From the technical route, the development of hybrid electric vehicles is an important transition means from traditional fuel vehicles to new energy vehicles. The technology and products of hybrid electric vehicles have excellent performance, good energy-saving effect and moderate cost, so the market acceptance is increasing. From 2016 to 2021, the domestic plug-in hybrid vehicle market sales increased from 98,000 to 603,000, and the market scale increased by 6.2 times.

At present, according to the level of electrification, there are three main technical routes for hybrid electric vehicles: hybrid electric vehicle (HEV), plug-in hybrid electric vehicle (PHEV) and extended-range hybrid electric vehicle (REEV). Plug-in hybrid battery system often has a large capacity, which is easy to be supplemented by external power and has good fuel-saving potential.

Plug-in hybrid vehicle is a new energy vehicle between pure electric vehicle and fuel vehicle, which takes into account the advantages of pure electric vehicle and hybrid vehicle. With dual power of fuel and electricity, it can not only realize pure electric and zero emission driving, but also increase the driving ability of the vehicle through hybrid mode. The performance of plug-in hybrid electric vehicle is better than that of traditional fuel vehicle, and it is more suitable for the complex traffic environment in China than pure electric vehicle, which has both performance and economy.

The Roewe brand of Shanghai Automobile Group, a powerful manufacturer, has many products. There are two series in the new energy field: hybrid and pure electricity. The hybrid vehicles include eMAX, ePLUS and Roewe ei6 MAX. Today, let’s take a look at the technical performance of the 2020 car. This car has three models, namely PHEV cool version, PHEV cool canopy version and PHEV cool canopy intelligent driving Supreme version. The official guide prices are 136,800 yuan, 146,800 yuan and 156,800 yuan respectively.

The body specification of the 2020 Roewe ei6 MAX plug-in hybrid model is 4722MM*1835MM*1465MM, which is a compact model. The wheelbase is more than 2.7 meters, reaching 2715MM, so there is plenty of room in the car.

The 2020 Roewe ei6 MAX electric hybrid vehicle has six exterior colors, namely, atmospheric Ronglin gray, pearlescent black and bright white, fashionable Jade Bird Blue, Silver Leaf Gold and Red Flame Red, and the interior has two color systems, one is black, and the other is black/gray, with stable colors.

In terms of power, the 2020 model adopts a 1.5TGI in-cylinder direct injection turbocharged engine, with a maximum power of 124Kw and a maximum torque of 250N.m. The total power of the motor is 100 kW, the total torque of the motor is 230N.m, and the combined maximum torque of the engine and motor reaches 480 N.m.

In terms of power design, the 2020 models adopt many latest technologies. The first feature is that the second-generation dual-core plug-in hybrid system developed by Roewe is the "blue-core+green-core" plug-in hybrid system, which is two technology brands of Roewe. The blue-core technology fuel engine system and the green-core technology represent the hybrid mode, which is the accumulation and integration of traditional power technology and new energy technology respectively. This system has reached the world advanced level.

The second feature of the power design of the 2020 model is the adoption of the second generation HCU high-efficiency intelligent electronic control technology. The full name of HCU is Hybrid Control Unit, that is, the vehicle controller of the whole hybrid vehicle. For hybrid vehicles, it is the central controller of hybrid vehicles. Its functions are energy management, torque coordination and distribution, motor and battery coordination management, safety monitoring, fault diagnosis, braking energy recovery, etc. HCU can quickly adjust the power reserve according to feedback, and its control strategy determines the driving control, power performance, safety performance and economic indicators of the whole vehicle.

The third feature of the power design of the 2020 model is the use of 10-speed EDU second-generation intelligent electric drive. Shanghai Automobile Group is one of the few enterprises in China with technical reserves in three routes: hybrid, pure electric and fuel cell, and independently controls the core technologies of battery, electric drive and electronic control. The full name of EDU is Electric Drive Unit, that is, intelligent electric drive gearbox, which is the core component of power output. The first generation EDU adopts a plug-in hybrid scheme with two motors in series, that is, double motors and double clutches. When it is upgraded to the second generation EDU, it uses a single motor and an electronically controlled clutch. The second generation EDU has a higher gear ratio combination, that is, gears with different diameters mesh together to have a better rotational speed ratio, which brings more efficient power output to the vehicle. Moreover, after a single motor replaces two motors, not only the power performance is not reduced, but also the cost can be reduced.

The above power design makes the maximum speed of 2020 models reach 200 kilometers per hour. The acceleration time from 0 to 100 kilometers is only 7.2 seconds, NEDC’s comprehensive fuel consumption is 1.1L per 100 kilometers, and the comprehensive electric cruising range is 70 kilometers. Compared with the constant-speed cruising range, the comprehensive cruising range is the comprehensive cruising range under different road conditions, and NEDC considers more car scenarios.

　　First enrollment of 21 new majors

　　In April this year, the Ministry of Education announced the results of the filing and approval of undergraduate majors in ordinary colleges and universities in 2022. It is reported that there are 21 new majors listed in the catalogue in 2022, and another 925 majors have been revoked. At present, the undergraduate professional catalogue includes 93 professional categories and 792 majors.

　　Many new majors are closely related to social needs. Education for autistic children and barrier-free management newly added by Nanjing Special Education Teachers College, and family education newly added by China Women’s College; Some are closely related to urban and rural construction, such as the new rural governance in Hainan University and the new national park construction and management in Beijing Forestry University.

