Compared with the experimental data, the details of the adjustment of the plan, Zhang Guoqin is designing drawings in the office. Zhang Guoqin, 40, is an engineer of CRRC Changchun Rail Bus Co., Ltd. (hereinafter referred to as "CRRC Great Passenger"), and is also the electrical design director of the Beijing Zhang Zhang high -speed rail intelligent EMU.

Layers of mountains are stacked, and there are many rocks. The conditions of the high -speed railway line of Jingzhang are complicated. Once the vehicle fails, it will directly affect the operation of the entire line. In this regard, the Beijing Zhang high -speed rail intelligent EMU creatively configures the power battery system with a two -way charging function. With the current power and the location of the vehicle, the driver moves forward and retreats according to the current power and the location of the vehicle. You can walk to the nearest station emergency.

However, the independent research and development of this item is a lot of challenges. It has occurred several times that may lead to the failure of the entire plan. Zhang Guoqin and his colleagues are precise computing, field testing, and repeated tests. I don't know how many nights have been boiled. Finally, the design team handed over the answer sheet. On the basis of the Fuxing, it innovated and developed more than 70 intelligent sub -functions of 19 major items. High -speed EMU Smart Edition 1.0.

In recent years, CRRC's R & D team has continued to work and climbed the peak. Advancing into the self -developed unmanned area, the deputy chief engineer Chang Zhenchen led the team to the problem from the tens of thousands of lines. The network control system of the standard EMU of China achieved independent control; In the operation area, 7 points for precision welding ...

The high -speed rail is a beautiful business card in my country. Zhang Guoqin said that in order to control the right of technical speech, CRRC has a channel for talent development channels such as chief technical experts and senior technical experts, and provides the opportunities for high -level titles for young people who are appraisal. In the design team of the Beijing Zhang high -speed rail intelligent EMU, more than 90%of them are designers under 35 years old. In order to do a good job of the "bidding belt", CRRC encourages high -skilled leaders to form an operator workstation, which has accumulated more than 1,300 technical problems and tens of thousands of trainers.

In Gaojia Village, Lishu County, Jilin Province, more than 200 acres of test fields were in the heart of Yang Qingkui, head of the peasant cooperatives of the Kangda Agricultural Machinery Farmers' Professional Cooperative in Lishu County.

"At that time, this was a low -yielded field that no one was willing to plant." Yang Qingkui led the cooperative to try new technologies covered with corn straw on this land. earthworm. This new technology later had a loud name- "Pear Tree Model", and this test field became the longest protective farming research and development base in China.

"Science and technology help, we have achieved over -tonnage for 4 consecutive years." Last autumn harvest, Yang Qingkui lamented when we saw the result of 1077.94 kg per mu.

The "Pear Tree Model" windproof soil, fertilizer land, drought resistance, and cost -saving efficiency has become the consensus of more and more local farmers.

This year, Jilin Province optimized and promoted this model, promoting the protection area of ​​32.83 million acres, and the suitable area was fully implemented.

In recent years, Jilin Province has explored the establishment of a variety of black soil protection models through the protection paths such as the east of the Eastern Anti -soil, the improvement of the quality of the central region, and the improvement of fertilizer and the improvement of fertilizer in the west. At the Changling County of Songyuan in western Jilin, the Director of the Northeast Geography and Agricultural Ecological Ecological Ecological Ecological Ecology of the Chinese Academy of Sciences has built 500 acres of demonstration fields.

Last year, Jilin Province signed an agreement with the Chinese Academy of Sciences to fully implement the "Black Earth Greece" science and technology conference, and will build 3,000 acres, 30,000 acres of demonstration bases and a number of demonstration sites. At present, the province's exemption and sowing machines have reached 35,000 units, demonstrating the promotion of nearly 500,000 acres of straw and mixed fields, which is equivalent to the sum of the past three years. The rice bean wheel is used as 1.5 million mu, and the saline -alkali cultivated land treatment model is more than 300,000 acres.

"Tibetan grain is in the ground, hiding grain in technology, and protecting the black land, which is of great significance." Yang Qingkui said.

On April 30, with the successful launch of the "One Arrow and Five Star" in the East China Sea of ​​the Yellow Sea, the "Jilin No. 1" satellite added 5 stars; in just 5 days, another 8 stars were added. At this point, the number of "Jilin One" has increased to 54 in the rail satellite, becoming the largest commercial remote sensing satellite constellation in my country.

In Changchun New District, the development of Changguang Satellite Technology Co., Ltd. (hereinafter referred to as "Changguang Satellite") is very representative. It is the first commercial remote sensing satellite company in my country. Relying on the core key technologies such as "star carrier integration" and "airborne integration", it has established a complete industrial chain from satellite, drone research and development and production, to providing remote sensing information services to provide remote sensing information services. , And drive upstream and downstream enterprises. At present, the "Jilin No. 1" satellite has driven the rapid development of high -tech industries such as optical manufacturing, precision processing, and electronic information in the province. There are nearly 300 related supporting companies. Longguang satellite has also become the first "unicorn" enterprise in Jilin Province.

