The radical scavenging activity of Laminaria japonica pigments was studied by the DPPH2,2-Diphenyl~(-1-picrylhydrazylassay. The total pigments showed a strong DPPH radical scavenging activity of 65.819% with the concentration of 0.52mg.ml~(-1). The DPPH radical scavenging activity of fucoxanthin was 19.85% with the concentration of 0.27mg.ml~(-1). The antimicrobial activity of pigment in Laminaria japonica was studied by the method of round paper. The results showed that the pigment extracts have activity against Escherichia coli, Pseudomonas aeruginosa, Saricina flava and Saccharomyes cerevisia. The antibacterial activity of total pigments for Saccharomyes cerevisia was the strongest with an inhibition diameter of 18.9 mm; and the antibacterial activity of fucoxanthin for Saricina flava was also much significant with an inhibition diameter of 10.2 mm.

In this paper, a method, which is based on GPS Time system, is applied to synchronize all GIBs. With GPS receiver's 1PPS output , GIB can compensate for the crystal oscillater's drift. 4. Mathematic Model of UGPS Based on the principle of hyperbola intersection, an iterative algorithm and an analytic algorithm are deduced to resolve system equations with four GIBs observations. It can also be used to resolve the approx coordinate with more than five GIBs'observations.

家庭因素在父母职业、父母文化、居住社区、是否独生四个子因素上对师范类贫困大学生的焦虑情绪产生影响，父母职业和父母文化对状态焦虑度和特质焦虑度的影响都显著，居住社区和是否独生对两种焦虑度的影响都不显著。

For example, we have conducted the sequence screening on the binding sites of the interface of Barnase/Barstar complex and found that our DGA method can not only determine which position is more conservative and more important, but also redesign the binding sites rationally. The random sequence design for α,β,α/β and α+β four folding motifs have also been practiced and revealed that there are both homology evolution and heterology evolution of protein sequences compatible the same backbone motif.

例如，通过对典型的Barnase／Barstar复合物界面研究发现，它可以确定界面结合位点的重要性和保守性，并对结合位点进行合理的序列重新设计；通过对α、β、α/β、α+β等四种折叠模式骨架的随机序列设计，发现在蛋白质进化过程中，对同一种结构模式同时存在序列的同源进化和非同源进化这两种趋势。

This paper analyzes the suitability of political party in the following five points: it expatiates on the Huntington's suitability and carries a foreshadowing of what is to follow later in the first part. In the second part, through probing into political party, it realized the general deficiency of Thailand political party. In the third part, it aims to the Thailand political ecology to analyze the military power, monarchal power and patron-client relations. It realized that the Thailand political ecology exercises a great influence on the development of political party. In the fourth part, from deducing the relationship between political party and political ecology, it realizes, it's the weak suitability lead to the military coup is inevitable. In the fifth part, it reflects further on how to strengthen the suitability of political party. It thinks that political party should have more effects on promoting the process of democratization.

本文从如下五个方面对政党的适应性进行了分析：第一部分叙述亨廷顿适应性理论的观点，给文章做了理论铺垫和假设；第二部分对政党这个政治主体进行探析，认识到泰国政党普遍存在的缺陷和不足之处；第三部分对泰国的政治生态作了分析，从军队力量、君主力量和庇护制关系等几个方面进行探讨，认为泰国政治生态对政党发展产生了巨大的影响；第四部分对政党与政治生态的关系作出合乎逻辑的推论和衡量，认为适应性不强导致军事政变等政治现象的发生不可避免；第五部分就如何加强政党适应性做出进一步的思考，认为政党在推进民主化进程中应该有更大的作为。

This paper selected 7 samples and did a series of experiments about the isochermal absorption and fixation of phosphorus to select one or several suitable crucible residue to study compound fertilizer. The result declare that the absorbed phosphorus and the fixability of the No2,Noll and No21 is smaller than the other samples,for the more the desorpability of the three samples get to 30%- 40%.

为选择合适的含硅熔渣用于复合肥，本文对含硅溶渣样品进行了对磷的吸附与解吸和对磷的固定的测定，实验结果表明，2号、11号、21号三个渣样对磷的吸附量与固定率均比其他四个供试渣样少得多，且此三个渣样解吸率达到了30％～40％。
