研究了界面粘度在二维垂直下落液膜中的作用。自由界面位移的非线性演化方程具有经典形式（即，组合Korteweg-de弗里斯和Kuramoto-Sivashinsky方程），界面粘度支持色散项的存在，该色散项的物理作用以前已经在文献中示出，以类似孤子的图案的形式影响界面扰动的排序。
The role of interfacial viscosities in a two‐dimensional vertically falling liquid film is examined. A nonlinear evolution equation for the free interface displacement from planar shape is found to possess classical form (i.e., combining the Korteweg–de Vries and Kuramoto–Sivashinsky equations), with interfacial viscosities supporting the existence of a dispersive term whose physical role has formerly been shown in the literature to effect an ordering of interfacial disturbances in the form of solitonlike patterns.
