利用新的处理非线性扩散项的技巧及脉冲时滞微分不等式，研究一类具脉冲效应和非线性扩散项的时滞抛物系统在第一类边界条件下的振动性，得到了该类系统所有解振动的若干新的充分性条件。结果表明，系统振动是由脉冲和时滞效应引起的。

Using a new technique of treating nonlinear diffusion term and impulsive delay differential inequalities,the authors studied the oscillation problems for a class of delay parabolic systems with impulse effect and nonlinear diffusion term under first boundary condition and some new sufficient conditions are established for the oscillation of all solutions of such systems.The results obtained fully indicate that the system oscillation is caused by the effect of impulse and delay.
