【Abstract】 In this paper,the dynamical behaviors of a predator-prey model are investigated.The conditions of existence,local stability and bifurcation for the steady-states are obtained and the periodic solution of the Hopf type is put forward.The existence of multiple Hopf bifurcation point is also examined with suitable values of parameters.更多还原
