根据B型肝炎的传播特点,建立了带有生理年龄和感染年龄的模型. 假定传染率依赖个体的生理年龄和传染年龄,疫苗有一定的有效期, 得到了无病平衡态稳定的条件.

Based on the infection characteristics of Hepatitis B, a mathematical model with chronological-age and infection-age was developed. Assuming that infection rate depends on individuals' chronological age and infection age and that the vaccination has definite lifetime, the condition of the stability of the infection free equilibrium was obtained.
