Hydrodynamic instabilities in thin (0(.01-10 um)) fluid films caused by interfacial effects are theoretically studied. Three different types of interfacial instabilities are under investigation: a Marangoni instability resulting from a transverse temperature gradient across the film; instabilities arising from capillary action at the free interface of an annular film; and surface chemical reaction induced instabilities. In each of these investigations, the film is modeled as a viscoelastic liquid, and particular attention is focused on the nonlinear stability characteristics, and the deformation patterns of the film which may arise in nonlinear asymptotic states.

薄（0（.01-10 μ m））流体膜中的流体动力学不稳定性 从理论上研究了界面效应。 三种不同类型 的界面不稳定性正在调查：一个Marangoni 横向温度梯度引起的不稳定性 膜;自由界面处毛细作用引起的不稳定性 环形膜;和表面化学反应诱导 不稳定性 在每一个调查中，电影都被建模为 粘弹性液体，特别注意的是集中在 非线性稳定特性，以及变形模式， 膜可能出现在非线性渐近状态。
