摘要：

The nonlinear system of approximate equations is obtained for thin annular films flowing down vertical fibers. The multiparameter perturbation approach is used which justifies the theory for a much wider range of basic flow parameters than the more conventional methods. From the evolution equation that is applicable to the strongly undulating films which are perpetually on the verge of break up, certain dependences follow from observable quantities, in excellent agreement with experiments.
