摘　　要：讨论了带强迫项的次线性时滞微分系统在非线性脉冲扰动下系统解的渐近性,得到了带强迫项的次线性时滞微分系统在非线性脉冲扰动下系统解渐近吸引的充分性条件.The paper mainly discusses the asymptotic property of solution for forced sub-linear variable delay differential system under nonlinear impulsive perturbations. Sufficient conditions for asymptotic property of all solutions to forced sub-linear delay differential system under nonlinear impulsive perturbations are obtained.
