Inventory Of 60 Major Inventions Of New China (Six)

4. Li Guokun: pull push magnetic circuit theory

Introduction: according to traditional theory and practice, magnetic experts generally believe that rare earth permanent magnets can not depend on each other, that is, disperse magnetic circuit. Professor Li Guokun has studied rare earth permanent magnets for more than 40 years, and thinks that the characteristics of the rare earth permanent magnet will not depend on magnetic demagnetization. The advantage is that with the same volume, the magnetic force will increase to 3 to 4 times. Li Guokun invented the theory of pull push magnetic circuit, which is mainly used in petrochemical industry and environmental protection engineering field.

Impact: according to our understanding, Professor Li Guokun first proposed the theory of "pulling the magnetic circuit" in the world. It is known as the "Li's pull magnetic circuit" and enjoys a world-renowned reputation. Based on this theory, the all permanent maglev wind and solar complementary power supply system makes full use of natural wind and solar power, abandons the traditional power supply, and does not rely on consumption of fossil fuels such as coal, thereby reducing air pollution and achieving zero electricity and zero emissions. If the house is repaired in the open field, it can also be used for lighting, watching TV and surfing the Internet at any time. As long as we have a novelty on top of the door, we can easily handle it.

5. breeding of self incompatible lines of cabbage and seven new varieties formulated

Brief introduction of the invention: 1985, according to the characteristics of cabbage's extensive self incompatibility and the genetic principle of heterosis, the method of continuous selfing, isolation, identification and directional selection was used to create the "cabbage white cross incompatibility line" and the seven series of new varieties formulated. It solved the technical problems of the breeding of the self incompatibility line of cabbage and the generation of hybrid seeds. The theory and practice of cabbage breeding in China have reached the international advanced level.

Effects: the research on breeding methods of self incompatibility lines and seed production techniques of the first generation of Brassica oleracea L. is at the leading level in China. Increasing production and income is the largest variety of Gan Lanxin varieties with the largest planting area, the most widely adapted area and remarkable economic benefits. It has opened up a new prospect for large-scale application of hybrid seeds in vegetable production in China.

6. China circulation No. 1 (HL-1)

Brief introduction of the invention: in September 21, 1984, the experimental device of controlled thermonuclear fusion designed and constructed by the Southwest Physics Institute of the Ministry of nuclear industry, China circulator No. 1 (HL-1), was successfully launched and passed through inspection in the outskirts of Leshan, Sichuan province.

Impact: the development of circulator No. 1 marks the new development of device construction and experimental methods in the field of controlled thermonuclear fusion research in China, laying a good foundation for future physical experiments.

7. Zhang Yuchun: precious crystalline glaze

In September 1987, at the third national invention exhibition, Zhang Yuchun, the Tangshan City Ceramic Research Institute and other comrades successfully developed the "iron red gold ring crystal glaze double ear bottle", which attracted the attention of the audience. This kind of glaze, the bottom glaze is sea cucumber brown, showing beautiful red flower gold ring and yellow green crystal flower on the surface. It has seven kinds of colors, colorful and elegant. Its unique Oriental beauty and mysterious charm make people yearn for love.

Influence: the crystalline glaze of the iron red gold ring is the same kind of hetero crystal of the enamel enamel. Its appearance is enough to prove that the firing technology of the enamel enamel glaze that used to be regarded as "divine skill" has been unveiled by the modern skilled craftsmen, and the precious colored glaze that has been lost for more than 700 years appears on the land of Shenzhou. Zhang Yuchun not only inherited the traditional skills in the past, but also made innovations. After the ministerial level appraisal, the experts considered that it was the artistic treasure created at home and abroad. When a variety of crystalline glaze products produced by this process were exhibited in countries such as the United States, Japan, Hongkong and other countries, the overseas ceramic industry was sensed. They called it "ceramic treasure", which is called "the national treasure that can be met and cannot be sought".
