摘要 分析了人口输入为常数时具有自然死亡和一般疾病发生率的SIRS传染病模型,得到了模型无病平衡点和地方病平衡点的存在性及其全局渐近稳定性. An SIRS epidemic model with constant input, natural death rate and general nonlinear incidence rate is analyzed. Conditions for the existence and global asymptotical stability of disease-free and endemic equilibria are obtained.