　　There are also some majors related to the development of cutting-edge technologies, for example, the earth system science newly added in Tsinghua University, the biomaterials newly added in South China University of Technology, and the future robot and electric vehicle engineering newly added in Southeast University.

　　In the latest catalogue of undergraduate majors, the cross-engineering specialty is added for the first time under the engineering category, and the robot specialty in the future is the first and only specialty under the cross-engineering category.

　　Which majors are attractive?

　　In recent years, the popularity of medical professionals has continued to increase. According to the data on the service platform "Pocket College Entrance Examination", the popularity of clinical medicine ranks first in the ranking of professional popularity.

　　At the same time, biostatistics is also the new major with the largest number of colleges and universities, including China Pharmaceutical University and Guangdong Medical University.

　　In terms of employment income, engineering seems to have more advantages. According to "China Undergraduate Employment Report in 2023" issued by MyCOS Research Institute, the 10 undergraduate majors with the highest monthly income of 2022 undergraduate graduates all belong to engineering. The highest is information security, with a monthly income of 7579 yuan, and the monthly income of information engineering, data science and big data technology, and software engineering also exceeds 7000 yuan.

　　In May this year, the average wage data of 2022 released by the National Bureau of Statistics also showed that the top three industries with the average annual wage level of employed people are information transmission, software and information technology services, financial industry, scientific research and technical services with high technical content.

　　Garbage is called "misplaced resources". How to put these resources back in place? The experience of various countries shows that sorting garbage from the source can help to recycle resources to the maximum extent, solve the "besieged city" of garbage and promote sustainable development.

　　America: Classification brings transformation.

　　When it comes to new york, it is difficult to associate this attractive international metropolis with a garbage city with sewage and stinking air. In fact, before the end of 19th century, new york was one of the dirtiest cities in the world. At that time, the streets of new york were littered with garbage, mosquitoes and flies danced wildly, and the foul smell made many residents never dare to open the window. Poor sanitary conditions became a hotbed of various diseases.

　　It was not until the appearance of health engineer George Welling that new york saw hope. In 1895, as the street sanitation commander, Wei Lin established the first garbage recycling and sorting system in new york history, put forward a series of regulations and specific measures for producing soap and agricultural fertilizer from food waste, and called on the whole people to pick up brooms to clean the streets.

　　Thanks to the joint efforts of the whole people, new york has gradually got rid of the dirty environment and established a more systematic and perfect method of garbage sorting and recycling. According to the latest law in 1989, new york residents must sort their garbage before they throw it away. Recyclable garbage is divided into two categories, paper and cardboard are one category, and metal, glass and plastic products are another category, which must be put into garbage bins of different colors respectively.

　　In recent years, new york has been exploring more detailed waste sorting methods, trying to recycle food waste separately and use it for biogas power generation and composting. The local government believes that increasing garbage recycling will not only help to purify the environment, but also save a lot of government expenses.

　　Japan: Close to the Extreme Classification

　　As a densely populated city, Tokyo, Japan, was once plagued by garbage siege and environmental pollution. At the end of 1970, the Japanese parliament completely revised the Cleaning Law and enacted the Waste Disposal Law to curb waste discharge and properly classify, keep, collect, transport, regenerate and dispose of waste.

　　With the long-term efforts of all walks of life, the urban environment in Tokyo has been greatly improved, and the garbage classification has become more detailed and complicated. Combustible garbage, noncombustible garbage, kitchen waste, metal garbage and plastic garbage … … The fine classification makes it not so simple to throw garbage.

　　For example, a cigarette box needs to be discarded in three categories: the plastic film wrapped outside is plastic garbage, the box is combustible garbage, and the aluminum foil at the seal is metal garbage.

　　Many garbage collection points can be seen in the streets and residential areas of Tokyo. These collection points are all posted with delivery instructions, which introduce the classification method and collection time of garbage in the form of pictures and texts, such as when to discard what garbage seven days a week. If you miss the specified time, you can only wait until the next collection day to lose it. If you want to throw away large pieces of garbage such as bicycles and wardrobes, you need to apply by phone in advance and buy treatment vouchers. The price of each piece ranges from several hundred yen to thousands of yen. If you throw away garbage at random, you will be fined or even imprisoned.

　　Germany: the details are constantly optimized

　　In Germany, domestic waste is roughly divided into non-recyclable waste, packaging waste, paper waste, biological waste, electronic waste, glass waste and so on, and their destination is trash cans with different colors.

　　Germany also promotes the recycling of beverage bottles by setting a deposit. For example, a 1.5-liter bottle of ordinary mineral water costs 0.19 euros, but an additional deposit of 0.25 euros is required for plastic bottles filled with water. You can only get the deposit back after the bottle is returned by the bottle collector in the supermarket.

　　With the participation of families, schools and other sectors of society, German children learn the method of garbage classification from an early age and take it as a natural thing. The waste treatment plant will also let people know more about waste sorting and its importance by organizing visits.

　　Garbage sorting and recycling has also spawned new business models, such as garbage management companies. Different kinds of garbage have different disposal fees. If recyclable garbage such as plastic packaging and paper products is put into a bucket of non-recyclable garbage, higher disposal fees will be paid. Garbage management companies can help people reduce the cost of garbage disposal as much as possible.

　　For example, entrusted by the community manager, the staff of the garbage management company will go to the community every three to five times to reclassify some misclassified garbage, and provide regular consultation activities to popularize the knowledge of garbage recycling to residents and help people classify garbage more accurately. Although residents have to pay part of the expenses of the management company, with the sharp reduction of garbage disposal fees, residents have not only saved money, but also contributed to environmental protection.
