【Abstract】 A predator-prey system with two time delays and stage-structure for the predator is investigated.Using the method of characteristic root,the comparison theorem of differential equation and the theory of limit system,the sufficient conditions are obtained for the globally asymptotically stability of the equilibria.Numerical simulations are carried out to illustrate the main results.更多还原
