英文: 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 measurement transverse wave produced by grazing incidence longitudinal wave.
中文: 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。
