A human model using polynomial convolution surface is presented which is modeled by articulated skeletons convolved with some kernel function. The convolution surface and curve correspondence theorem under orthogonal projection is presented. The human contour is approximated with a convolution curve and 3D human pose can be estimated using a nonlinear optimization algorithm.

首先建立了一种新颖的多项式密度卷积曲面人体模型，该模型由连接体线骨架与某种卷积核卷积而成，整个曲面是一张连续曲面，调节多项式和半径参数可以让人体任意变形；给出了正交投影下卷积曲面和曲线对应的概念和相关定理，为二维的图像轮廓和三维人体模型之间建立对应关系；根据正交投影下卷积曲面与曲线对应定理，用卷积曲线去逼近人体的图像轮廓曲线，从而估计和恢复出三维人体运动姿态。

The article studied Eisenberg model, Forsman model, Dreyfus model, Bonnoto Bonner, Longworth, Vaughan model and Core-shell model. A BAB-triblock copolymer was employed as macromolecular model. Minimized Gibbs free energy relates the micellar structure parameters to parameters of the triblock copolymer quantitatively. Furthermore, it could be explained theoretically that the micellar diameter and the equilibrium aggregation number both decrease with ion content.

然后讨论了BAB型三嵌段模型、Eisenberg模型、Forsman模型、Dreyfus模型、Bonnoto和Bonner、Longworth和Vaughan模型与核-壳模型，并以BAB型三嵌段离聚物为模型大分子，建立了胶束特征参数与聚合物结构参数之间的定量关系，从理论上解释了胶体粒径和聚集数随离子含量的增加而降低的原因。

Then,the core molecule was used as a coupling agent to condensate with polyethylene glycolsof different molecular weight or polyethylene glycol monomethyl etherin the presence of stannous octoate as catalyst and diphenyl ether as azeotropic agent to remove water.

在辛酸亚锡催化下，以二苯醚为共沸脱水剂，将三官能度小分子TMP-SK3作为偶联剂，进一步与不同分子量的端羟基聚乙二醇和聚乙二醇单甲醚缩合，减压下共沸脱水，制备了以TMP-SK3为核，PEG或PEGm为臂的三臂星形大分子。

In chapter Ⅲ, heteronuclear three-dimensional spectroscopy methods were used to determine the structure of a protein of 99 residues.

在第三章中，我们通过异核三维谱的方法研究了一个近100个残基的蛋白质的结构。

Pyriformis. The half maximal inhibitory concentration (IC50) of melamine, changes of T. pyriformis cellular morphology and alterations of T.

三聚氰胺对梨形四膜虫的半数抑制浓度IC_(50，梨形四膜虫的细胞形态及细胞内蛋白质表达含量的变化是本次三聚氰胺对真核细胞毒性研究的重点。

Mao once sanguinely contemplated a world after a full-scale nuclear war with the comment that if one-third of mankind would be killed, the other two-thirds would be socialist.

毛曾经冷酷地思考过全面核战之后的世界，死掉三分之一的人类，剩下的三分之二将是社会主义者。

This is transformed into anomeric acetates 16, which is used for the synthesis of a number of 2＇, 3＇-dideoxy-2＇-trifluoromethylnuclosides via Vorbruggen glycosylation reaction. At the same time, L-2-tifluoromethyl-4-thiofuranosides 39 were also prepared from the key intermediate lactone.

从这一砌块出发，经由关键中间体2-三氟甲基-γ-丁内酯转化得到的化合物16的Vorbruggen糖苷化反应，合成了2＇，3＇-双脱氧-2＇-三氟甲基嘧啶核苷。

The primary function of reactor protection system is to protect the integrity of the three nuclear safety barriers, namely, fuel cladding, primary pressure boundary and containment. When the certain safety limits, determined by the accident studies, are exceeded, The reactor protection system will give the protection signals of reactor trip and/or safeguard actuations, and then the reactor trip system and/or the engineered safety features are actuated.

反应堆保护系统的功能主要是保护三道核安全屏障(燃料包壳、一回路压力边界和安全壳)的完整性，当运行参数达到危及三道屏障完整性的阈值时，保护系统动作触发反应堆紧急停堆和启动专设安全设施。

Three wheat spindle streak mosaic viruses resistant cultivars ('Yining Xiaomai', 'Xu87-633', and 'Xifeng') and one susceptible cultivar ('Zhen9523') were used as parents of 3 crosses in this experiment. WSSMV resistance of the parents, F1, and F2 was evaluated under field condition.

选用3个抗梭条花叶病的小麦品种&仪宁小麦&、&徐87-633&和&西风&为抗病亲本、以感病品种&镇9523&为感病亲本配制了三个杂交组合，对四个亲本及其杂种后代（F1及F2代）单株的田间抗病鉴定表明，三个抗病亲本的抗性均由核基因控制，为显性遗传方式。
