摘　　要：关于一阶线性时滞微分方程的解的性质已有许多讨论 ,特别是解的振动性研究已获得一些充分条件 ,本文给出了关于一阶线性时滞微分方程的解的振动性的几类新条件 ,并包含了有关已有结果 .There were many discussions on the properties of solutions for the first order linear delay differ- ential equation. In particular,some sufficient conditions were given for the oscillations of solutions. This paper presented certain new conditions for the oscillations of solutions of the firstorder linear delay differ- ential equations.
