China's Own Core Software for GIS

Thanks to their 3-year efforts, the scientists of Chinese Academy of Sciences have successfully worked out SuperChart 2000, a new system software platform for geographic information system, which has made China reach the world advanced level in the area and break the monopoly of imported products over its domestic market.

Being an coordinating institution and industrial development base for CAS' geog raphic information business, CAS' Geographic Information Industrial Development Center and Beijing SuperChart Geographic Information Technology Co. Ltd. have jointly developed this sophisticated system software platform. Applied with the unique massive data storage and displaying techniques and rich-space informationp rocessing functions, the platform has proved the strongest of its functions among its international counterparts.

SuperChart 2000 is an open ended system allowing users to work on professional software products of independent intellectual property rights that can be mixed into other information systems, providing geographic information. While developing geographic information system, it may serve the role as a computer chip. The platform is good for the secondary development, on which scientists have developed numerous professional software. The system has find perspective applications in China's Civil Aviation Administration and became the substitutes of the imported one in a dozen of projects.

Marine Configuration and Terrain Sounding Technology 

Thanks to their 4-year efforts, Chinese experts and researchers have completed the studies of marine configuration and terrain sounding technologies, a project under the National 863 Program. They have worked out the solutions to five major difficulties such as accurate marine terrain and landform sounding and in-depth marine crustal structures sounding, and developed 9 innovative technologies and 6 innovative products in the course of studies.

Focused on the possible areas for breakthroughs such as highly accurate multiple wave full area sounding, side screening and deep visual imaging, dual-boat seismological and crustal sounding, the system was integrated with many advanced techniques such as marine floor terrain sounding, side scanning imaging, accurate navigation and positioning, high resolution seismological sounding, dual boat refraction/wide angle reflection seismological reaction, 3-D seismological analysis and imaging, dynamic marine based land mapping reference and other techniques relating to imaging, model identification, automatic graphic system and intelligent interpretation. These developments have stimulated the studies of marine geographic survey techniques and made them reach the internationally advanced level in the 1990s. On the basis of technical experiments over typical marine areas,the optimized sounding technology integration, graphic and displaying integration and intelligent interpretation integration were developed, which provided high tech support for the special studies of China's continental shelf and special economic zones and important scientific evidences for marine demarcation, marine rights
protection and marine resources assessment. The accurate full marine terrain and landform sounding system developed in the studies has put a period to the history that China was unable in the past to carry out large and medium scale ocean floor geographic survey. In the meanwhile, other systems developed such as multiple wave depth sounding, deep side scanning and differential GPS navigation system have made China able to accurately map 3-D marine terrain at a scale of 1: 100,000 and 1: 1,000,000 over an range of 800 km with 10 m positioning accuracy.

At present the said technologies and results have been successfully applied in China's survey over its special economic zones and continental shelf and multiple metal nodules mines prospecting over the Pacific Ocean, bringing about remarkable social and economic benefits. The diffusion and application of multiple wave in-situ data quality control alone has saved the costs of RMB 10 million with working efficiency improved by 30%-50%. In addition, many other new technologies were used in the survey of national land and mineral resources and national territory mapping. The applications of the technologies have led to the discovery of a number of seismological refraction to the marine air-hydrates over Xisha marine trough of South China Sea and laid a foundation for the further prospecting of China's natural air-hydrates resources.

Pilot Experiment on Genetically Modified Carps

The studies of the Yellow River carps genetically modified for fast growth chaired by Zhu Zuoyan, academician of Chinese Academy of Sciences (CAS) and a research fellow of CAS' Institute of Aquatic Living Creatures have screened out 200 fine Yellow River carps genetically modified for fast growth who recorded a growthrate of 140% faster than that of the comparison group. Experiments have shown that the eggs conceived by genetically modified carps are lower than that of unmodified Yellow River carps in volume though without much difference in fertility and hatching comparison. The genetically modified Yellow River carps have demonstrated strong reproduction capability. The so-called F-1 generation of the new species has not only increased the yield but also reduced the breeding costs and provided the evidence for further screening out better modified species. Its triploid species have recorded an increased growth speed by 15% against that of the comparison group and feed efficiency improvement by 11.1%. The studies have led to the efficient and safe breeding mode for genetically modified carp species. The experiments have also shown that the mouse who ate genetically modified fish has shown no implications on their growth, organ development, blood physiological in dicators, reproduction capacity and the growth and development of their following generations.

Rumen Micro-organism Urase Depressor

Not long ago the research on the synthesizing and applications of rumen microorganism urase depressor, a project financed by Chinese National Natural Science Foundation and chaired by Dr. Wang Jiaqi of the Institute of Animal Husbandry, Chinese Academy of Agricultural Sciences has successfully turned out urase depressor applicable to animal husbandry production on the basis of Chinese scientists' three-year painstaking efforts.

It is reported that Chinese scientists have not only extracted the highly pure urase depressor through artificial rumen approach, the first of its kind in the world and measured its physical and chemical properties and determined the elements affecting the urase activity, but also revealed the dynamic relationship between the rumen urase depressing and urase functions. The techniques for synthesizing urase depressor have also been worked out in the lab environment, landing a synthesis efficiency over 60% and purity 80%. The application of urase depressor may slow down the urea decomposition by 55.3% and increase the application efficiency by 16.7%.

Extensive breeding experiments have shown that the application of urase depressor may increase milk produce by 15% and daily beef produce by 18% recording an input-output ratio between 1:3 to 1:8. The successful synthesis of urase depressoris of positive implications on replacing protein feeds with urea, addressing the problems of low urea utilization by beef, cows, sheep and deer, easing the shortage of protein feeds in the country, promoting the feed industrial development for ruminant animals, restructuragricultural structures, stimulating the development of rural economy and increasing farmers' income.
