摘要
根据传染病动力学,建立了一类具有双线性感染率和免疫接种的SIRS传染病模型.利用微分方程定性和稳定性理论,讨论了平衡点的性态和全局渐近稳定性,得到了一些新结果.
Based on infection dynamics,a class of SIRS infection model with double linearity infection rate and immunity vaccines is established.By using qualitative theory and stability theory of differential equations,the behavior of equilibrium point and global progressive stability of its equilibrium point are discussed,some new results are obtained.
