传染病模型

Infectious Disease Model

传染病常在世界各地流行,建立传染病的数学模型,分析其变化规律,防止其蔓延是一项艰巨的任务.传染病在传播期间其地区总人数不变时已建立了很好的数学模型.文章对其用微积分的方法进行了分析,并在该基础上进行了修正,建立了传染病传播期间其地区总人数变化的数学模型.

The infectious disease is prevalent usually in the word.Building mathematical models of infectious diseases,analysis of its variation,preventing its spread is a difficult task.Spread of infectious diseases during the same time the total number of its regions have established a good mathematical model.It is analyzed by the method of calculus fluxion.,amended it,and established mathematical model during the spread of infectious diseases on the basis of changes in the total number of in the region.
