摘要
通过对一类中立型泛函微分方程的振动性的研究，利用积分、下极限和函数代换的技巧与方法，获得了该方程解的振动性的一个新的准则，该准则改善了对方程的条件限制。推广了现有文献[1～3]的一些结果。
Through studying the oscillation of a class of neutral functional differential equations and using the methods and techniques of integration and inferior limit and functional substitution, a new sufficient criteria has been obtained for the oscillation of the equations＇ solutions. This criteria can improve the restriction of the conditions for the equations. Some results of references[1-3] have thus been extended.
