摘要
本文建立了一类具有脉冲和双时滞的离散SIRS传染病模型,并给出模型无病平衡点全局吸引和疾病持久的充分条件.
In this paper, a discretized SIRS epidemic model with pulse vaccination and two time delays are taken in- to consideration. Sufficient conditions for global attractivity of an infection-free periodic solution and permanence of the model are obtained.
