Inventory Of 60 Major Inventions Of New China (Five)

6. artificial satellites

Introduction: in April 24, 1970, China launched the first artificial earth satellite launch and successfully sent the first satellite into orbit.

In March 3, 1972, second scientific and technological test satellites were launched in China.

In November 16, 1975, China's first recoverable remote sensing satellite was successfully launched.

Impact: Since 1950s, mankind has launched about more than 5000 man-made spacecraft, most of which are man-made earth satellites.

In 1970, China launched the first man-made earth satellite, Dongfanghong I, whose satellite quality surpassed the sum of the first man-made earth satellite in the Soviet Union, the United States, France and Japan. This shows that China's satellite technology has a high starting point.

Three, 1980~1989

1. supercomputer "Galaxy - No."

Introduction: in 1983, our country successfully developed a giant computer "Galaxy - No.", which accelerated the development of national informatization.

Influence: Tso Yun Gui served as the chief commander and chief designer of this task.

They make full use of the favorable conditions of opening up to design the overall plan of China's 100 million supercomputers, which is compatible with China's national conditions and is compatible with the mainstream international mainstream.

In the exploration of new technologies, new technologies and new theories, the "galaxy" 100 million supercomputers have developed creatively in 10 aspects, filling the gap of domestic supercomputers, making China one of the few countries in the world with giant computers, and widely applied in petroleum exploration, weather prediction and engineering physics research.

2. test tube goat

Brief introduction of the invention: in March 9, 1984, our young scholar, sun Xu, worked with Japanese scholars to produce the first "test tube goat" in the world. In March 10, 1989, the first test tube sheep (also the first test tube animal) of our country weighing 5.3 kilograms was born. In August 15th of that year, the first test tube cattle in China was also successfully delivered.

A year later, they delivered the world's first fetal frozen thawed embryo pfer "test tube sheep".

Impact: this series of major scientific research results again aroused strong repercussions at home and abroad, and also brought great joy to the rising sun.

It indicates that China's research in this field has entered the world's advanced ranks.

The significance of these results is that they can provide high-quality, low-cost, mass embryos for commercial embryo pfer, accelerate the breeding speed of good livestock, and provide the possibility for embryo segmentation, sex control, nuclear pfer, gene pfer, etc., and have broad application prospects in reproductive biology and animal husbandry.

3. Wang Yongmin: five stroke font input method

Introduction: the five stroke input method was invented by Wang Yongmin in August 1983.

Impact: in five years of research and invention, it was evaluated by experts at home and abroad as "five stroke font" whose meaning is no less than that of movable type printing (Wang Ma). With the application, integration and creation of the latest achievements in multidisciplinary research, the "three principles of shape code design" was put forward. The "Chinese character root periodic table" was first created, and 25 key 4 yards efficient Chinese character input method and word compatibility technology were invented.
