware, and the most extreme case is that the mobile phone explodes and hurts people.

  3) It may cause system disorder, and it is easy to dial the phone by mistake and open the application indiscriminately.

  Third, the handling method of abnormal fever of mobile phone

  After abnormal fever occurs, you can use the following methods depending on your environment and specific application:

  1) Physical cooling if possible. Put it in the air outlet of the air conditioner, or throw it into the refrigerator to cool down urgently. After the temperature drops, it won’t hurt the phone itself, then check what power-consuming programs are opened and turn it off.

  2) When it is already very hot, turn it off immediately. After shutting down, it is equivalent to killing all the programs, and then turning it on after the temperature drops.

  3) When the fever trend is relatively large, you can turn off gps positioning, wifi, Bluetooth and even direct flight mode. Or play games for a long time, just have a rest.

  4) Other conditions, such as unplugging the charging cable, removing the phone case, or getting hot, let the phone rest.

  Fourth, the reasons for mobile phone batteries

  The damage of mobile phone battery is an important cause of mobile phone fever. With the mass production of mobile phones, their quality is uneven. Especially the cell phone battery is a problem that puzzles people. If your mobile phone has two batteries, change the other battery to see if it is still hot. If it is no longer hot, it means it is a battery problem. If it is still hot, please see the second method.

  Solution to fever caused by running programs: Today’s smart phones can run applications that can only be run on computers before, but some inherent defects of mobile phones will bring us trouble, that is, fever. If you open too many applications, the load on the CPU of the mobile phone will be high, and the heat will be great. The solution is to close some large-scale running programs, and other programs that are not used should also be closed. If the phone is still hot after taking this method, please see the third method.

  Solution of internal component damage: If you use the above two methods, the phone is still very hot, then you should consider the problem of internal component damage. If your mobile phone is still in the warranty period, you can take your mobile phone to the merchant for warranty or replacement; If your mobile phone has passed the warranty period, you need to pay for it.

  1. When the mobile phone is at normal room temperature, it is normal for it to heat less than 50℃. When the mobile phone is very hot, remove the back cover of the battery and force heat dissipation.

  2. It is best to use the original charger, and it is best not to play with the mobile phone when charging.

  3. Develop a good habit of locking the machine; Don’t press the home button when you exit the program. Press home to build the program, which is still running in the background. Develop unused applications and clear them with one click in program management.

  4. Charging for too long will damage the battery and generate heat. The normal charging time of the mobile phone is 3-5 hours. How to charge the mobile phone > >

  5. If the mobile phone battery feels a little hot when charging, if it exceeds 50℃, immediately return to the standby state or replace the battery. If charging, immediately unplug the charger. What should I do if my mobile phone battery is not fully charged? > >

  6, often do the "one-click cleaning" background program for the mobile phone, and usually turn off some unused function switches, such as WIFI, GPS, automatic synchronization, etc., and appropriately reduce the screen brightness, which will greatly reduce the body heating phenomenon.

  V. Precautions for preventing abnormal fever of mobile phones

  Mobile phones are used for making phone calls, playing games, chatting, etc. It is impossible not to use them for fear of fever, but we can pay more attention to things at ordinary times, which can improve this situation. It can only be said that it is an improvement. If it is to be thorough, it can only rely on the improvement of the functional performance of mobile phone manufacturers.

  1) You can prohibit the background automatic update program of the mobile phone or the background upload and download of icloud. Because these may cause unexplained fever.

  2) Try not to play with your mobile phone while charging.

  3) If you wear a cover for your mobile phone, choose a material with better heat dissipation. If possible, you don’t need a cover. When you use your mobile phone in daily life, as long as you develop good habits, be careful not to fall and bump.

  4) If you are playing online games or navigating for a long time, control the time or take cooling measures.

  Six, mobile phone power consumption situation and solutions.

  Fast power consumption of mobile phones has always been a worry for mobile phone users. It’s a bolt from the blue when the mobile phone is playing without electricity. So is there any way to solve the problem of fast power consumption of mobile phones? The answer is yes! As long as you prescribe the right medicine for the following points.

  Case 1: There is virtual power in the mobile phone.

  There is virtual power in the mobile phone, which means that when you turn it on, it shows full power, but when you turn it off and then connect the charger, you find that the power display is actually only about 80%.

  The Android system generally judges the battery charge according to the battery voltage, and there are two modes to recognize the voltage.

  One is software identification, that is, the power displayed on the mobile phone after you boot into the system; The other is hardware identification, that is, when the charger is connected, the power displayed by the mobile phone is not turned on.

  Usually, the voltage of software identification is higher than that of hardware identification. Therefore, it will appear that when we turn on the battery, it is full. After turning off the battery and connecting the charger, we find that there is actually only 80% or even lower power. Want to fill it up? It will continue to charge for a long time!

