【摘要】 研究一类具有变化潜伏期的结核病模型,利用再生矩阵方法,得到基本再生数R0,进一步得到当R0≤1时,系统存在无病平衡点,且是全局渐近稳定的,当R0>1时,系统存在唯一的地方病平衡点,且是全局渐近稳定的.更多还原

【Abstract】 A tuberculosis model with variable latent period was studied and the basic reproduction number R0 was obtained by using regeneration matrix.There would be a disease-free equilibrium and it was globally asymptotically stable when R0≤1.Then,if R0 >1,there would be only a unique endemic equilibrium,which was also globally,asymptotically stable.更多还原
