摘    要:文章通过对具常数输入人口,死亡率和出生率的的SIS模型的确定形式与随机形式的研究,得到文中定义的基本再生数R0燮1时,传染病最终会消失,而当基本再生数大于等1时,传染病人数将稳定,传染病最终会形成地方病,最后验证了两种模型的结果是一致的。

关 键 词:随机形式  基本再生数  传染病

Abstract:This paper compares the stochastic and deterministic version of rhe SIS model with recruitment, deaths rate and birth rate, and gets that the basic reproduction number R0≤1, the number of infected people will eventually disappear. When the basic reproductive number is greater than 1, the number of infected people will eventually remain unchanged, and epidemic will become endemic. Finally the paper verifies the results for the two versions is the same.
Keywords:stochastic version  the basic reproduction number  epidemic
