尽管涡振是一种限幅振动，但由于其发生风速较低，振幅相对较大，会影响结构的强度和疲劳，因此大跨度拱桥的涡振响应研究具有重要的意义。
Vortex-induced vibration is limited amplitude response, but it occurs at low wind speed with relative large amplitude, which will affect the strength and fatigue resistance of the structure.
本文用FE3C 8500程序计算了渗碳体的结构振幅，据此，说明了渗碳体的结构消光条件。
The structure amplitudes of Fe_3C are calculated by using the program FE3C8500, then the condition of structure extinction is introduced in this paper.
我有时听到有人说“嗯，让我们加大动画振幅，看看在屏幕上我们能否破坏结构”。 （当然，这也太荒谬了！！！
Sometimes I've been known to say "well let's increase the amplitude of the animation and see if we get the structure to break on the screen". (Of course, this is ridiculous! ! !
