It is assumed that the reader has previously studied the analysis of certain types of trusses in a course of statics . 假定读者在静力学课程中已经学过某些类型桁架的分析。
Conventional earthquake-resistent design involves engineering that a structure under design can carry a set of static lateral . 传统的抗震设计要求所设计的结构物能承受一组侧向静载荷。
By 1960 foreign aid policy had been static for nearly a decade, in its conceptions as well as its programs . 到1960年,对外援助政策不论是在概念上还是行动计划上,都一直停滞了近十年之久。
Typically, this principle employs the geometrical relations between various displacements in order to solve problems of statics . 为了解静力学问题,这个原理典型地使用了各种位移回的几何关系。
The static behavior of the new design was shown to be completely satisfactory by subsequent tests on a model thus modified . 以后进行的这样修改后的模型试验表明,新设计结构的静力性能是很好的。
Also, the difference in pressure between any two points in a bed is roughly approximated by the static head of bed between these points . 还有,床层中任意两点间的压差大致等于这两点间床层静压头。
Usually the rake body makes the static readings high, and by shortening the tipstatic-orifice distance the error can be eliminated . 一般排管架使静压读数偏高,缩小管端静压孔的距离可以消除这个误差。
Static evaluation is used to determine motions in a direction that bisects the angle between the directions of illumination and observation . 静力学计算是用来决定照射方向与观察方向之间的角分线方向的运动。
The assumption is made that the changes in aerodynamic loading take place so slowly that the structure is at all times in static equilibrium . 假定气动载荷的变化相当慢以至于在所有时刻结构都处于静平衡状态。
We now focus attention on electron 1 and regarded electrons 2, 3…n, as being smeared out to form a static distribution of electric charge . 我们现在把注意力集中在电子1,而把电子2,3…,n看成是弥散开形成一个稳定的电荷分布。
