摘　　要：考虑了一类带强迫项的脉冲时滞抛物方程组,利用脉冲时滞微分不等式,获得了该类方程组的解强迫振动的若干充分判据.In this present paper, we study a class of nonlinear impulsive delay partial differential parabolic equations. Some sufficient conditions for the forced oscillation of solutions of such equations are obtained by using impulsive delay differential inequalities.
