摘要 在一定的假设下,建立了一类离散的SIR传染病模型,借助差分方程理论,分析得到易感者和染病者的最终状态,并发现染病者数量的变化规律及相应的阈值条件。 Under some assumptions, a discrete - time epidemic model is established. By means of theory of differential equation, the ultimate states of the susceptible and the infective are obtained, and the varying tendency of the number of the infective and the corresponding threshold condition are found.
