摘要
探讨具偏差变元的某些抛物与双曲偏微分方程解的振动性。在定理２与定理５中扩充了傅希林等在１９９４年发表的与崔宝同等在１９９６年发表的文章中的定理，从而得到这些方程的解为振动的充分条件。
Abstract This paper discusses the oscillation of solutions of some parabolic and hyperbolic partial differential equations wtih deviating arguments. By extending some theorems in and , the suffcient conditions for the oscillation of the solutions of these equations is get. The main results are theorems 2 and 5.
