| 摘 要： | 本文在奇异摄动理论中的KBM方法的基础上,利用振幅a的幂级数展开,求解了有较大阻尼(阻尼系数为0(1)量级)的非线性振动问题(包抱自治系统与非自治系统),改进了KBM方法,作为例子,利用改进的KBM方法求解高次非线性振动.

| Abstract: | In terms of thr KBM method in the singular pertur-bations, this paper considered autonomous and ponautonomus nonlinearoscillating problems with larger damping(the damping coefficient is ofO(i)) by expansion in power series of amplitude a and improved the KBMmethod. As an example high--order nonlinear oscillation is worked outby the modified KBM method. |
