Inventory Of 60 Major Inventions Of New China (Three)

9. our first batch of Jiefang cars

Introduction: in July 13, 1956, the first batch of Jiefang car was successfully produced in the first automobile factory of Changchun.

Impact: the world's first car was born in 1885, and soon the car spread to China. Before liberation, on the highway in China, like the "Wan Guo Auto Exhibition", there were more than 130 different brands of cars, but none of them was made in China. The release of Jiefang car ended the history of China's inability to produce cars.

10. the first atomic reactor

Introduction: in June 30, 1958, the first experimental nuclear reactor in China was officially operated. Nuclear reactor is a device to split nuclear nuclei and maintain chain reaction. It is the main form of energy utilization in the nucleus. The newly built nuclear reactor in our country is heavy water and its thermal power is 7000 L, 000 kilowatts. Its main purpose is to carry out scientific research and manufacture of isotopes. It uses uranium as fuel and heavy water as moderator and heat conducting agent, so it is called an experimental heavy water reactor. In the afternoon of June 13th, the reactor began chain reaction and gradually increased its power.

Impact: in June 30, 1958, Xinhua reported that the first experimental nuclear reactor in China has been officially operated, and the cyclotron has been built and is preparing for scientific research. This indicates that China has entered the era of atomic energy.

I. 1960~1969

1. synthetic bovine insulin

Introduction: in September 17, 1965, Chinese scientists first synthesized crystalline bovine insulin by artificial methods in the world for the first time.

Impact: This is the first human synthetic protein that has been produced in life. In the past, the world generally believed that life bodies were natural. Most of them believed that artificial synthetic life was impossible. The Chinese made it possible for the first time. The synthesis of artificial cow insulin marks a crucial step in understanding the life and exploring the mysteries of life.

2. China's first transistor computer

Brief introduction of the invention: in the case of technical blockade abroad, no precedent in China, and unstable performance of domestic transistors, at the end of 1964, Kang Peng development group finally developed the first universal transistor computer 441-b-i computer in China with domestic semiconductor components.

Impact: in February 1965, the aircraft went through continuous operation for 268 hours without any fault, and its stability reached the international advanced level at that time. At the end of 1965, they developed the 441-b- II computer. The "441-b" of Harbin military engineering is not only China's first transistor computer, but also China's first independent innovation and industrial mass production computer. It is used in "two bombs and one star", annihilating six, Navy, air force, Second Artillery, and China Telecom, Daqing oil field, etc.

3. two bombs and one star.

Introduction: "two bombs and one star" initially refers to atomic bombs, hydrogen bombs and man-made satellites. "In October 16, 1964, the first atomic bomb exploded in China. In June 17, 1967, the first hydrogen bomb test was successful. In April 24, 1970, the first man-made satellite was launched successfully. This is the human miracle created by the Chinese people in the journey of climbing the peak of modern science.

Impact: the older generation of scientists led by Deng Jiaxian selected more than 20 newly graduated college students to work day and night under the vacuum of lack of information, and finally lit the magical fire over the Gobi beach in Lop Nor to produce the "mushroom cloud" peculiar to the atomic bomb. After the successful development of the atomic bomb in two years and eight months, the hydrogen bomb was successfully studied in 1967. From the atomic bomb to the hydrogen bomb, the United States used the seven years and four months, the former Soviet Union used four years, Britain used four years and seven months, France used eight years and four months, China only used two years and eight months. This shows that China's nuclear technology has ranked the highest in the world. In April 24, 1970, China's first man-made earth satellite, "Dongfanghong" 1, was successfully launched, making China the fifth country in the world to successfully launch satellites with homemade launch vehicles after the Soviet Union, the United States, France and Japan. Without launching satellites, China could not be called a big country with important influence, and would not have such an international position.
