通过实例计算，定量地分析了结构内部损伤度、损伤位置和损伤区域大小对接收波幅值和波到达时间的影响。
By the examples computation, the effects of the damage degree, damage location and zone on the amplitude and the arrival time of the received wave were quantitatively analyzed.
通常，波长较短传播较慢—但是破坏性要大的多—的S波会随之而来。 通过这两种波到达时间的差值可以估算震中的距离。
type of waves can be used to estimate distance to the epicenter.
因此，实际观测得到的反射波到达时间，并不是标准的双曲线，而是一条畸变了的双曲线，从而影响速度分析和迭加效果的质量。
Therefore, the actual observation obtains the reflection time, is not the standard hyperbolic curve, but was a distortion hyperbolic curve, thus influence speed analysis and iteration effect quality.
当脉冲作用点在受损单元的起始位置时，脉冲作用点横向速度波首波波幅变化越大，损伤越大，脉冲作用点横向速度波的第一个波谷到达时间越晚，损伤单元越长。
The greater the amplitude change of head wave of transverse velocity is, the severer the damage is, the later the arriving time of the first wave hollow and the longer the damaged element will be.
格伦：克里斯托弗，请你抓紧时间，不然我们就不能准时到达冰球场了。快点啊。我们半路上还要接大山和云波呢。
Glen: Christopher, please hurry up or we won't get to the arena on time. Come on. We have to pick up Dashan and Yunbo on the way.
声学精度靶就是利用伴随着超声速弹丸的弹头波到达立靶面上不同声学传感器所产生的时间差来确定弹丸在面上的坐标。
Acoustic precision target utilizes the time difference of warhead wave arrived at different sensors to determine coordinates of bullet on the surface.
