Defect and Improvement of Two-Time Expansion Method in Nonlinear Oscillations

摘要: 本文指出了非线性振动中两变量型尺度法存在的问题并进行了改进.最后证明了改进的两变量型尺度法与КВМ法等价.

Abstract: In this paper,the defect of the Two-Time Expansion method is indicated and an improvement of this method is suggested.Certain examples.in which the present method is used,are given.Moreover,the paper shows the equivalence of the improved Two-Time Expansion Method and the method of КВМ(Крылов-Воголюбов-Мигроцолъский)
