摘　　要：本文研究一类具高阶Laplace算子的非线性脉冲中立型时滞抛物偏微分方程的振动性质,利用一阶脉冲时滞微分不等式,获得了该类方程在两类不同边值条件下所有解振动的若干充分性判据。所得结论将脉冲时滞微分方程的振动性质推广到脉冲中立型时滞偏微分方程,同时也反映了脉冲和时滞在振动中的影响作用。This paper studied the oscillatory properties of a class of nonlinear impulsive neutral delay parabolic partial differential equations with higher order Laplace operator. By using first order impulsive delay differential inequalities, some sufficient criteria for the oscillation of all solutions of such equations are obtained under two kinds of boundary value conditions. These results extend the oscillatory properties of impulsive delay differential equations to impulsive neutral delay partial differential equations and also reflect the influence action of impulsive and delay in oscillation.
