无治愈的非线性传染力SI模型渐近分析

Asymptotically Analysis of the Curability Nonlinear Infectivity Model

运用微分方程稳定性理论,对无治愈的非线性传染力SI模型平衡点的稳定性给出定性分析,并按纯数学意义作出其全局结构图.

By using the stability theory of the ordinary differential equations, the authors have made a qualitative analysis of the equilibrium points,stability of the curable nonlinear infection model,and the global structure in the care o f the pure mathematical meaning.
