摘要 研究一类具常数接触率的传染病模型,用特征空间方法和Liapnuov泛函讨论了正常数稳态解的渐近行为,得到了正常数稳态解全局稳定的充分条件。 In this paper, an epidemic model with constant contact rate is considered. Eigenspace method and Liapnuov functional method are used to discuss the stabilities of positive constant stable soulation. A sufficient condition for the system to have a positive globaliy asymptotically stable solution is obtained.
