Inventory Of 60 Major Inventions Of New China (Seven)

Four, 1990~1999

1. Wang Xuan: Chinese color phototypesetting system

Introduction: in 1992, Wang Xuan also developed the world's first set of Chinese color phototypesetting system.

Influence: it has won the gold medal of the Geneva International Invention Exhibition, the gold award of China's invention patent, the UNESCO scientific award, the national major technology and equipment development special award and many other awards.

2. Zou Yuandong: enzymatic polypeptides

Brief introduction of the invention: in 1997, "using modern bioengineering technology to decompose protein macromolecules into small molecular peptides with molecular weight 240 - 1000, which is the short message of obtaining the smallest and most active small molecular peptide in molecular weight using enzymolysis technology in the world," has attracted much attention in the field of polypeptide at home and abroad.

Effect: "enzyme polypeptides" marks the first breakthrough in scientific research of small molecule peptides in China.

Some experts even think that "enzyme polypeptides" represent the current level and trend of peptide research, development, production and innovation in the world.

3. coconut water fermentation

Introduction: in 90s, Zhong Chunyan, a food fiber fermented from coconut water and its production method.

Impact: it is this patent that fills the gap in China and ends the history of coconut water pollution in coconut processing for thousands of years in Hainan. It also spawned a coconut industry, a unique industry in Hainan.

Today, there are more than 80 coconut processing plants in the whole province, and the output value is over 100 million yuan.

4. two-line hybrid rice technology

Introduction: in 90s, Chinese agricultural science and technology personnel used modern biotechnology to isolate and clone the photoperiod sensitive genic male sterility gene, and further developed two line hybrid rice technology using only male sterile line and maintainer line.

Impact: in the national large-scale trial production, it showed high yield, high quality and multiple resistance, and the average yield per hectare could reach 11250 kg.

5. "dawn 1"

Introduction: in October 1993, "dawning 1" large parallel computer was successfully developed.

Shuguang 1, all known as dawning, shared memory multiprocessor system.

It was the first microprocessor core developed by China in 1993.

The fully symmetrical tightly coupled shared memory multiprocessor system (SMP) composed of a chip (88100 microprocessor) has a fixed point speed of 640 million per second and a main memory capacity of 768 MB.

A series of technical breakthroughs have been achieved in symmetric architecture, parallel operation system core code and fine grained parallel multithreading technology.

Impact: it is the first parallel computer designed and developed in China for the first time based on VLSI universal microprocessor chip and standard UNIX operating system.

However, the significance of Dawning No. 1 is not only that.

Compared with the mainframe and supercomputer developed in 80s, the development cycle of Shuguang No. 1 has been shortened from the past 5-6 years to one year.

As a result of the adoption of the technological route of "doing something for nothing" and integrating with the international community, the manpower and capital invested have also been greatly reduced.

The shortening of the development cycle and the adoption of standardized technology ensure the market competitiveness of new products.

Five, 2000~2009

1. high-performance computer "Shen Wei I"

Introduction: in 2000, our country successfully developed the high-performance computer "Shen Wei I", whose main technical indicators and performance reached the international advanced level.

China has become the third country in the world that has the ability to develop high-performance computers after the United States and Japan.

Impact: its birth has declared that our country has broken the restrictions of some western countries on high-performance computers.

In the short span of 10 months, "Shen Wei Wei" has completed 28 scientific research projects, involving aerospace, pharmaceutical biochemistry, petroleum exploration and development, human gene cloning, and other fields, and has achieved fruitful application results, playing a positive role in the national economic construction.

2. Shenzhou series

Brief introduction of the invention: at 6:23 on October 16, 2003, Shenzhou 5 spacecraft.

China has become the third country to master manned space technology.

In October 12, 2005, Shenzhou 6 was launched successfully.

China has achieved a real sense of participation in space flight experiments.

In September 25, 2008, the seven mission of God as China's first lunar exploration project was a complete success.

This task will break through and grasp the key technologies of astronauts' space extravehicular activities. For the first time, astronauts' extravehicular activities and astronauts' spacewalks will make China the third country to master the technology of space extravehicular technology after Russia and the United States.

3. Li Guanqi: original fiber technology

Introduction: 2001 Li Guanqi, the world's original fiber technology with independent intellectual property rights.

After 10 years of arduous exploration, the world's eighth largest man-made fiber was extracted from the soybean oil extracted from oil, and the yarn was made into thread, spinning into cloth and dyed garments.

Influence: he made China the first original fiber technology with independent intellectual property rights in the world; he ended the absence of Chinese names in the world's invention of man-made fibres.

4. Li Denghai: Maize Hybrids

Brief introduction of the invention: Li Denghai integrated the theory of Heterosis and colony light energy utilization, and put forward the complementary point of plant type and heterosis.

More than 30 maize inbred lines with high combining ability were selected, and more than 30 compact maize hybrids were allocated.

Impact: Li Denghai was awarded the "invention and entrepreneurship Award" and the "contemporary inventor of China".

Li Denghai has produced hundreds of excellent ones.

The maize hybrid has accumulated over 1 billion 200 million mu of land to grow these excellent maize hybrids, and the yield increase effect is obvious.

He successively won the first prize of national science and technology progress, the first prize of national Spark, and the Asia Pacific Seed Association's "great contribution to China's corn industry" and other honors.
