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。

Given the strong guiding significance of Efficient Market Hypothesis for academic research and actual investment, this thesis will make an objective evaluation for the efficiency of Chinas stock market from the view of demonstrational test.

Under the guidance of the theories of sedimentation, paleontology, stratigraphy, reservoir geology and digenesis, synthetically applying the methods of the conjunction of spot-line-surface, macro-microscopic and field-indoor, there is a comprehensive study for the upper Permian series in stratum, rock, sedimentary facies and diagenesis, especial for the type and characteristics of sedimentary facies, in the paper.

本文主要是以沉积学、古生物学、地层学、储层地质学等相关理论为指导，运用点线面、野外与室内、宏观与微观相结合的方法，并借助普通显微镜、阴极发光显微镜等手段对川西地区北部上二叠统的地层、岩石、沉积相以及成岩作用进行了研究，尤其是对沉积相的类型及特征作了详细的划分与阐述。

At the same time, according to the CMM operational principle and the direction cosine of geometric elements, a thought of using direction cosine to analyze the oversize geometric tolerance reasons was proposed and its relevant example was shown, which can expand the way of quality analyses and guide to produce eligible machine parts.
