摘　　要：本文利用指数二分及差分方程的渐近概周期序列解,讨论了一类具有变系数逐段常变量微分方程组的渐近概周期解的存在及唯一性.In this paper, we discuss the unique existence of asymptotically almost periodic solution for the systems of varying coefficient differential equations with piecewise constant argument by virtue of the exponential dichotomy and asymptotically almost periodic sequence solution of difference equations.

关 键 词：逐段常变量 渐近概周期解 指数二分
