【Abstract】 A discrete viral infection model with Beddington-DeAngelis functional response is studied.By applying the comparison theorem of difference equation,sufficient conditions for the permanence of the non-autonomous model(3) is studied.Moreover,some sufficient conditions for the asymptotically stability of model(4) two equilibrium are obtained by using Jury criterion and constructing a suitable Lyapunov function.更多还原
