Random transform has been widely used in seismic exploration, for example, suppression of multiple, separation of P- and S-waves, seismic migration and inversion etc.

拉冬变换在地震勘探领域有广泛的应用，如压制多次波、纵横波分离、地震偏移及反演等。

Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or initial rupture point.

由于 P 波和 S 波以不同但相当恒定的速度传播，它们到达的间隔与到震源或初始破裂点的距离成比例地增加。

Using MTS Ultrasonic Measurement System, we studied the influences of water of saturation and pore pressure on velocities of compressional (P) and shear (S) waves in exposure rock specimens.

我们用MTS的超声波测试系统研究了地表岩样饱和水及孔隙压力对纵横波速度的影响。

So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.

例如这是平均位置，在峰的位置水位高，在谷水位低，我们也可以,讨论声波它也是某种,量的周期变化，在这里我们,讨论的是密度,我们有高密度区和低密度区。
