AA kind of HBV infection model with nonlinear incidence rate was studied.By constructing Lyapunov function and using the second additive compound matrix,it was proved that the infection-free equilibrium of system is globally stable when R0 ≤ 1 ; and the endemic equilibrium of system is globally stable when Ro > 1.
