依据所建立的非线性模型，获得垂直入射纵波在非线性法向变形节理处传播的透射和反射系数的解析解。

Based on the established model, the analytic resolution of transmitted and reflected coefficients is obtained when the normal incident P-wave propagates to the nonlinear normal deformative joint.

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。

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.
