摘要
用改进的ＬＰ方法将强非线性系统变换成一个具有小参数的系统，用多尺度法求出了变换以后的系统的频响函数。
A strongly nonlinear system with large
parameter is transformed into a small parameter system by using the modified LP method.The
frequency-response function of the new system is determined by the multiple scales method. A
method for determing the approximate frequency-response function of strongly nonlinear system
is presented. 4refs.