  In fact, we often don’t fully charge our mobile phones, wasting part of the battery capacity, and naturally feel that the power is falling fast!

  Solution:

  Check whether there is virtual power in your mobile phone first: it is fully charged when it is turned on, and then turn it off and connect the charger to see if it is fully charged. If there is virtual electricity, then turn it off and fully use it, and see if it will be powered off again!

  Case 2: Too many background programs increase CPU power consumption.

  Don’t be careless about this old-fashioned question. What’s not so good about Android is that it will automatically run in the background after the program exits. Moreover, in the case that there is generally no problem with mobile phones, these background programs are often the biggest culprit in power consumption!

  There are also the screen brightness of the mobile phone itself, the opening of wifi, Gps, Bluetooth, etc., and other settings, etc. These seemingly insignificant little things are actually big power consumers.

  Solution:

  1. Clean up the background operation of the mobile phone regularly to solve the problem that unnecessary programs occupy running memory and increase CPU power consumption.

  2. Turn down the brightness of the mobile phone screen, turn off wifi, Bluetooth, etc. when not in use, and turn off power consumption settings such as button sound and button vibration.

  3. Think about whether you have installed a program recently, uninstall it first, and see if the power consumption of the mobile phone is back to normal. Many small programs we ignored actually consume amazing power!

  Situation 3: Battery aging

  Nowadays, most smart phones use lithium batteries, and the average life of lithium batteries is 2-3 years. After 400-500 times of charging and discharging, it will accelerate the aging speed and become less and less durable.

  If we use the mobile phone battery incorrectly every day, it will easily lead to battery aging and battery life decline.

  Solution:

  Proper use of mobile phone batteries is the best way to prolong battery life.

  The problem to be solved now is, how do we judge whether the mobile phone battery is aging?

  1. If the battery has been used for a year or so, according to your usual usage habits, the mobile phone will charge quickly and consume electricity quickly, which is likely to have begun to age.

  2. Check to see if there is a bulge in the battery. If there is a bulge, it means that it is not just aging, but the battery is no longer usable. For safety reasons, it is better to change the battery as soon as possible.

  3. After using the mobile phone for a period of time, the battery body has been burning, so you should change the battery as soon as possible.

  Situation 4: Caused by improper brushing

  In order to get ROOT privileges or other factors, many people quickly brush up when they get a new machine. But not long after, I found that mobile phones are prone to various problems, especially the power consumption will increase rapidly, which is really disturbing!

  In this case, generally speaking, the brush is incomplete, resulting in program errors, and then the program will be run repeatedly, and the power consumption will naturally accelerate!

  Solution:

  The major brushing systems may have some defects more or less, and some programs on the mobile phone hardware can’t be called, and then these programs will be tried again and again, which is invisible to us. Only after brushing the machine and finding problems when using the mobile phone will we know!

  At this time, it is best to find someone to help you refresh the machine, refresh the original system or the official ROM system, and then manage the system startup and self-startup software, which can be solved perfectly.

  Case 5: Short circuit and leakage of the mobile phone motherboard.

  For those who are familiar with mobile phone hardware, you can manually remove it, and check whether a patch capacitor on the main board of the mobile phone is in poor contact, which leads to a short circuit and causes the mobile phone to heat up, and then check to see if there is any leakage.

  Of course, this must be tested by professionals, which is more difficult for ordinary people.

  Solution:

  Take it to a mobile phone after-sales service point for testing, or go to some regular mobile phone repair shops, and let professionals test it for you. After determining the problem, you can prescribe the right medicine!

  Seven, mobile phone power consumption is fast, you can also try the following methods.

  Don’t let the battery run out.

  The mobile phone battery is fully charged and then consumed, and this cycle avoids the "memory effect". In fact, this practice is only applicable to Ni-Cd or Ni-MH batteries, not to lithium batteries. At present, most smart phones use lithium batteries. The author suggests that in order to prolong battery life and protect battery health, users should fully charge their mobile phones before running out of power.

  Positioning setting

  When users use mobile phones, some LBS-based applications often track users’ location, which will also increase power consumption. Although the power consumption increases, users of these applications often use them, and tracking the location can make the applications serve users better. At this time, users can find the corresponding application in Settings-> Privacy-> Location Services, and set the location information that they are allowed to access as "during the use of the application", which can save a lot of electricity when the application is not used. Of course, if you don’t need the location service of this app at all, you can set it to "never".

  Better use of WiFi network

  Under normal circumstances, users want to be online around the clock. Mobile phone network is undoubtedly a good choice, but at the same time it also means faster power consumption, especially when the mobile phone signal in the user’s area is not good, the mobile phone will frequently search for operator signals, which will increase power consumption. At this time, if the WiFi network can be used, the mobile phone does not need to search for signals frequently.

