In this paper, for the first time, floor stiffness is denoted as shear stiffness, which reflects the influence of floor length to width ratio more effective than floor bend-shear stiffness.
本文首次把楼板的刚度用剪切刚度表示，它比楼板的弯剪刚度更能体现楼板长宽比对楼板刚性的影响。

By means of the pressure loss in three kinds of bend configuration. it is found out that the short radius elbows appear to yield the lowest pressure loss in a wide range of mass over air ratio.
通过三类弯管形式压损试验，发现了短半径弯头在一个较大料气输送比范围内均产生最小压损；
