　　BEIJING, Beijing, June 8 (Shang Qi) This year marks the 40th anniversary of the resumption of the college entrance examination system in China. Since 1977, the college entrance examination has influenced and changed the fate of several generations of China people. The gross enrollment rate of higher education has exceeded 40% from less than 2% at first, and is rapidly approaching the 50% popularization index line. Behind the data, how has the college entrance examination influenced and changed China in the past 40 years? 40 years later, what expectations has the college entrance examination been given by this country?

　　the resumption of college entrance examination

　　— — China’s concept of talents is changing.

　　On October 12, 1977, the State Council approved the Opinions on the Enrollment of Colleges and Universities in 1977 formulated by the Ministry of Education, which stipulated the new enrollment policy of colleges and universities, namely, abolishing the recommendation system, resuming the cultural examination, and selecting the best students.

　　This year, the slogan of "respecting knowledge and talents" took root in China. Li Muzhou, director of the Institute of Higher Education of Hubei University School of Education, has studied the examination system in China for many years. In an interview with a reporter from Zhongxin. com (WeChat WeChat official account: cns2012), he said that at the national level, the resumption of the college entrance examination 40 years ago is to show that the country attaches importance to talents and reconstructs the concept of talents.

　　He explained, "the resumption of the college entrance examination has confirmed the basic role of cultural knowledge and intellectual factors in the selection of talents in colleges and universities. This is a major change in the concept of national talents, and it can also be said that it is the correct return of the concept of national talents."

　　Education in China experienced a "warm winter" in 1977. According to statistics, at the end of that year, about 5.7 million young people "returned" to the college entrance examination, and colleges and universities selected 273,000 students, which greatly improved the quality of freshmen.

　　Over the past 40 years, college students selected through the college entrance examination have gone to various fields in China in batches. They witnessed and participated in the whole process of reform and opening up, and gradually became the backbone to promote the development of this country.

　　Recently, Liu Haifeng, member of the National Education Advisory Committee and director of the Examination Research Center of Xiamen University, wrote that since the resumption of the college entrance examination for 40 years, millions of qualified students have been selected for colleges and universities through fair competition in the college entrance examination, and many of them have become the backbone of all walks of life through training. China’s rapid economic development in recent years is inseparable from the recovery and continuous reform of the college entrance examination system.

　　40 years of practice

　　— — From elite education to mass education

　　"The college entrance examination has different meanings for people of different ages." Li Muzhou told Zhongxin.com that before the reform and opening up, the college entrance examination was largely about selecting national cadres. After the resumption of the college entrance examination, with the reform and opening up, the employment of college graduates gradually shifted from planned distribution to market competition, and more and more college graduates began to choose their own jobs.

　　As experts have said, in the past 40 years, with the changes in the country’s economic and social environment, the college entrance examination itself has also undergone changes. In 1999, the Ministry of Education issued the Opinions on Further Deepening the Reform of the Entrance Examination System in Colleges and Universities, and announced the national college entrance examination reform plan, which opened the prelude to the college entrance examination reform in this period. Since then, self-enrollment, self-proposition by province, and parallel volunteer admission have been explored one after another, and the recruitment methods of colleges and universities in China are more diverse.

　　Also in 1999, higher education in China began to expand the enrollment scale, and the admission rate of college entrance examination also began to rise sharply. According to statistics, from 1998 to 2005, the number of applicants for college entrance examination in China increased by 11.58% annually, and the number of college entrance examinations increased by 23.75% annually. By 2015, the number of students enrolled in higher education in China has reached 37 million, ranking first in the world.

　　According to China Education Online’s 2017 Survey Report, under the background that the total enrollment of college entrance examination has remained stable, the enrollment ratio of college entrance examination in all parts of the country has continued to increase. Among them, the gross enrollment rate of higher education has crossed 40%, rapidly approaching the popularization index line of 50%.

　　Compared with the gross enrollment rate of 1.55% in 1978, some people think that higher education in China has gradually moved from "elite education" to "mass education".

　　Li Muzhou said that higher education will enter the stage of popularization in the future, and the improvement of the popularization rate is conducive to the overall improvement of national literacy. He believes that "the future lies not in whether you have attended a university, but in what university you have attended, and this influence may be even greater."

　　Knowledge changes fate.

　　— — Social strata circulate in relative fairness.

　　From "elite education" to "mass education", behind the overall improvement of the popularization rate, the educational equity behind the college entrance examination has always attracted public attention.

