The purpose of briefly introduction of the establishment course and the theory of solution of the dynamic finite element equation of the bridge is based our following analysis and comparison on.

本文的主要工作有：(1)简单介绍下桥梁动力有限元方程的建立过程和求解理论，为后续的分析比较作一定的理论铺垫。

The development mechanisms of backflow precipitation are analyzed with the reasonable simulation results. The results show that dynamical frontogenesis plays a very important role in the development of backflow snowstorm. The frontogenetical secondary circulation directly causes the snowstorm.

在回流暴雪形成与发展的过程中，动力锋生机制发挥了重要作用；其产生的锋面次级环流是造成这次暴雪的主要原因；降水过程中，雨雪相态的转变与温度廊线有直接关系，随着降水由雨转为雪，雪水混合比增大迅速且其高度有所降低。

It was fueled and funded by housing, and housing was its primary product.

繁荣的动力和融资来自于房屋，房屋是其主要产品。

The results show that wind divergence that is corresponding to the rain area forms at the windward side. After horizontal flow gets over the windward side, vertical circulation flow of climbing-ascending-descending form above the mountaintop. The ice crystal locates in the upper level, and below it there is snow and graupel, the cloud water and rain water is in the low level of the cloud.

此次暴雨过程的动力场、云和降水微物理过程的主要特征是：水平气流在迎风坡附近形成风场辐合，雨区与辐合区位置基本一致，垂直方向上出现明显的气流爬升—上升—下沉的中尺度环流。

A few years later he took over as editor-in-chief from Gros, who was needed in other operations of the growing enterprise, and has been the driving force of Casino Player and Strictly Slots ever since.

几年后，他接任总编辑的企业主要来自格罗斯，谁是成长所需要的其他业务，并已和严格的动力，赌场的玩家，角子机至今。

The growing acceptance of distributed/remote I/O as a means of reducing costs associated with hardwiring devices to local I/O at controllers provides the major impetus for growth.

被分配/遥远的输入／输出如减少与费用有关的在控制器的对当地的输入／输出的 hardwiring 装置的方法的的增加接受度提供主要的动力给生长。

The main content consists of three parts:(1) analyzing the structural dynamic changing rule considering SSI effect;(2) analyzing the earthquake response of traditional non-shake -isolate frameworks before or after considering SSI effect, and then summarizing the rules that how factors such as base-soil elastic modulus and damping ratio effect structural horizontal deflection, displacement between floors and girder-end moment;(3) analyzing the earthquake response of shake-isolate frameworks considering SSI effect or not, indicating the changes after considering SSI effect and the performance of rubber shake-isolate pad.

本文采用通用有限元程序ANSYS，对在7度多遇地震时El Centro波作用下框架的地震响应进行了分析，主要内容分为三部分：（1）分析了考虑SSI效应后结构的动力特性变化规律；（2）对传统非隔震框架结构考虑SSI效应前后的地震响应进行了分析，总结出地基土弹性模量、体系阻尼比等因素对结构各层水平位移、层间位移以及梁端弯矩的影响规律；（3）对考虑与不考虑SSI效应的基础隔震结构的地震响应进行了分析，指出了考虑SSI效应后基础隔震结构地震响应的变化规律和隔震效果。

The hovercraft proved to be a failure mainly because of its power system.

气垫车失败的主要原因在于其动力系统。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
