水轮机；蜗壳；座环；水泥基础；优化设计

An optimum design for the complex body formed together with the volute casing, base ring and cement foundation of a hydraulic turbine is made by the gradient method and a program is developed on the basis of finite element analysis with the plane and shell element, body element, boundary element and pseudo element.

本文对由水轮机蜗壳、座环和水泥基础所构成的复杂组合体，在采用板壳元、块体元、边界元和伪单元等四类单元进行有限元分析的基础上，选用最速下降法研究了优化设计过程，并编制成程序系统。

滚球 本展品综合采用了多种机械机构和传动原理，有杠杆、连杆、滑轮、凸轮、带传动、链传动、螺旋传动、齿轮传动、蜗杆传动等，协同完成滚球的输送任务。

The elastic contact between steel liner and surrounding concrete as well as the softening of concrete and damage under tension were considered. The analysis results of concrete damage in different parts surrounding the spiral case and vertical displacement of turbine and generator foundations were obtained. In addition, based on the damage analysis of concrete the flexibility check for stay ring was also carried out.

数值计算模型考虑了钢衬和外围混凝土之间的摩擦接触、混凝土材料的拉伸软化和损伤特性，对外围混凝土的损伤指标及分布、各钢部件应力、结构位移等进行了分析研究，并在蜗壳外围混凝土发生损伤的情况下对座环柔度进行了复核。

Because of the asymmetry of the inlet structure and the unstable characteristics of the swirl flow,the spinning center of the gas flow deviated from the geometrical center of the cyclone,which resulted in the asymmetry of the flow field and the change of the three dimensional velocity components.

蜗壳式旋风分离器入口结构的非轴对称以及气相旋流的不稳定性造成了气流的旋转中心与旋风分离器的几何中心不重合，从而导致了气相流场三维速度的非轴对称分布以及速度分量由于基准不同而产生的大小和方向变化。

Precision dividing and spiral word with greater precision and efficiency than ever The dividing head can be tiled from a horiaontal position of 90down to -10 from vertacil,and inclinations can be read off a scale graduated in degrees.

通过蜗轮分度装置（传动比为1：4），适用于高标准的检测及测试，可以与铣床、磨床、钻床以及其他机床配套使用，完成各种角度工件的分度加工。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