　　Last year, Bian Yanjie, dean of the School of Humanities and Social Sciences of Xi ‘an Jiaotong University and sociologist, presided over a report entitled "Career Opportunities for Rural College Students". According to media reports, all the target samples of the survey came from the existing labor force in the city and were divided into six groups: the first three received higher education, namely, urban college students, rural college students and non-transfer college students; The last three have not yet received higher education, including the general urban labor force, rural-to-non labor force and migrant workers.

　　According to the report, for college students from rural areas to urban areas, they have the same opportunities to work in party and government organs and state-owned enterprises, and they also have the same opportunities to engage in elite occupations, with similar economic income levels, while the three types of non-college students mainly engage in non-elite occupations.

　　Li Muzhou told the reporter of Zhongxin.com that the urbanization process in China is very fast, but the rural population still accounts for the vast majority. Therefore, the college entrance examination provides them with an important way to change their destiny through higher education.

　　The "Implementation Opinions of the State Council on Deepening the Reform of the Examination Enrollment System" issued in September 2014 clearly stated that the number of rural students attending key universities should be increased, and the national special plan for targeted enrollment in rural poverty-stricken areas should continue to be implemented, and key universities should target targeted enrollment in poverty-stricken areas.

　　The opinion also made it clear that subordinate universities and provincial key universities should arrange a certain proportion of places to recruit outstanding rural students from remote, poor and ethnic minority areas. In 2017, the number of rural students entering key universities in poverty-stricken areas increased significantly, forming a long-term mechanism to ensure rural students to attend key universities.

　　Changes and Invariance of College Entrance Examination in the Future

　　— — Do you still believe in "one exam will fix you for life"?

　　In recent years, whenever there is a college entrance examination, there will be doubts about the disadvantages of the college entrance examination in public opinion, such as "a thousand troops crossing the wooden bridge", "one exam will set you for life" and "the baton of the college entrance examination".

　　As for the current examination enrollment system in China, the above-mentioned "Implementation Opinions of the State Council on Deepening the Reform of the Examination Enrollment System" also points out that the examination enrollment system in China is generally in line with the national conditions, authoritative and fair, and is recognized by the society. However, there are also some problems that are strongly reflected by the society. The main reason is that the score theory affects the all-round development of students, and the students’ learning burden is too heavy. There are gaps in enrollment opportunities between regions and urban and rural areas, and the phenomenon of cheating extra points and illegal enrollment occurs from time to time.

　　Nowadays, the scale of high school graduates studying abroad in China is increasing. It is pointed out by some voices that the growing number of students studying abroad also reflects from one side that parents and students in China are "voting with their feet" in the face of the college entrance examination.

　　"This will force the reform of the domestic college entrance examination system." Li Muzhou said that the foreign enrollment system has its advantages, such as multiple examinations, rich and flexible subject design, and relatively strong autonomy of colleges and universities … … These are problems that have not been completely solved in China’s college entrance examination system.

　　In fact, the practice of the college entrance examination in the past 40 years has not remained unchanged. Qu Zhenyuan, president of China Higher Education Society, pointed out to the media that in recent years, all aspects of college entrance examination enrollment have been reformed, including examination subjects, examination contents, examination times, examination methods, scoring methods, proposition methods, voluntary reporting methods, admission system, college entrance examination time, and charging system, and almost no aspect has not been tried or touched.

　　The latest changes have appeared in this year’s college entrance examination. These days, high school graduates in Shanghai and Zhejiang are welcoming the first "new college entrance examination". The results of the college entrance examination are composed of three unified college entrance examination scores of Chinese, mathematics and foreign languages, and three students’ self-selected examination subjects. The foreign language test is changed from once a year to twice a year, and you can choose a better score to be included in the total score of the college entrance examination.

　　Chu Zhaohui, a researcher at China Academy of Educational Sciences, said in an interview with Zhongxin.com that the reform of the college entrance examination enrollment system will be in a period of fluctuation in the coming period, and the key to the reform of the college entrance examination is to implement more professional evaluation.

　　He said, "The current examination system can achieve good results through a lot of training, and the actual test results are relatively distorted. As a professional education evaluation, the influence of intensive training on the test results should be eliminated as much as possible."

　　Li Muzhou hopes that through the reform of system design, the situation of "one exam will be fixed for life" will be changed.

