一类具有脉冲接种的非自治SEIV传染病模型的动力学分析

摘要

In this paper,a nonautonomous SEIV epidemic model with pulse vaccination is proposed and studied.The basic reproductive number R0 is obtained,and the threshold conditions for the permanence and extinction of the disease are established.%本文提出并分析了一类具有脉冲接种的非自治SEW传染病模型.求出了关于传染病灭亡和持久的阈值R0.
