摘　　要：借助内积降维方法,利用Riccati变换,引入参数函数,将一类具有阻尼项和连续分布滞量的二阶向量中立型偏微分方程的H-振动性问题转化为微分不等式不存在最终正解的问题,获得了该类方程在Robin边值条件下所有解H-振动的若干充分判据.The H-oscillation of a class of second-order vector neutral partial differential equations with damped terms and continuously distributed delays were transformed into the problems of which differential inequalities haven＇t eventually positive solution by employing the method of reducing dimension with the inner product and making use of Riccati transformation and introducing parameter functions.Some criteria of sufficient conditions for the H-oscillation of all solutions of the equations are obtained under Robin boundary value condition.
