摘要 研究具有脉冲出生、脉冲接种和时滞的SEIRS传染病模型,分析无病周期解的存在性和全局稳定性,以及传染病模型的持久性,分析控制传染病传播的主要因素。 Periodic solution of the SEIRS epidemic model with birth pulse, pulse vaccination and two time-lag is discussed. Using Fioquet theory and comparison theorem of impulsive differential equation, the existence and globally asymptotically stability of infection-free periodic solution are proven.
