摘　　要：本文将摄动方法应用于薄板的塑性动力响应问题中。文中应用摄动方法分析了阻尼介质对圆板塑性动力响应的影响 ,得到了这一问题的一致有效的解的展开式。同时讨论了圆板停止运动的时间τf与阻尼系数ε之间的关系。This paper applies perturbance method to the problem of plastic d yna mic response of thin plate.By means of perturbance method,the author analyses th e influence which damping medium has on plastic dynamic response of circular pla te in the paper and gets the consistent,effective expanded form of the solution to this problem.At the same time.the author discuc the relationship between time ,τ f,which circular plate stops moving,and damping coefficient sses ε.
