And if you scatter you can have an elastic scattering crosssection or an inelastic scattering cross section which are combined to the fundamental scattering cross section.
如果你们有一个弹性散射，横截面或非弹性散射横截面，那是结合成基本的散射，横截面。

There are many long and elastic round cross-section rod structures in quayside container crane, whose frequency are so low that it is easy to arouse crosswind resonance.
岸边起重机结构中有许多长的弹性圆截面杆件，自振频率比较低，很容易发生横风共振。

Critical force and deformation of elastic restraint rod not only depend on the rod crosssection, but also on the restraint condition.
