摘要
本文绘出了以下系统所有解振动的新的充要条件：这里aif，Pl，τl为实常数且Pl＞0.τl＞0．另外,我们就此条件做了进一步的工作．
New sufficent and necessary condition is obtained for all solutions of the system x'(l) = ,n to be oecillatory, where alj,Pl and τl are real constants with Pl>0 and τl>0.Furthermore,some special works have been done according to the condition.
