摘要
讨论了一类具有脉冲接种和非线性接触的SIRS传染病模型,利用F loquet和小振幅扰动理论,证明了无病周期解在一定条件下该模型是全局渐近稳定的.
A kind of SIRS epidemic model with satured incidence and impulsive vaccination is presented. By using the Floquet theory of impulsive equation and small amptitude perturbation skills, it is proved that the disease - free solution is globally asymptotical stable under certain condition.
