摘　　要：用插值摄动法和线化摄动法相结合的方法求解了一类保守系统的强非线性振动问题,有较好的精度,并 优于改进的L-P法.In this paper, using the linearization and the interpolation methods, the author seeks to solve a class of problems of the strongly nonlinear oscillations of the conservative systems. The accuracy of this method is quite well and is better than that of the improved L-P method.
