文献[1-7]对某些特殊情况研究了气体夹带液体层的线性稳定性问题。在文献[8]中，线性问题用数值方法求解，并与某些特殊情况下的解析解作了比较。在本论文中，线性分析的结果更全面地介绍;有限振幅的稳定性的膜的问题提出和数值解决;线性和非线性分析的结果进行了比较与作者和其他实验人员进行的实验数据。
The problem of the linear stability of a layer of liquid entrained by a gas has been investigated for some special cases in [1–7]. In [8], the linear problem was solved numerically and the solution compared with some analytic solutions for special cases of the flow. In the present paper, the results of linear analysis are presented more comprehensively; the problem of finite-amplitude stability of the film is posed and solved numerically; the results of the linear and nonlinear analysis are compared with data of an experiment performed by the authors and by other experimentalists.
