中文摘要：
偏泛函微分方程来源于物理学、生物学、工程学等学科领域中众多的数学模型，具有强烈的实际背景．振动性理论作为偏泛函微分方程定性理论的重要分支之一，对其进行研究具有极大的理论意义与实用价值．笔者研究一类高阶非线性时滞偏微分方程组的振动性，利用Green定理和Riccati变换，获得了该类方程组在两类不同边值条件下所有解振动的若干充分性判据，并通过一些实例加以阐述．所得结果为解决上述学科领域中的实际问题提供了数学理论基础．
英文摘要：
Partial functional differential equations come from many mathematical models in physics, biology, engineering and other fields, which have strongly practical background. The oscillation theory is the one of the important branches of qualitative theory of partial functional differential equations. Therefore, it is of great theoretical and practical value to research the oscillation of partial functional differential equations. The anthors study the oscillation of the systems of a class of high order nonlinear delay partial functional differential equations. By using Green＇ s theorem and Riccati transformation, they obtain some sufficient criteria for oscillation of all solutions of the systems under two kinds of different boundary value conditions, which are illustrated by some examples. These results offer the foundation of mathematical theory for solving the practical problems of the above fields.
