A study of regional geological setting and ore-control factors for the Xiasai Ag-Pb-Zn deposit indicates that NW-trending structures act as conduits for ore fluids and orebodies are controlled by a NNw-trending fault system, while ore shoot s are confined equidistantly to secondary structures associated with the NNW-trending fault system.

研究结果表明，富矿体在NNW向断裂中按一定间距连续出现，并在NNW向断裂伴生的次级构造中集中产出。

Considering no construction analysis oriented software for long-span space structures exists in the domestic engineering software market in China, a constructionmodule is developed upon the platform of MSTCAD, a famous domestic software for space grid structures design. This will not only enhance the software functions, but also meets the growing domestic demand for construction analysis software.

最后，针对目前国内大跨度空间结构施工分析软件缺乏的现状，在MSTCAD软件平台上增加施工功能的吊装模块，在模块中实现吊装的目标函数满意度选择起吊高度功能和最小应变能法选择吊点布局的功能，并且通过各类吊装参数的预输入给予用户方便快捷的选择，使得MSTCAD软件逐步完善成为国内领先的设计及施工分析软件。

Based on the modified Hertz contact theory and the simplified simulation of impact a new method is approved to calculate the impact force of outrunner blocks in debris flow on structures. Based on a limited parametric study, it is shown that the impact causes plastic deformation on concrete structures at a low velocity.

计算结果表明，泥石流大块石在很小的冲击速度（小于1m/s）下就可能导致混凝土材料冲击接触面上产生塑性变形。

With the development of social economy and engineering technology, a lot of overlong concrete structures have been constructed throughout the country. An important study on these structures is how to deal with structural cracks aroused by temperature variation and concrete shrinkage.

随着经济的发展和工程技术的进步，全国各地涌现出了一大批超长混凝土结构，对这些结构的研究重点之一就是如何处理温度作用和混凝土收缩引起的结构开裂。

Proximal structures to the overthrust belt evidence compressional folding and faulting indicative ofahorizontal maximum principal stress, but the dominant principal stress of the more distal and productive structures is vertical.

近端结构的推覆带的证据和断层挤压折叠指示ofahorizontal最大主应力，但占主导地位的主应力较远端和生产结构的垂直。

The structures always co-exists with the palimpsest ripples, the wrinkle structures, and so on.

这种沉积构造常与变余波痕、皱饰构造等相伴产出。

In this paper, in cognizance of the lack of accuracy of the calculation results in the current method of seismic analysis for the frame structures, the paper is searching for a new approach, using continuous models and through the establishment of the partial differential equations to carry on the dynamic analysis of the fiame structures, the limited units will be expanded to the unlimited units, each component as a continuous unit to deal with without the need of further subdivision, making the structure of dynamic behavior closer to the actual behavior and to improve the accuracy of the results.

本文针对当前框架结构抗震分析的动力时程法计算结果不精确的不足，寻求一种采用连续模型并通过建立偏微分方程来对框架结构进行动力分析的新方法，把每个构件作为一个连续单元来处理而不需要再细分，使得结构的动力行为与实际更为接近，从而提高计算结果的精度。
