本文首次探讨了对弹性波在传播过程中的反射和波型转换有任制作用的弹性波方程的形式。

Several approximate elastic wave equations in which reflection and conversionare weaker than in accurate ones are first discussed in the paper.

以复合绝缘子为测量样品，为提高测量横波的精度，根据超声波在边界上的波型转换条件，使用常规纵波探头对由掠入射纵波产生的横波进行测量。

Taking the composite insulator as a measurement sample, knowing the waveform conversion condition on the boundary, only a conventional longitudinal testing probe is needed to measure...