　　"For example, let students have multiple exams and even multiple admissions opportunities, and further strengthen the separation of recruitment. Colleges and universities should study their own school-running orientation, formulate examination plans that meet their freshmen’s characteristics, and gradually break the people’s inherent understanding of the college entrance examination." He said.

　　Obviously, 40 years later, the college entrance examination still carries the heavy expectations of this country. (End)

Yunnan golden monkey is a national first-class protected animal, which is mainly distributed in the alpine virgin forests in northwest Yunnan and southeast Tibet. It is known as the "Snow Mountain Spirit" and an endangered species in the red list of the World Conservation Union.

This is the Yunnan golden monkey in Shangri-La Yunnan Golden Monkey National Park, Diqing Tibetan Autonomous Prefecture, Yunnan Province (photo taken on March 16).

Around 1980s, hunting and logging destroyed the habitat of Yunnan golden monkey, and the number of monkeys once decreased, so the protection situation was grim. In order to save the endangered Yunnan golden monkey, China established Baima Snow Mountain Nature Reserve, explored the protection mode of "community condominium", combined protection with the survival and development of surrounding residents, and promoted the recovery growth of Yunnan golden monkey.

The monitoring results of Yunnan Forestry and Grassland Bureau show that after years of efforts, the protection effect of Yunnan golden monkey is obvious. The population of Yunnan golden monkey increased from about 1000 to 1500 in 13 groups in 1996 and 3000 in 18 groups in 2016 to more than 3300 in 23 groups at present.

Since 2019, 13 organizations including Yunnan Forestry and Grassland Bureau, Yunnan Green Environment Development Foundation and Nature Conservancy (TNC) have jointly launched the "Yunnan Golden Monkey Whole Territory Protection Network", trying to establish a multi-party joint protection mechanism, taking actions from patrol monitoring, corridor restoration, community participation, friendly development and public participation, and striving to achieve sustained and healthy growth of Yunnan Golden Monkey population and comprehensive improvement of the health level of its habitat ecosystem.

[EV Vision Technology Comparison] Nowadays, when vehicle electrification has become the mainstream of development, diesel locomotives seem to gradually withdraw from the rhythm of the historical stage. However, the reality proves that the models with internal combustion engines will not disappear for a long time to come, but will have certain advantages in some aspects. However, this species that does not suffer from "mileage anxiety" will make car owners suffer from another disease-"fuel consumption anxiety". Therefore, on the issue of how to treat it, plug-in hybrid models have become this good medicine.

Before, we made a comparison between BYD DM-i and Great Wall Lemon DHT (extended reading: BYD DM-i or Great Wall Lemon DHT, who represents the peak of domestic hybrid technology? ), which proves that domestic hybrid technology is gradually rising and has the strength to compete with foreign hybrid technology. Of course, this technical field in China is more than these two. Looking at the industry, basically most OEMs have started to develop their own latest hybrid technology, and among them, Chery’s Kunpeng DHT has become another new hot spot after the first two. If you look closely, you may find that compared with the hybrid technology of the Great Wall, the word DHT appears behind Chery’s technology. What is the difference between it and lemon DHT?

What does DHT mean?

If you answer what is the most obvious difference between Kun Peng DHT and lemon DHT, there is actually a difference in word meaning.

The DHT of great wall lemon is calledDedicated Hybrid Technology, the Chinese translation isSpecial technology for hybrid power, is a complete hybrid technical scheme, including engine, transmission, drive axle, battery and other components.

DHT of Great Wall Lemon

Chery Kunpeng’s DHT is calledDedicated Hybrid Transmission, that isSpecial gearbox for hybrid powerBased on the traditional fuel vehicle gearbox, some electrified components are added to realize hybrid power technology.

DHT of Chery Kunpeng

So it can be seen that there are some differences in the technical route between the two. Please look down.

Comparison of hybrid architectures

Dual-motor+engine combination may be the trend of hybrid technology development now. Take DHT of Great Wall Lemon as an example, it is a powerful three-engine/four-engine power system composed of a 1.5L/1.5T hybrid special engine, a highly integrated dual-motor hybrid gearbox and a 135kW three-in-one two-gear electric drive rear axle. Under this system, three different specifications of power (PHEV/HEV) assemblies suitable for Class A, Class B and Class C have been successively introduced. In addition, under the PHEV architecture, there is also a "1.5T +DHT130+P4" four-wheel drive powertrain, which corresponds to different levels of products to meet the diversified choices of users.

