摘要
本文研究一阶中立型时滞微分方程解的零点的分布，去掉了已有文献中对系数较强的限制条件，获得了这类方程振动解的相邻零点间距离的估计，并且改进和推广了文献中的一些知结果．
The purpose of this paper is to study the distribution of zerose of solutions of the neutral delay differential equations. An estimate is established forthe distance between adjacent zeroes of the solutions of such equations underless restrictive hypotheses on the variable table coefficients. The results obtainedimprove and extend some known results in the literature.
