摘　　要：本文讨论一类带有偏差变元的二阶偏微分方程组解的振动性 ,将多维问题转化为一维问题 。In this paper, the authors discuss the oscillation for the solution of the system of second order partial differential equations in a kind of deviating argument, and some sufficient conditions are obtained for the oscillation for solutions system of second order partial differential equations by converting many dimensions into one dimension.
