World First Circular Permanent Magnet for Crystal Growth
The world’s first circular permanent magnet for crystal growth recently came in
to being at Hebei Polytechnic University, which is deemed a major breakthrough in addressing the oxygen concentration problem in manufacturing single crystal silicon; hence China has made a great leap in single crystal silicon manufacturing.
Along with the steady improvement of integrated circuits, the expansion of chip face has called for single crystal silicon (a raw material used for making the chip) of a larger diameter. In 1996, the project of permanent magnet simulation for silicon crystal growth under microgravity and oxygen control mechanism undertaken by Prof. Xu Yuesheng of Hebei Polytechnic University was granted with the funding support by the National Natural Science Foundation and Hebei National Science Foundation. Thanks to their 4year painstaking efforts, the research teamheaded by Prof. Xu have worked out a unique circular permanent magnet of stable magnetic field with the matching software for PM magnetic field analysis. The team also developed the first PM direct pulling oven for single crystals and control techniques for the single crystal silicone growth under microgravity and at different levels of oxygen concentration.
The evaluation committee chaired by Liang Junwu, academician of the Chinese Academy of Engineering believed that the achievement is of China’s own intellectual property rights, positioned in the world advanced. The PM produces no water and electricity consumption nor noise and therefore it is of a bright industrilization prospect.

With its successful development China has ranked among the internationally advanced in the field. In the meanwhile, the achievent is import in promoting the development of the discipline “Aeronautic Propulsion Theory and Engineering” in the Academy.
China’s Major Breakthrough in Rice Gene Separation
Chinese scientists have successfully separated nearly 2000 rice cDNA sections and developed a rive gene chip of unique functions, the first of its kind , by adopting a unique gene separation technology. The socalled MEST technique developed by the research team headed by Prof. Li Debao of the Biotechnology Institute of Zhejiang University has recently been granted with the patent protection by the China National Intellectual Property Right Bureau.
Prof. Dong Haitao of the research team said that the results of extensive experiments have shown that the said technique is able to accelerate the full length cloning and identification of rice cDNA at a large margin, which in turn greatly improves the experiment efficiency and remarkably reduces the input needed by gene cloning.
The first rice gene chip produced by using the technology has proved able to test the variations of genetic expressions and realize the analysis of biological events such as drought, cold and diseases resistance of rice at the genetic level.
Dong added that at the present stage they have cloned a group of genes relating
to triggering the bacterial leafblight of rice by adopting the gene chip technology. He said that in a short period of time they will use the rice gene chip system to make MEST sequencing data available to the public both at home and abroad. In the meanwhile, they will clone several new genes relating to rice resis
tance to both adversities and diseases and establish a service platform for rice
gene research communities.
Obtaining major genes working on rice agricultural properties such as diseases resistance and yield increase is very important in new pesticides development and
selection, environment protection, improvement of rice quality and screening out the rice species of high yield and diseases resistance.
Dong expressed that the technological revolution taking advantage of existing biological information and human genome projects will accelerate the pace of cloning genes with major agricultural properties and implementing rice genome project, which represents opportunities as well as challenges facing the Chinese scientists working on rice molecule biology. At the beginning of the year, the Research and Development of Rice cDNA Gene Chips Classified by Protein Modules and associated projects were financed by the Ministry of Science and Technology, National Natural Science Foundation and Zhejiang Provincial Department of Science and Technology.
