阐述了摄动方法中的多变量展开法 ,并利用此法讨论了拟线性系统振动问题的近似解 ,计算结果表明 :它具有数值计算简单、形式合理。

This paper describes a kind of multi-variable expansion of perturbation method. By applying the method, the paper makes a discussion on the approximate solutio n to the problem of quasi-linear vibration. The calculating result shows its ad vantage of the simpleness in numerical calculating, the exact form and the broad ness in application.
