文章研究了一类具有脉冲接种和脉冲剔除的SIR传染病模型的动力学性态.应用Floquet定理研究了无病周期解的局部稳定性,通过脉冲微分不等式证明了其全局渐近稳定性.
An SIR epidemic model with pulse vaccination and pulse elimination is considered in this paper. By using the Floquet theory we prove the infection-free periodic solution is local stable,and by impulsive differential inequality we show the infection-free periodic solution is also globally asymptotically stable.
