1On May 6th, 940, Zhang Zizhong's troops were already very difficult to confront the enemy, and military points were constantly being conquered. In order to boost morale, Zhang Zizhong decided to bid for crossing the river. Everyone disapproved of the decision because of the danger.

Zhang Zizhong has made up his mind to bid in person to kill the enemy's morale. This time I went to Zhang Zizhong, in order to get rid of the usual unpretentious state, put on yellow official clothes and a collar, and went to Hedong battlefield with the bearing of "the wind is rustling and the water is cold, and the strong men are gone forever".

In the battle, due to the backward radio technology, the radio code issued by Zhang's headquarters was deciphered by the Japanese army, which led to its actions being completely mastered by the Japanese army, and the Japanese army jointly attacked Zhang Zizhong from many directions.

In the scuffle, Zhang Zizhong's men almost lost their lives. Zhang Zizhong refused to step back from beginning to end, and the guards Ma and others also protected him. In the battle between the two armies, a Japanese soldier stabbed a guard horse with a bayonet.

Zhang Zizhong glared, grabbed the enemy's bayonet and covered Ma Xiaotang with his own body. At this time, a bullet shot at Zhang Zizhong, passed through his abdomen, and another bullet hit his right forehead. A generation of famous anti-Japanese soldiers devoted themselves to serving the country and collapsed.

2. Qian Xuesen

At the beginning of 1956, Qian Xuesen put forward "Opinions on Establishing China's National Defense Aviation Industry" to the Central Committee of the Communist Party of China and the State Council. At the same time, Qian Xuesen established the first rocket and missile research institute in China, the Fifth Research Institute of the Ministry of National Defense, and served as the first president.

He presided over the completion of the "jet and rocket technology" program, participated in the development of short-range missiles, medium-and short-range missiles and China's first artificial earth satellite, and directly led the "two-bomb combination" test of medium-and short-range missiles carrying atomic bombs.

Participated in the formulation of the "two-bomb combination" test of China's short-range missiles carrying atomic bombs, participated in the formulation of China's first interstellar aviation development plan, and developed and established engineering cybernetics and systematics.

Under the leadership of Qian Xuesen,1964/kloc-0 succeeded in exploding China's first atomic bomb in June,/kloc-0 succeeded in exploding China's first hydrogen bomb in June, 967, and/kloc-0 succeeded in launching China's first artificial satellite on April 24, 970.

3. Deng Jiaxian

Deng Jiaxian (1924- 1986), member of Jiu San Society, academician of China Academy of Sciences, famous nuclear physicist, pioneer and founder of nuclear weapons development in China, has made important contributions to the research and development of nuclear weapons and atomic weapons in China.

Deng Jiaxian is the main organizer and leader of China's nuclear weapons research and development. Deng Jiaxian has been leading many scholars and technicians to successfully design China's atomic bomb and hydrogen bomb in the front line of weapons manufacturing in China.

Leading China's national defense and self-defense weapons to the advanced level in the world. 1982 won the first prize of National Natural Science Award, 1985 won two special prizes of National Science and Technology Progress Award, and 1986 won the title of National Model Worker.

1987 and 1989 each won a special prize of the National Science and Technology Progress Award. 1999 was posthumously awarded the "Two Bombs and One Satellite Meritorious Medal". Because of his great contribution to China's nuclear science.

It is called "two bombs". Deng Jiaxian suffered from rectal cancer in an experiment and died in Beijing on July 29th, 1986 at the age of 62.

4. Yuan Longping

He designed the super-high yield plant type model with high canopy, short panicle layer and large panicle and the technical route of cultivating super hybrid rice, and the research on super hybrid rice has made great progress. The research of super hybrid rice was carried out in Yuan Longping during 1997.

In 2000, 2004 and 20 12, the targets of 700 kg, 800 kg and 900 kg per mu in the first, second and third phases of China Super Rice Demonstration Film were achieved respectively.

In 20 13, the fourth phase of the research on the target of yield per mu 1000 kg of demonstration piece of super hybrid rice was started, and it is planned to achieve the target in 2020. At the same time, implement the high-yield project of "planting three crops and producing four crops" for super hybrid rice to promote the production and application of scientific and technological achievements.

Since 2007, it has achieved great results in increasing production and income, and has been implemented in seven provinces and cities across the country. Among them, in 20 12, the number of counties (cities, districts) in Hunan Province increased from 20 to 50, covering an area of 8.82 million mu.

By the end of 20 12, the accumulated demonstration and promotion area was more than 20 million mu, with an increase of more than 2 billion kilograms, which made new contributions to the sustained and stable increase of grain production.

5. Zhan Tianyou

1905- 1909 In order to develop commerce, the Qing government decided to build the Beijing-Zhangjiakou Railway. Zhan Tianyou was assigned to be responsible for road construction, first as chief engineer and general manager, then as general manager and chief engineer. This road runs from Beijing to Zhangjiakou, passing through Jundu Mountains.

The terrain is steep and the project is extremely arduous, about 200 kilometers long, which is the main road leading to the northwest. In order to compete for the right to build roads, Britain and Russia were deadlocked, and the Qing government decided to build it by itself, but it lacked confidence. Foreigners are talking about China's inability to complete the road construction project.

Zhan Tianyou said: "China has a vast territory and rich resources. It is shameful to rely on outsiders for all the work along the way!" In the face of foreigners' sarcasm, he led all road builders to face difficulties with fearless spirit. Qi Xin won glory for his country.

At the beginning of construction, there was a shortage of engineers and technicians. 1In May, 905, Zhan Tianyou led only two engineering students to survey from Fengtai via Nankou and Badaling to Zhangjiakou, then re-surveyed, selected survey from Yanqing House, and bypassed Badaling via Deshengguan.

The comparison line from the Ming Tombs to Changping (Yongding Valley route was also considered, and the project was arduous, so it could not be used due to the limitation of funds and time limit, so it was not surveyed). In June, he returned to Tianjin General Administration, put forward the investigation report and drew up the construction plan.

It is planned to be built in three parts. The first section (Fengtai to Nankou) will be started first, so as to benefit from the early traffic. The second section (from Nankou to Chadao City) and the third section (from Chadao City to Zhangjiakou) will be investigated in detail. Especially the second section from Zhongnankou to Badaling.

The terrain is steep, so further comparison lines need to be selected. The report said, "If this road becomes one day earlier, the public will benefit from it one day earlier, business travelers will enjoy its convenience one day earlier, and foreigners will envy it one day earlier; The difficulty of building roads is actually unprecedented.
