摘　　要：利用渐近概周期微分方程的渐近概周期解,讨论了一类逐段常变量线性微分方程的概周期解的存在性.利用不动点理论给出了这类方程对应的非线性微分方程的渐近概周期解存在的条件.The existence of almost periodic solutions for a class of linear differential equations with piece wise constant argument is examined by asymptotically almost peridic solutions of asymptotically almost periodic diferential equations, giving the existence conditions the existence conditions concerned.