  However, users need to remember that when leaving the WiFi hotspot, users can turn off the WiFi connection. Generally speaking, it is to let the mobile phone stay in a stable network, and it is not necessary to search for signals frequently, so that the mobile phone can save more electricity.

  Appropriate use of flight mode

  Similar to the situation mentioned above, there is no busy mobile phone or WiFi signal in the underground high-speed rail, because the mobile phone will keep searching for connections, which will lead to an increase in power consumption. The user can set the mobile phone to flight mode before returning to the place with signal. In addition, turning on flight mode before going to bed is also a good way to save electricity.

  Low energy consumption mode

  If you don’t have the rechargeable conditions at hand for the time being, and you want the mobile phone to save as much electricity as possible, users can consider turning on the low energy consumption mode of the mobile phone. Take the iPhone as an example. When the power is only 20% and 10%, the mobile phone will automatically remind the user to turn on the low-energy consumption mode.

  Low-power mode will temporarily reduce power consumption until your mobile phone is fully charged. When this mode is turned on, you will stop viewing acquisition, background application refresh and automatic download, and weaken or turn off some visual effects. When the iPhone is charged to 80% capacity, the low-power mode will be automatically turned off.

  Find a big power consumer

  Now, no matter which mobile phone, you can count the major power consumers in the system for a period of time. As long as you know who consumes a lot of power, users can optimize their use. The mobile phone is running out of power, and you must have overdone one of your applications. IPhone users can get an overview of the most power-consuming applications in the past 24 hours and the past week in the "Battery" option.

  Android users can also select the "battery" option, and the system will display a chart of power usage since the last charging and a list of applications that use the most power.

Mccain began to learn to use computers and never sent or received emails.

Topic: 2008 US Presidential Election


  Profile photo: On March 5th, US President, Republican Bush (right) and Senator John McCain from Arizona attended a press conference at the White House in Washington. Bush announced at the White House on the 5th that he supported McCain in running for the next president, which indicated that McCain’s position as the Republican presidential candidate in this year’s general election was officially recognized by our party.

  China. com: According to comprehensive reports, John McCain, the Republican presidential candidate in the United States, publicly revealed for the first time that he is trying to learn how to use a computer. At the same time, he admitted that he has never used email, and he did not particularly feel the need to use it.


  In an interview with a reporter from The New York Times, USA, McCain revealed that at the age of 71, he has not given up learning some new things, and he is studying how to use computers very hard at present, which he believes will help him better serve the American people after being elected president. Mccain said that he has made great progress in learning to use computers, and he already knows how to switch computers on and off correctly and perform routine operations, including using some commonly used office software. However, McCain also admitted that he didn’t learn how to send and receive emails in the process of learning to use computers, and he had never used email to contact others before. Mccain said that e-mail is people using computers to ditch.


  But he always felt that he didn’t need to use e-mail, but he wouldn’t rule out that he would choose to use e-mail to communicate with support in the future.


  Although McCain is not proficient in computers, he is very concerned about the development of the Internet. He had previously said in a joking tone that he would use Google search engine to find a vice presidential running mate. When attending a fund-raising luncheon, McCain said that the Republican Party has listed a number of candidates for vice presidential running mate, and he has been actively negotiating with senior Republican Party officials on this matter recently. Mccain said in a joking tone that he would use Google search engine to investigate the popularity of these partners and select the deputy candidates who can win the Republican Party. Mccain said that Google’s search engine is very powerful, ranking first in the United States and even in the world, which can directly reflect public opinion. If you search for the name of the vice presidential candidate, you can know who is more popular with the American people from the interview results. Mccain said, "You know, it basically depends on Google. You can find everything you want on the Internet, which is really incredible."


  In an interview with reporters, Frank Frankoff, the former chairman of the Republican National Committee of the United States and the president of Commission on Presidential Debates in 2008, said that this year was not a very favorable year for the Republican Party to run for the presidency. President Bush was very unpopular in the United States, and there were also many problems such as the Iraq war, high oil prices and the economy. If things get worse, the party to which the White House owner belongs will be held responsible. The presidential election is different from all other election rules. In other elections, the winner usually gets the most votes, but this is not the case in the US presidential election. Candidates will pay attention to each state and regard each state’s campaign as independent. So, when you look back on the election in 2000, Gorbi Bush won 550,000 more votes, but he still lost because Bush won 271 delegates. When the high-level meeting of the Republican Party is over, people can not only know who is the candidate for president and vice president, but also know the policy program of the political party, but under normal circumstances, these policies are not really implemented.


  At the age of 71, McCain was selected by Time magazine as one of the 25 most influential people in America. In a recent opinion poll conducted by American media, about 19% of Americans think that McCain’s age is too old for running for president.
