摘 要: 讨论了二阶脉冲时滞微分方程解的渐近性态,得到了其有界非振动解的趋零性与无界非振动解的趋于无穷大性,所得结果推广和改善了现有的结果,体现了脉冲效应对方程解的关键性影响. In this paper,we consider the asymptotic behavior of the second order impulsive delay differential equations . Some sufficient conditions about the asymptotic behavior of nonlinear differential equations are obtained. Extended and improved the known results. The importance of the impulsive effect on the equations is stressed.
