提出了一种推导两相流中长界面波演化方程的通用方法。特别注意曲线坐标中应力条件的形式。该方法适用于界面无应力的一类薄膜流。给出了平面和圆柱形膜流的所得演化方程，并讨论和展示了这些方程的简单“守恒”形式。
A general method-for deriving evolution equations for long interfacial waves in two-phase flow is presented. Particular attention is paid to the form of the stress conditions in curvilinear coordinates. The method is applied to a class of film flows in which the interface is stress-free. The resulting evolution equations are presented for both planar and cylindrical film flows and the simple “conservation“ form of these equations is discussed and exhibited.
