Abstract
The predator-prey model with constant immigrant and nonlinear rate was analyzed by differential equations stability theory.The boundedness of solutions and the existence of the equilibrium were studied by applying the theory of differential inequality.The sufficient conditions of local asymptotic stability of the equilibrium were obtained by the Routh-Hurwitz criterion. And the global stability of the equilibrium was analyzed by constructing appropriate Lyapunov functions
that is the conditions of the disease existent or not.
