摘　　要：对一类具有免疫损害项的带时滞的病毒感染模型进行了动力学分析,研究未感染平衡点的全局稳定性,并给出感染平衡点产生Hopf分岔的充分条件;数值模拟验证了主要分析结果,从而解释了免疫反应的复杂性.The dynamic behavior of a delayed viral infection model with an immune impairment term is analyzed. The globally stability of the viral free equilibrium is investigated, and the sufficient conditions of the existence of Hopf bifurcation around infected equilibrium are studied. Numerical simulations are carried out to illustrate the main results, which can explain the complexity of immune response,
