研究一类非线性脉冲中立型时滞抛物偏微分方程解的振动性，借助一阶脉冲中立型微分不等式，获得了该类方程在两类不同边值条件下振动的若干新的充分性判据．所得结果改进了已有的结果，且充分反映了脉冲和时滞在振动中的影响作用．

The present paper deals with oscillatory properties of solutions for a class of nonlinear impulsive neutral delay parabolic partial differential equations and some new sufficient criteria for oscillation of the equations are obtained under Robin and Dirichlet boundary value conditions via impulsive neutral differential inequalities of first order. The results of this paper improve some known ones and fully reflect the...