Specifically, the lemon hybrid DHT consists of a high-efficiency hybrid special engine, a highly integrated dual-motor hybrid gearbox and a 135kW three-in-one two-speed electric drive rear axle, forming a powerful three-engine/four-engine power system, which brings super power. The maximum power of HEV two-drive system is 180kW, and the total power of PHEV two-drive system can reach 240kW. The front and rear axle motors with PHEV+P4 structure can output power at the same time, and the maximum system total power can reach 320kW. The intelligent four-wheel drive system of this architecture has strong climbing ability, such as achieving 60%-65% maximum climbing degree when dry asphalt pavement and 15%-18% maximum climbing degree when snow.

High fuel efficiency hybrid special engine

In terms of transmission, Great Wall Lemon DHT is similar to Honda i-MMD, except that it has two gears when the engine is driven, while the latter has only one gear when the engine is driven. By selecting the gear, it can give full play to the performance advantages of the engine. The system also adopts dual-motor series-parallel topology, which can realize EV, series connection, parallel connection, energy recovery and other working modes, and achieve a perfect balance between power and fuel consumption in various driving scenarios. As for the battery, the Great Wall Lemon DHT architecture is equipped with the world’s largest capacity and high-efficiency hybrid battery, which has the highest performance in the industry with a pure battery life of 200km. With CTP(Cell to Pack) technology, the energy density of the battery pack reaches 160Wh/kg, and it supports 11kW AC slow charging and DC fast charging.

High integration hybrid DHT transmission

Although there is not much information about Chery Kunpeng DHT, we can still see the clue from the known information.

From this exploded view, we can roughly see the structure of the whole system. Chery Kunpeng DHT also uses the combination of engine and dual motors, but here I want to knock on a blackboard to draw a key point. Different from the mainstream development, Kunpeng DHT is the only hybrid architecture driven by dual motors in China brand at present. An output mode mainly driven by electricity can be provided. In this hybrid system, the motor bears the main driving responsibility, and the engine can supply energy for the power battery under low load conditions. Therefore, two relatively low-power drive motors are equipped with FIO fixed-point injection oil-cooled motor technology and TEM dual-motor power distribution technology developed by Chery, in order to replace the effect of a single high-power drive motor.

In terms of data, the maximum power output torque of Kunpeng DHT can reach 510N·m, and the whole box torque density is 35 N m/kg, which can match large and medium-sized cars and SUV models, and can realize nine high-efficiency working modes such as single/double motor drive, extended range, parallel connection, direct engine drive, single/double motor braking energy recovery and driving/parking charging. Kun Peng DHT adopts TEM ultra-efficient dual-motor power distribution technology, which can choose the best electric drive source and gear according to the load size to improve the driving efficiency, thus creating a smooth driving experience and more efficient power distribution. The maximum transmission efficiency is more than 97.6%, the average efficiency of electric drive in NEDC working condition is more than 90%, the peak efficiency of flat wire motor is more than 97%, the power is 6.0kW/kg, and the fuel saving rate in low power mode is more than 50%.

In addition, Kunpeng DHT has 11 combined gears (seemingly the largest in the world? ）。 However, it should be noted here that the gear position of Kunpeng DHT is not limited to these 11 combinations. Due to the existence of dual motors and the provision of a 3-speed transmission device in the engine direct drive mode. You know, most of the mainstream technologies now adopt a direct clutch structure, that is, the generator can directly drive the wheels. However, when they are all direct-drive output, they all have only one gear, which limits the highest efficiency working range (the difference between ordinary bicycles and variable-speed bicycles), so Kunpeng DHT is equipped with three gears on the engine to broaden the engine driving performance. First of all, the first speed ratio is relatively large, which is mainly used for starting and accelerating. The third speed ratio is very small, mainly to ensure low engine speed, low fuel consumption and noise reduction when driving at high speed. Among them, the second speed ratio mainly takes into account the shift of the first gear and the third gear to ensure the smoothness of the shift, and at the same time takes into account the fuel consumption at the middle and low speeds.

It is worth mentioning that these permutations and combinations can achieve dozens of gear combinations, but the manufacturer has chosen 11 most suitable gears. In different working scenarios, the built-in control system of Kunpeng DHT calculates the optimal working gear in real time, and cooperates with Chery’s FIO fixed-point injection oil-cooled motor technology, TEM ultra-efficient dual-motor power distribution technology and ultra-smooth TSD dual-shaft drive design to achieve the balance of power, ride comfort and economy.

