The result of the experiment showed that the fittest C/N ratio is 131 and the production of mutanolysin can be increased 2.45 times by adding up the inducer S. mutans cell into the liquid medium. At the same time the production was also affected to a different degree by feeding of surfactant and antifoam agent...

结果表明，最适C／N比为13∶1，培养基中加入诱导物变形链球菌菌体细胞，变溶菌素的产量可提高2.45倍，表面活性剂及消泡剂等的加入对变溶菌素的产生都有不同程度的影响，Tween20和植物油均可促进酶的产生。

It is now well understood that asparagine synthetase is composed of two parts: a wedge-shaped place in the two antiparallel β-overlapping layers near the N-terminus that functions in glutamine hydrolysis; a C-terminus responsible for binding of Mg2+ ATP and aspartate.

现又明确天冬酰胺合成酶是由两部分组成：N基末端的两个反平行式β-折叠片层中的楔形部分是负责水解谷氨酰胺的活性部位；C基末端负责结合Mg2+ATP和天冬氨酸。

Lastly, we study a model of the heat flow cryptosystem base on a linear pseudoparabolic equation. The C-N difference scheme arithmetic of the encryption and decryption problems is designed. Then the numerical simulation is done through computer programming. So by analysing the simulation data we deduce many regularly conclusions on the influence of the key functions to the encryption and decryption operations, which establish the theoretical base for the application of this cryptosystem.

最后，文章研究了一类基于线性伪抛物型方程的热流密码体制模型，设计了加、解密问题的C—N差分算法并通过计算机编程进行了数值模拟，得出了一些不同密钥函数对加、解密作业影响的规律性结论，为该密码体制的现实应用奠定了理论基础。

Similarly, the addition of any three natural numbers must satisfy associative law:+c=a+, and then we can verify that for any n natural numbers, the results of adding is the same in any associative way which keep the order of numbers.

类似地任何三个自然数可以有结合律：+c=a+，进而可以证明任何n个数的任何结合方式进行加法所得的结果是一致的。

To meet the needs for scientific, technological and socio-economic development in China, we proposed the four areas that the Chinese scientists should focus their study of global change and terrestrial ecosystems in future, including:(1) Metabolism and coupling mechanism of key life elements in terrestrial ecosystems in China;(2) Implications of terrestrial ecosystems in areas sensitive to global change and in important transects on global change;(3) Interactions between biogeochemical cycle of C, N, P, S in China and global change; and (4) Development of regional dynamic vegetation model which meets the actual needs of China.

中国学者在全球变化与陆地生态系统研究领域也开展了许多工作并取得了重要成绩。按照我国科学技术和社会经济发展的需求，本文提出了未来我国在该领域的研究重点，包括（1）中国陆地生态系统重要生命元素的代谢及其耦合机制研究；（2）全球变化敏感区域或重要样带上陆地生态系统对全球变化的影响研究；（3）我国的C、N、P、S生物地球化学循环与全球变化的关系研究；（4）发展中国特色的区域植被动态模型。

Results The serum antibody level reached to 0.71±0.08-0.77±0.06 after genetic vaccine pCD-HCV1(100 μg/mouse) were inoculated into the mice(n=12) three or four times while blank vector pCD-SRα1 could not induce the mice(n=8) to generate antibody response in same way.After the antibody levels in mice(n=8) immunized by pCD-HCV1 had ascended to peak value(0.71), there was no trend of descending during the following 18 weeks of detection(0.68±0.06-0.75±0.07). Specific fragment of HCV cDNA identified by polymerase chain reaction from DNA extracted from the muscles of the mice after pCD-HCV1 had beed inoculated three months.
