摘要
讨论了一类含确定时滞的SIS流行病模型 ,利用李亚普诺夫泛函的方法 ,得到了无病平衡点和地方病平衡点全局稳定性的结论 。
An SIS epidemic model with discrete delays is discussed, by means of liapunov functional, some sufficient conditions of global stability to endemic equilibrium and disease free equilibrium have been obtained. The influence of time delay on the stability of equilibria is displayed.
