Two methods of determining the yield base shear and the yield top displacement of RC frames are suggested.

提出了两种确定钢筋混凝土框架的屈服基底剪力和屈服顶点位移方法。

The second order effects enlarge the requirement of top displacement and story drift and diminish that of base shear.

二阶效应增大了结构的顶点位移最大值和层间位移角最大值，减小了结构的基底剪力最大值。

The calculation of top displacement of telescopic hydraulic cylinder and the evaluation of structural rigidity are emphasized.

着重讨论了伸缩液压缸顶端位移的计算以及对结构刚度的评定方法。

youdao

So now that means if this is where the center of positive excess charge lies and on top of it is the center there is no displacement of the charge so there is no net dipole.

所以现在我们说,如果正电荷中心,就位于,那么还是在这里负电荷中心也在这里,所以没有空间偶极。
