The rectangle shaped member mentioned by this article is a prefabricated one for the internal construction of circular tunnel, and is located along tunnel axis line, to be lifted into place by a dedicated crane onboard the shield machine in synchronised manner, followed by placement at both sides of tunnel, of ballast block, or in-situ cast members, corbel, pavement slab and the like.

由于隧道比较长，为节约工期，在盾构机推进的同时，隧道的内部结构也跟进施工，本文所叙述的口字型构件是圆隧道内部结构中的预制构件，它位于圆隧道的中心轴线位置，在同步施工中由盾构机上的专门起重机吊放入位，再于两侧施工压重块、牛腿、路面板等现浇结构。

The energy dissipated is given in terms of the specific damping capacity of the structure, which gives a measurement of energy dissipation. A scheme based on the correspondence principle to obtain an estimation of the specific damping capacity was derived. It makes use of an intrinsic equation of the dynamic system, and about the cor...

On one hand, globalization courses the change of space economic structure and the restructure of world urban systems. The space economic structure changes from industry chain to a value chain structure. On the other hand, more and more progress of regions and countries has been brought into the global economic network. The rivalry between these countries often present between regions and cities. The global competitive advantage of cosmopolis and the surrounding town compact districts is a critical component of the countrys integrate competitive advantage.

一方面，全球化导致空间经济结构的转型和世界城市体系的重组，以"产业链"为特征的空间经济结构正在转变成为以"价值链"为特征的空间经济结构；另一方面，各国的城市和区域的发展越来越纳入全球经济网络，经济全球化背景下的国家竞争已经更多地表现为城市和区域之间的竞争，以国际大都市为核心的城镇密集区域的国际竞争力是国家综合竞争力的重要组成部分。

A four\|node piezoelectric composite laminated plated element was implemented for dynamic analysis of adaptive structure. The damping ratios of truncated models were considered as the control objects, so that each of the structural modal oscillation could decay rapidly. Hence, the structural oscillation was effectively controlled.

From this experiment, frequency response function could be found, and modal parameter also could be known by curve fitting, then compared with the differences of mode shape and natural frequency by using those modal parameters, also compared with finite element analysis, the results could be applied to detect the structure of beams and prevent it from damage and corrode for the safety in the future.

将实验中三种驱动器搭配加速度计实验分析结果较佳的一组方法，来从事结构之非破坏检测，探讨当固定梁有缺陷产生时，其结构之自然频率与模态振型的变化，并比较其不同缺陷处之固定梁实验模态结果，将来可应用於梁结构物损坏或腐蚀时侦测其安全性之分析。

So the Reverse Construction Method is the designing of execution and construction, these two facts must be combined very closely. Diaphragm wall have three effects in the Reverse Construction Method, it can countercheck soil, compose the construction and countercheck water.

地下连续墙和立柱，既是施工过程中的临时支护体系，同时又要作为地下结构的永久结构体系，因此逆作法设计不仅是施工设计同时也是结构设计，两者必须紧密结合。

At last, according to system theory of corporate governance studied, this paper analyzes governance system of Chinese state-owned and its effective factors, and advances complete countermove idea of corporate governance system.

最后，根据研究出的公司治理结构系统理论，分析了中国国有企业治理结构系统及其影响因素，并提出了完善公司治理结构的对策思路。

Since it is very difficult to established the model via ANSYS software, UG software is used to set up the model. In the fourth chapter, the bus body"sstructure are analyzed by ANSYS software. Three work situations of bus body are discussed, which are bend work situation, torsion work situation and crankle work situation. The stiffness and strength of bus body"s structure are calculated to guide the design of bus bodys structure.

由于使用ANSYS软件建模很不方便，本文使用UG软件建模，利用UG软件的图形数据转换接口，将作好的模型导入ANSYS中处理；第四章主要是介绍了如何使用ANSYS软件进行客车车身结构的分析，文中讨论了客车的三种使用工况，弯曲工况、扭转工况和弯扭工况，计算了客车车身的结构强度和刚度用于指导客车车身结构的设计。

Complexes have been determined by single crystal X-ray diffraction, and study the influence factor of their structure through the discussion of crystal structure of these compounds.
