具有常数输入率的SIS传染病模型

摘要

A SIS infectious disease model with constant input rate is studied. Existence of two kinds of this model’s equilibrium points and their local and global stability are discussed. The strategy of controlling disease’s development is obtained by qualitative and quantitative analysis.%　　研究了具有常数输入率的 SIS 传染病模型，讨论了该模型两类平衡点的存在性及平衡点的局部稳定性和全局稳定性，通过定性定量分析，得到了控制该疾病发展的对策。
