摘　　要：研究带一阶强迫项的脉冲时滞微分方程的振动性,借助于Kartsatos变换,得到了若干判别这类方程振动的充分性条件,所得的结果推广并改进了时滞微分方程振动性理论中某些已知的相关结果。The purpose of this paper is to investigate the oscillations of first order impulses delay differential equations with forcing term. By using the Kartsatos＇s transformation, we obtain some sufficient conditions of oscillation for them. The results improve and generalize some known results of the oscillation theory of delay differential equations.