On the fertile soil of Changchun New District, a group of high -tech enterprises like long -light satellites are growing and expanding, opening up and downstream, stringing the industrial chain, and driving radiation with high -quality development. According to reports, in 2022, the Changchun National Independent Innovation Demonstration Zone with the main body of Changchun New District was approved. At present, the new district has established a modern industrial system supported by strategic emerging industries such as advanced manufacturing, biomedicine, aerospace. In 2016, Changchun New District became the seventeenth national new district approved by the State Council. In recent years, Changchun New District has regarded innovation as a key trick for intensive and connotative development, continuously improved the innovation model of government -based incubation gold coordinated innovation, and worked hard on the road of high -quality development -it has been approved as the country's "doubles double Create a "demonstration base, the national scientific and technological achievement transfer and transformation demonstration zone, and the national independent innovation demonstration zone. Changchun New District has cumulative 740 high -tech enterprises, 179 "specialized new" enterprises, an average annual growth of GDP, an average annual increase in industrial output value of 9.5%, and an average annual increase of high -tech manufacturing output value of 19.7%.

River Travel Convergence promotes rural revitalization

In the summer of July, when walking through the seedlings with high calves, when he saw Lin Zhongkui, a large grain planner in Yanbian's Korean autonomous prefecture and Longdong Village, Jilin Province, he was busy using the new drone to gain weight for rice. "Now a piece of rice fields can earn two money!" Lin Zhongkui, 63, said with a smile.

However, in the past, every household had a few places, small scale and extensive planting, and had good rice but could not sell it well. In recent years, the two committees of Guangdong Village have led the folks to change the breeding of rice. "This year is a new variety, and the rice is thick. I just signed an order of 20,000 pounds yesterday." Lin Zhongkui pointed out not far away, and there was a column of red train stopped in the field. Second money. "

Guangdong Village is only 90 kilometers away from Changbai Mountain, and the advantage of developing tourism is obvious. The northeast winter is cold, and the tourism is clear during the peak season. "All are rural tourism, where is our village especially?" In 2011, Yang Lina, the chairman of Gwangdong Village Guixin B & B Professional Cooperative, returned to his hometown to start a business. She aimed at the advantages of the local rice fields and cooperated with the large grain farmers in the village. Without affecting planting, she innovatively launched tourism projects such as rice field painting and rice breeding experience. "At the end of the year, the village is divided in proportion, and no busy villagers can also come to help the workers." Yang Lina introduced. As of now, the cooperative has led more than 500 villagers to increase their income by exceeding 3 million yuan.

In 2018, Yang Lina tried to sell villagers by online malls. "The sales are wide, and the consumption chain of tourists has also been extended." Immediately after, Guangdong Village successively launched projects such as waterfoods, rice parks, and village history museums. Last year, it attracted more than 500,000 tourists, with a per capita net income of over 16,000 yuan, and a collective income of village nearly 400,000 yuan.

Near the evening, Lin Zhongkui returned home from the field. The family discussed the decoration plan of the house while eating.

Improve the ecology and build a national park

Reporter Zheng Zhiwen

A heavy rain just passed. In the depths of dense forests in the northeast tiger and leopard national park, the soft soil, the Siberian tiger footprints were clearly visible. "Looking at this footprint, a Siberian tiger should just leave." After the rain, Li Dongwei, the captain of the Patrol Team of the Forestry Bureau of Jilin Province, and the team members often gained new gains.

The living state of the Siberian tiger is an important indicator of the local ecological environment and ecological balance. In recent years, wild Siberian tigers have frequently appeared in eastern Jilin, marking that the local ecological environment has continued to improve.

In 2017, the Northeast Tiger and Leopard National Park carried out a pilot system. In 2021, the Northeast Tiger and Leopard National Park, which across Jilin and Heilongjiang, was officially established. The latest data show that the number of wild Northeast Tigers and Northeast Leopard in the park has risen from 27 and 42 at the beginning of the pilot to 50 and 60 respectively. "Since the pilot, great changes have taken place in the Northeast Tiger and Leopard National Park." Feng Limin, deputy director of the Northeast Tiger and Leopard Monitoring and Research Center of the National Forestry and Grassland Bureau, said that there are currently stable activities in tiger and leopard population in the park with more than 50%of the parks in the park.

In order to strengthen the construction of national parks, Jilin Province strengthened the authenticity and integrity protection of the natural ecosystem, strengthened daily patrol monitoring, carried out special law enforcement actions in accordance with the law, and provided guarantee for the free habitat of the Northeast Tiger and Leopard. "In 2015, Jilin Province planned and constructed a highway and a high -speed railway. Once planned according to the original plan, it will cross the wild northeast tiger and leopard inhabitation and migration hotspots." Feng Limin looked in his eyes and was anxious. Make suggestions to Jilin Province that the ultimate economic interests are the ecological ways, protecting the road for tiger and leopard, and the planned highway cancellation, and the high -speed railway is diverted.

The forest is lush and vibrant. This year is the tenth year of Li Dongwei who is engaged in patrol work. He said with emotion: "In the past ten years, forests have become more and more dense, more and more animals, and tiger and leopards are back. I hope that this can truly become their paradise."
