Global exponential stability theorems are given by using a method based on delay differential inequality.
在分析无条件全局指数稳定性时，我们将时滞微分不等式引入到稳定性的研究中。

This paper establishes a delay differential inequality with varying coefficient and varying delay.
本文首先建立一个变系数变时滞微分不等式。

In this paper, a delay integral in quality are established. Applying this inequality to study the stability of large scale neutral differential systems, some simple stability criterion are obtained.
