摘要:
本文介绍了一类垂直传染带脉冲免疫以及非单调发病率的SIRS传染病模型，首先利用Floquet定理，脉冲比较定理以及迭代法给出了无病周期解的全局渐近稳定的条件，得出当且时，无病平衡点是全局渐近稳定的结论。其次通过使用比较定理，证明了系统持续的充分条件。In this paper, we investigate an SIRS epidemic model with vertical transmission and pulse vaccination and non-monotonic incidence rate. First, we obtain the condition for which the disease-free periodic solution of the epidemic model is globally asymptotically stable when and by Floquet theorem, impulsive comparison theorem and iteration method. Second, permanence of this system is presented by comparison theorem.
