| 摘 要： | 针对类似丙肝这种具有较长慢性阶段的流行病问题,依据仓室建模思想,建立并研究了一类具有变化的总人口数的含有易感者类、潜伏期类、染急性病者类和染慢性病者类的SEIS流行病模型.借助基本再生数R0和基本取代率R1,讨论了上述4类人群的指数变化率.

| Abstract: | A model with acute and chronic stages in a population with varying Exponentially size is proposed.The variables of the standardized model denote respectively the proportions of susceptible,exposed,infected acutely and chronicly in the total population.The variational rate of four style of population is discussed with the help of a basic reproduction number R0 and a basic ratio of replacement R1. |

| Keywords: | epidemic model variational rate basic reproduction number |
