将这一结果应用于P-SV转换波的速度分析和叠加处理中。

The result is applied to analysis of velocity and stacking of the P-SV converted-wave.

在1995年，人们首次提出，长号能产生一种高能压力波，它的速度能略超音速。

It was first suggested in 1995 that the intense pressure waves, which can briefly exceed the speed of sound, could come from trombones.

速度升高到1.3马赫（速度单位，1马赫=音速=340.29m/s——译者注）以后，不会再对冲击波强度造成太大的影响。

Increasing speeds above Mach 1.3 results in only small changes in shock wave strength.

Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.

好了，我们已经定义了，这些术语，我们知道了，频率和波长，现在可以来考虑,波的速度了，特别是光波的速度，速度等于它走过的距离,除以所用的时间，因为我们。
