摘　　要：将摄动方法应用于海洋平台非比例阻尼系统,使非比例阻尼问题转化为一系列比例阻尼问题的迭加.然后,又对方法的收敛性进行了研究,并给出了收敛条件.最后,通过算例证明了文中方法的正确性与有效性.The perturbation method is applied to non-proportional damping system, by which the non - proportional damping problem is transformed into a series of proportional damping ones in the superposition form. The convergence of the proposed method is approached and the convergence conditions are given. The examples show that the proposed method is proper'and effective.
