结果表明，对非均匀层进行分层后，结构在低频时的吸声性能有所提高。

When the non-homogenous layer is divided, the sound absorption performance of the structures is increased in low frequency.

本文应用WKB方法研究了在弱非均匀层结大气中，当基本气流具有弱垂直切变时，重力惯性内波的稳定性问题。

This paper discusses the stability of internal inertial gravity wave in the heterogeneous stratified atmosphere when basic flow appears to be weak vertical shear by the WKB method.

如果颗粒在液滴表面形成一层均匀的膜，且基本延伸到液滴的两极，那么合并会形成一个非球形的结构；

If the particles covered both drops with a uniform film, extending almost to the poles, the coalescence resulted in a non-spherical structure.
