摘　　要：诺瓦克模型作为研究乙肝感染动力学的基础模型,虽然被人熟知,其内部的信息与性质并没有充分被发掘.关注于其平衡点类型的分类,并用图呈现诺瓦克模型详细的动力学特征,得到了参数空间中分支曲线的解析表达式.尤其,当平衡点为焦点时,得到了系统固有频率与参数的依赖关系.It is well known that Nowak model is the based model for understanding the properties of hepatitis B virus infection. However its detailed properties is not enough to reveal. In this paper, we focus on the classification of the steady state, present an integrated and detailed picture of the dynamics of this system, get the analytical expression of bifurcation curves in parameter space.Especially, we study the intrinsic frequency of the system when it approaches to ＇focus＇, calculate the dependence of it on parameters.

关 键 词：诺瓦克模型 全局稳定 分支曲线 轨道频率
