| 摘 要： | 在文献7]的基础上，通过合理地降低竖壁液膜流流动方程的维数，采用奇异性理论，分析了液膜流的流态演化过程及其与瑞利数的关系，指出在特定瑞利数下，竖壁液膜流由光滑的层流演化为驻波状的波状流，又演化为行波状流，最终进入混沌的演化过程，从而对竖壁液膜流的流态演化机理作出深化的探讨及合理的解释．

| Abstract: | Following our previous suggestion7], the relationship between flow mode evolution and Rayleigh number was theoretically investigated. An analysis was conducted by using the singular theory to account rationally the evolving process of a thin falling liquid film along a heated vertical surface. |
