Modify the model by FreeForm software and dissecte the model of haunch bone; import the 3D visible model of haunch bone into Ansys8.0 software. Add mechanics parameter to the haunch bone model, construct 3D finite element model of acetabulum. 2、On the base of common fracture line of acetabular posterior wall fracture in clinical cases, split the acetabular 3D finite element model according to 1/3, 2/3, 3/3 areas fractures of posterior wall after simplify setting, obtain four types of acetabular posterior wall fracture model(including normal condition of acetabulum).

按髋臼骨折Letournel分类标准并根据临床髋臼后壁骨折病例常见骨折线位置，进行简化设定，依次按后壁1／3，2／3，3／3面积骨折将髋臼三维有限元模型后壁进行拆分，获得三种髋臼后壁骨折状态的有限元模型；再模拟双足直立位对髋骨约束设定，分别对后壁正常及不同面积骨折状态模型进行加载，获取各模型应力分布图并记录臼顶负重区、髋臼前壁和剩余后壁在不同后壁骨折状态下应力分布大小及改变。

Based on the biochemical analysis of the two proteins in vitro, the results of yeast two-hybrid experiment and protein-interaction in both wild type cells and C48 strain, we conclude HetR can form a homodimer through the Cys48 residue. We also show that the dimerization is required for heterocyst differentiation.

基于体外两种蛋白的性质比较和酵母双杂交的结果，并结合相应蓝细菌野生型和突变株C48A中HetR蛋白性质的体内研究表明：HetR蛋白可以通过第48位半胱氨酸残基形成共价结合的同源二聚体，该同源二聚体是异型胞正常分化所必需的。

A gentleman entered, with a pleasant, cultured face, high-nosed and pale, with something perhaps of petulance about the mouth, and with the steady, well-opened eye of a man whose pleasant lot it had ever been to command and to be obeyed.

一位绅士走过来。他相貌不凡，显得颇有教养。高高的鼻子，面色苍白，嘴角微露愠意，有着生来就有发号施令那类人所具有的一双神色镇静，睁得大大的眼睛。

She was the lady in the yellow dress, simple, bespectacled, plain not just in her housewifery but also in her demeanour, a contrast in every way to the stylish Imelda, who was still stuffing the boudoirs of the presidential palace with frocks and furs and shoes, shoes, shoes.

朴素大方的阿基诺夫人身着黄衣，戴着眼镜，看上去像一位平凡主妇，而且态度也十分谦和。这与奢侈浮华的总统夫人伊梅尔达形成鲜明对比，总统府里塞满了她的裙子、皮草和几千双鞋子。

In the fourth chapter, four new complexes of hydrazide of podophyllic acid with transition metals have been prepared. Elemental analysis, molar conductivity, IR,〓 NMR and TG-DTA were used to characterize them. The results show that general formula of the complexes is M〓(n=0 or 2). The ligand is linked through the carbonyl oxygen and the terminal nitrogen of the hydrazide base to the transition metal ions in bidentate mode.

第四章 合成了四种鬼臼酰肼的过渡金属配合物，通过元素分析、摩尔电导、红外光谱、核磁共振氢谱和热重-差热对配合物进行了表征，研究结果表明，配合物的组成为M〓（n=0或2），配体是通过羰基氧和肼基上的端氮以双齿形式与金属离子配位的。

We discover that under a general configuration the twist system of this mechanism belongs to the seventh special three-system, and all the twist axes are distributed on a hyperbolic paraboloid that is special and unusual and rarely studied. Under original configuration it belongs to the fourth special three-system.

我们发现：该机器人在一般位形下，它的所有运动螺旋轴线在空间分布的二次曲面是比较特殊的，罕见的，是过去理论上研究很少的双曲抛物面，属于第七种特殊三系，在起始位置时属于第四种的特殊三系。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.
