【Abstract】 In this paper it is considered some epidemic model with constant contact.Upper and lower solution method and Liapnuov functional method are used to discuss the stabilities of the disease-free equilibrium and the endemic equilibrium.Sufficient conditions are given such that the disease-free equilibrium and the endemic equilibrium are stable.更多还原
