本文建立了一阶时滞微分方程和一阶超前微分方程解的相邻零点间距离的估计，其中P ∈ C（[t0，∞），[0，∞）），τ ∈ R+.我们的研究结果改进了文献中最近的结果。
In this paper, we establish some estimates for the distance between adjacent zeros of the solutions of the first order delay differential equation and the first order advanced differential equation where P ∈ C([t0, ∞), [0, ∞)) and τ ∈ R+. Our results improve recent results in the literature.