Comparison of working principles

There are four working modes of Great Wall Lemon DHT, including pure electric drive mode, series mode, first gear direct drive mode (low speed cruise), first gear direct drive mode (performance direct drive), second gear direct drive mode (high speed cruise) and energy recovery mode.

The important core of overall fuel saving is to make the engine work in an efficient working point area. When driving at low speed in general urban areas, lemon DHT will switch between EV mode and series mode, and maintain the engine in the most efficient area. When driving in suburbs and viaducts, the series mode will still be adopted at medium and low speed, but at medium and high speed, the engine will start to intervene, and when encountering heavy load demand, the engine+parallel drive mode will be adopted, which not only maintains high efficiency, but also provides sufficient response for power. Finally, at high speed, the engine direct-drive working point will directly fall in the high-efficiency area, or when the power is enough, EV battery life will be adopted to reduce fuel consumption.

As can be seen from the published data, the working mode of Chery Kunpeng DHT can be said to be another way.

First of all, the front part will be equipped with a small displacement (1.5T) inverted engine. Why did you choose this engine type? First of all, the intake manifold of the inverted engine is shorter, and the air intake is more direct and smooth. In addition, the air does not need to be heated above the engine to reduce the air density and oxygen content, so the engine burns more fully, the thermal efficiency is higher than that of the upright engine, and the fuel consumption is correspondingly reduced. In addition, this engine has a relatively compact volume to reduce the cabin space and lay the foundation for weight reduction because the intake manifold and exhaust manifold do not need to be wound up and down from the engine for half a turn.

The dual-motor part of the predecessor is composed of two low-power driving motors. Why choose two low-power drive motors but not one high-power motor directly? The reason for this is that if a high-power motor is used, the efficiency of the motor will be greatly reduced at first when it starts at low speed and runs at high speed, and when it enters the power loss state, the engine will start to intervene in power generation, and the fuel consumption will inevitably increase. Therefore, using two low-power motors can make the whole hybrid system work in a high-efficiency area with the same comprehensive performance. After that, it is combined with the previously mentioned Kunpeng DHT gearbox to achieve the purpose of fuel saving. In addition, after adopting the dual-motor scheme in manufacturing cost, the dependence on high-precision gears is relatively reduced. After all, this aspect can only rely on imports for the time being.

Who are the models under DHT technology?

WEY macchiato

On April 15th this year, Great Wall Motor conducted an online lemon hybrid DHT vehicle test, which was the first time to be tested with a real vehicle. The tested model was WEY Macchiato, which will be listed soon. This model is equipped with the latest lemon hybrid DHT technology of the Great Wall, and is also equipped with the combined configuration of 1.5L Atkinson cycle engine and motor. The maximum horsepower of the engine is 102kW, the maximum power of the motor is 154kW, and the combined maximum power is 190kW. It is worth mentioning that the fuel consumption per 100 kilometers is only 4.7L and the maximum cruising range can reach 1100km. The subsequent PHEV plug-in hybrid vehicle has a pure electric cruising range of 110km.

Tiggo 8 PLUS PHEV

Tiggo 8 PLUS PHEV is Chery’s first model equipped with DHT hybrid system, which adopts a three-motor four-wheel drive hybrid system with 1.5T turbocharged engine+front double motor+rear single motor. Among them, the maximum power of the engine is 125kW, the peak torque is 252N·m, the official 0-100km/h acceleration is only 4.9 seconds, and the comprehensive fuel consumption is only 1.3L/100km.

EV vision view:Although the published information is very limited, through the comparison of these two technologies, we can see that their innovation in hybrid technology is enough to compete with hybrid power enterprises, which not only opens the door to the development of domestic hybrid technology, but also makes China brand occupy a place in the world. At present, the latest "Roadmap 2.0 for Energy-saving and New Energy Vehicles" issued by China Automotive Engineering Society clearly puts forward that traditional vehicles should be fully "mixed" in the next 15 years. By 2035, among the non-new energy vehicles that still occupy half of the market, hybrid power will become the leading force. Therefore, the automobile industry has developed in parallel with many technical routes. In order to realize the low-carbon of energy-saving vehicles, the automobile factory must establish a new hybrid technical route. Therefore, both Kunpeng DHT and Lemon DHT will become the new trump cards representing the development of hybrid technology in China. In the future, EV Vision will dynamically evaluate two vehicles based on its own hybrid technology, so stay tuned!
