1·The relations between the longitudinal and transversal waves, the wave velocities of rock mass and rock were also described in it.

文章还统计了纵波和横波、岩体波速和岩石波速的关系，可供选用指标时参考。

2·The character and structure of instability of transversal wave disturbance is studied in this paper by using calculating the spectrum and spectral function of the transversal wave disturbance.

采用计算横波型扰动波谱和谱函数的方法，研究了当基本气流具有垂直线性切变、层结参数为常值时横波型扰动的不稳定，给出了不稳定扰动的结构，讨论了不稳定的性质。

3·The conversion region, which transfers the energy of the transversal motion into longitudinal motion, is an important part of a cyclotron wave converter.

能量转换区是回旋波整流器的一个重要组成部分，它把电子的横向能量转化为纵向能量。
