The paper includes:The author calculate the structures inner force and displacement of the free end , analyze the influence of the height and the value of pretress of cable by making use of ANSYS 9.0 soft, pose the concept of critical prestress,conclude the function relation between displacement of the free end, initial strain and the height of cable ,analyze the dynamic properity and point out that Newmark-β method should be adopted when we analyze the dynamic properity of the cable-stayed spatial structure with direct integral test to guarantee the contribution of high mode,finally conclude the functional relation among coefficient of earthquake inner force, initial strain and the height of cable, wish to get some helpful conclusion applied to cable-stayed spatial truss design.

本文系统介绍了斜拉空间桁架竖向地震反应的分析理论与方法、详细分析了斜拉空间桁架结构在静力和竖向地震作用下的受力性能，主要内容包括：利用通用有限元软件ANSYS9.0计算了斜拉空间桁架在静力和竖向地震作用下内力及自由端位移分布规律并得出地震内力系数与节间位置、预应力以及斜拉索高度之间的函数关系；详细分析了斜拉索中施加的预应力以及斜拉索高度的变化对于该种结构内力及自由端位移的影响并提出了斜拉空间桁架的临界预应变概念，进而得到了自由端位移与初始预应变以及斜拉索高度的函数关系，即：△=-(40h+2180)ε+9.8；分析了该种结构的动力性能，并指出：在时域内采用直接积分法计算该种结构的动力响应时，应该考虑采用不引起振幅率减小的Newmark-β法，以保证高阶模态响应的贡献仍然保留在响应中而不致于被忽略。

针对临床中大量的继发性膝关节OA病例，孟和教授强调了生物力学在病因学、病理学及治疗学中的重要地位：&尽管有酶类及免疫反应的参予降低了关节软骨的屈服强度，但要磨损到骨质外露却离不开应力的作用&。

The simulation results show that calculated tortuosities varies with network connectivity as well as the Thiele modulus.This work also suggests that tortuosities obtained under diffusion-only conditions can only be used under the strong reaction control conditions.

模拟结果表明，计算出的曲折因子既是孔网络配位数的函数，又随Thiele模数的变化而不同，在纯扩散条件下测得的有效扩散系数只能应用于扩散影响不严重的反应扩散区域。

作为半主动控制系统的经典范例之一，变阻尼控制系统已经在结构控制领域得到了广泛的应用，但是近来的研究显示变阻尼控制对于抑制柔性结构的地震反应是适宜的，而对于刚性结构则是不适宜的。

However, due to the structure of alkali metal atoms in different electronic transition energy when the change is not the same as on the different wavelengths of light, the color reaction from the flame in the experiment see the special flame color, the color spectrum is the spectrum.

但由于碱金属的原子结构不同，电子跃迁时能量的变化就不相同，就发出不同波长的光，，从焰色反应的实验里所看到的特殊焰色，就是光谱谱线的颜色。

The results show that glycerol, as surfactant, with a concentration of I % can alternate the interfacial tension between water and oil to some extent; thusly, the conglomeration problem can be inhibited during the microencapsulation process. Meanwhile, by controlling the reaction rate of condensation polymerization and adjusting the pH of the system, the floccules can be restrained effectively, and microcapsules with smooth surfaces are obtained. Finally, the addition of NH4Cl may result in properly strengthened microcapsules to resist the collapse during nature drying.

结果表明：采用质量分数为1%甘油做表面活性剂，可适当调节油／水界面张力，抑制微胶囊化过程中的黏结团聚；通过调节体系pH值，控制缩聚反应速率，可有效抑制水相中絮状树脂的产生，得到表面光滑的微胶囊；采用氯化铵作固化剂对微胶囊进行固化，可有效提高微胶囊的机械强度，得到在自然干燥后不破裂的微胶囊。
