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。
Previous studies show that both dynamite borehole shots and vertical vibrations from controllable seismic sources at the surface will produce relatively strong pure P-waves and weaker pure S-waves.
已有的研究表明，炸药震源在井下激发、可控震源在地面垂向振动，均会产生较强的纯纵波和一定强度的纯横波；泊松比差别较大的分界面有利于形成较强的透射转换横波。
