研究一阶时滞微分不等式x′(t)+q(t)x(t-δ)≤0正解的最大存在区间。作为应用，我们对几种时滞微分方程的解的相邻零点之间的距离建立了一些更好的估计。
The maximum existence interval of positive solutions of first order delay differential inequality x′(t)+q(t)x(t-δ)≤0 is investigated. As applications, we establish some better estimates for the distance between adjacent zeroes of the solutions of several kind delay differential equations.
