摘要
讨论了具有两阶段结构的自治SIS传染病系统,证明了该系统的边界平衡态和正平衡态的全局渐近稳定性,得到了使其渐近稳定的阈值.
A SIS Epidemic system with two stage-structure is discussed by applying the stability theory. It comes to a conclusion that the global asymptotic stability is deduced about the equilibrium point of the system. The threshold is obtained at the time of the asymptotic stability of equilibrium point.
