The electronic structures of Dawson anion(S2Mo18O62)4- have been calculated by the discrete variational method coupled with the first principal density functional theory.And the comparison with Keggin anion(SMo12O40)2- has been made.The results show that the electrons delocalize around the all anion.But the difference of the electronic distributi on of polar and equator sites exists.

使用第一原理密度泛函理论中的离散变分方法对（S2Mo18O62）4-的电子结构进行了理论计算，并与Keggin结构（SMo12O40）2-的电子结构作了比较分析，结果表明，（S2Mo18O62）中的电子离域地分布在整个阴离子骨架中，但极位和赤道位原子的电荷分布有明显差异。

The experimental values of the critical concentration were in agreement with the calculated ones based on the Khokhlov-Semenov-Odijk theory, which indicated that the lyotropic behavior of chitosan in dichloroacetic acid can be well described with wormlike chain model.

临界浓度的实验值与根据Khokhlov-Semenov-Odijk理论预示的值比较一致，说明蠕虫链模型可以很好地描述壳聚糖分子链在二氯乙酸中的溶致液晶行为。

The article selects the most discussable part to study comparatively.

而船舶优先权是船舶物权中争议最多的领域，故笔者采用比较的方法分析研究，以船舶优先权为主线，从船舶优先权与船舶抵押权和船舶留置权的对比中更深入地对船舶优先权从多角度浅作探讨，并提出自己的若干观点或建议，同时希望能起到抛砖引玉的效果。

A new way to classify wireless sensor networks based on feasibility of anchor nodes disposing is put forward.A representative nodes localization arithmetic of the networks that anchor nodes are disposed dispersively in all of it,the one that anchor nodes can only be disposed in the edge of it and the one in which anchor node can't be disposed,is summarized,and expatiate,and then the localization algorithms fit for the three kinds of networks are compared and estimated.

从锚节点可部署程度出发，提出了无线传感器网络的一种新的分类方法，系统地总结、阐述了锚节点分散部署于整个监测区域和只能部署于监测区域周围以及不能部署锚节点的3种网络可采用的代表性节点定位算法，并对3种网络的定位算法作了比较和评价。

Because constructing the fuzzy function is aim at every target of financial risk dividedly, the fuzzy function constructed has target and is a quantitative member belongs to [0,1]. Thus the constructing of function has more objective, and better reflect the unified target .

因为构造出的模糊函数是分别针对金融风险的每一个目标的，这样构造出的模糊函数带有目标性，且是[0，1]区间的一个量化数，这样函数的构造就比较有针对性，且更好地反映了目标化的统一。

By this means the ultimate load of eccentrically compressed reinforced concrete members under different temperature can be calculated comparatively accuracy and it is verified by the experiment data.

And the enantiotropic diversity of the economy and politics between Sino-America relationship and the compound multiplicity of the national relations were reveled. Thus provided the theoretic supports for setting the strategies for the development of Sino-America economy and trade.3. From the point of view of stratagem, policy and measure, studied the countermeasures of Sino-America economy and trade in the new century in the third part of this paper.

同时，比较系统地从冷战意识和社会制度差异、思想文化和意识形态差异、双方所处国际地位的不同及美国国内政治斗争等几个方面，分析了中美经贸障碍产生的复杂性，揭示了中美经贸关系中经济与政治互动的多向性和国家关系的复合多重性，为新世纪确立发展中美经贸关系的对策找到真正切入点提供理论支撑。

And multiple effects of AK auto Ab on ker-atinocyte and possible mechanism of AK auto Ab on recovery of epiderm injury are preliminarily studied.

以往对AK auto Ab在表皮发育、皮肤损伤等过程中的作用大多从动物整体水平进行研究［2，3］，为了进一步明确AK auto Ab在表皮自身稳定中的作用，我们以体外培养皮肤为研究对象，直观地比较不同浓度AK auto Ab对表皮形成的影响，并为阐明AK auto Ab促进皮肤损伤恢复的机制进行初步探讨。

Roughness, surface crust, erodible fraction, stubble and time of efficacy are the indicators for appraisal. Results show that herd grazing has worst effects on soils; plowing is positive to the soils with lower erodibility and negative to sandy soils.(4) Prediction and control of wind erosion are the end of research. Two famous prediction models WEQ and WEPS were briefly introduced. On the basis of summarizing general theory and methodology for wind erosion control, some key measures are suggested for the region of Ningxia.
