China's Heyday for Astronomical Studies

It is reported from the first academic conference of Chinese Astronomy Society held not long ago that the Chinese central authority has started from 1997 doubled its investment in astronomical studies, which has developed a historical heyday for the field, witnessing a series of major breakthroughs.

Large science projects have enjoyed smooth development. Following the completion of the preliminary design of large sky area multi-object fiber spectroscopic telescope(LAMOST) that will soon be under full fledged implementation, Chinese astronomers have now been working on the pre-studies of other two projects: solar telescope and 500-m astronomic telescope. They are the internationally class one observation instruments of innovative concepts and touches.

Of them, China's first 1-m solar telescope is expected to be launched into space in the first decade of the new century and become the largest astronomical satellite in the world.

A group of major observation systems have been completed one after the other. In collaboration with Australian and British scientists, Peking University, Wulumuqi Observatory and Hong Kong University have established
pulsar observation base through developing multiple-frequency pulsar observation instruments of internationally advanced accuracy at microseconds on the basis of 25m astronomical telescope of Wulumuqi Observatory. Shanghai Observatory has developed satellite based daytime laser rangers which are able to range the distance of satellites even under the strong noon sunlight with internationally advanced accuracy and won national S&T advance prize last year.

Chinese scientists have, through technological innovation, harvested a number of important astronomical discoveries. Beijing Observatory has turned a 60cm telescope into an intelligent supernova observation instrument which helped the Observatory discover 35 supernova displaying restless movement in the galaxy in 1997. In the meanwhile, other observatories have laid an extensive net to catch the small planets that may possibly hit the earth. Of the small planets discovered by Zijinshan Observatory, 142 have been given official names. In addition, Zijinshan Observatory has also discovered four comets. Beijing Observatory has discovered 175 small planets, which have been officially named. Zijinshan Observatory and Beijing Observatory have discovered some young celestial bodies such as 110 celestial bodies carrying water sources, which is of important values to the studies of planet formation.

Chinese astronomers have achieved the world eye catching theoretical research results by taking advantage of observational data available internationally, although China is still lack of large astronomical observation instruments. Wu Xiangping, aresearch fellow of Beijing Observatory has for the first in the world proposed the theory that there exists dark matter core in the center of galaxy clusters on the basis of his studies of the statistical characteristics of gravitational lens effects and the theory was reconfirmed by observations. In addition, hecreated the theoretical framework for micro gravitational lens.
Recent years have witnessed remarkable results achieved by Chinese astronomers in basic astronomical studies. Shanghai Observatory established the non-rigidearth nutation model for oceans and atmosphere, which has become one of the four nutation models acknowledged by the international communities for references purpose. The model has also drawn out China's horizontal earth crust movement chart, the first of its kind in the world, disclosing the basic characteristics of the Chinese continent movement. Zijinshan Observatory successfully predicted the fall of overseas satellites that had lost control; Shaanxi Observatory has established China's world time and atomic time reference system and long and short-wave time service system.

China's New Progress in Integrated Manufacturing System

Recent years have witnessed China's great attention paid to manufacturing technologies, especially the automation and information process of manufacturing. Since 1986 when CIMS project was kicked off under the National 863 Program, the computer based integrated manufacturing system characterized with information integration at earlier stage has been eventually upgraded to the modern integrated manufacturing system based on information integration and industrial optimization as the result of 15-year tireless efforts. At present, there are more than 200 manufacturers in the country demonstrating their modern integrated manufacturing systems applied with multiple production and operational modes on different scales. Covering a wide range of businesses, these manufacturers have been dotted over the country with their products ranging from simple ones to sophisticated ones, achieving remarkable economic and social benefits. 50 and odd products of 11 categories supported and nurtured by the modern integrated manufacturing system have taken up 85% of the software products needed by industrial information process, shaping up a new industry of an annual output value exceeding Rmb 100 million with a domestic market share of 10% and above.

It is reported that Shaanxi Province, a demonstration area for the application of modern integrated manufacturing systems has so far successfully staged the modern integrated manufacturing system in 11 enterprises including Xi'an Aircraft In dustrial Corporation, Qinchuan Machine Tools Group Co. Ltd., Xianyang Deflection Group Corporation, Xi'an Aeronautic Motor Corporation and China Standard Sewing Machine Group Co. Ltd.. The applications of advanced manufacturing technologies and information technologies in transforming traditional industries have become valuable assets for the future development of the manufacturing industry in west China.

China's New Height for Foreign Capital Utilization

During the 9th Five-Year Plan period, thanks to the tireless efforts of all economic sectors, China has shaped an opening pattern for all the fields, at multiple levels and in diversified areas.

During the period from 1996 to 1999, China had utilized foreign capital totaled USD 230 billion. It is expected that the foreign capital utilization during the 9th Five-Year Plan period will go up to USD 290 billion, landing a growth of 80% against the previous Five-Year period. Of the said capital utilization, the foreign investment in the period is expected to reach USD 230 billion, nearly double the figure in the previous period. Foreign investment has since 1993 ranked the first place among the developing nations for 7 consecutive years and the second place in the world for 6 years in a row.

During the 9th Five-Year period, China's foreign capital utilization has hit the heyday in the history either in terms of its scale or in the areas or in geographic distribution. The foreign investment absorbed in the period is expected to take up 63% of the total foreign investment absorbed by China on a cumulative basis. The foreign capital utilization in the field of banking, insurance, commerce, foreign trade and tourism will be further expanded and the middle and westsections of China are allowed to widen their areas for absorbing foreign capital,loosen the condition for setting up foreign funded joint ventures and increase the shareholding percentage of foreign investors.

During the same period, the quality of China's foreign capital utilization has been further improved with better industrial structures for foreign investment and enhanced foreign investment in manufacturing and high tech industries with declined input in real estate properties. The technical intensity of foreign investment has seen remarkable improvement. Transnationals have showed their great interest in investing in China with 400 of the 500 international transnationals having made their investment in the country.

The major achievements in foreign capital utilization made during the period has greatly promoted the national economic development. It is reported that in 1999 the added values of foreign invested industries and enterprises took up 20.7% of the nation's total and taxation payment 16%. Their import and export volume in the nation's proportion also went up from 39.1% in 1995 to 50.8% in 1999, of which the export ascended by 45.5%. In addition, the foreign capital utilization has promoted the upgrading of China's industrial structures and technical levels, stimulating the transformation of industrial management mechanism and the development in the west.
