摘要
研究了一类具有年龄和病程的传染病模型,在总人口达到平衡状态时,建立了相应的等价模型,并利用偏微分方程的特征理论给出了模型平衡解满足的积分方程组.
In this paper,a class of infectious disease models with age and course of disease is studied,when the total population reaches equilibrium,the equivalent model of the model is established,and the integral equations satisfied by the equilibrium solution of the model are given by using the characteristic theory of partial differential equations.
