摘要
简单催化模型常用于确定易感人群年新感染率与感染率之间的关系，但局限于易感人群年新感染率与年龄无关．为解决此局限性，对模型做了相应的改进，并应用于1992年肝炎流行病学调查中乙型肝炎病毒感染宰的拟合，结果表明，改进模型比简单催化模型优越。
Simple catalytic model is used to determine the relationship between the new-annual infection rate in susceptibles and the infection rate of infectious diseases, but thepremise of the model application is that new annual infection rate in susceptibles is not re-lated to age. This paper improves Simple Catalytic Model, analyzes the data of HBV infec-tion rate from hepatitis epidemiologic investigation in 1992. The result shows the improvedmodel is superior to Simple Catalytic Model.
