摘　　要：利用压缩映射原理,研究一类非线性多时滞的脉冲微分方程的概周期解,获得了方程的概周期解存在的充分条件.With respect to the almost periodic solutions to a nonlinear impulsive differential equations with delay,a study is made on their existence by means of the fixed point theorem.Sufficient conditions are given to the almost periodic solutions of these equations for ensuring their existence under some assumptions.

关 键 词：脉冲时滞微分方程 压缩映射原理 概周期解
