摘要 研究了一类具有密度制约和治疗的SIS传染病模型,讨论了平衡点的存在性和稳定性,并利用Poincare-Bendixson定理证明系统不存在极限环. In this paper,SIS epidemic model with density-dependent and treatment is studied.We discuss the existence and stability of the equilibrium,and obtain that there does not exist limit cycle in the system by means of Poincare-Bendixson theorem.
