中文摘要：

主要以2013年10月份哈尔滨雾霾事件为背景,对哈尔滨的雾霾天气进行了模拟,根据污染的情况,建立了具有Dirichlet边值条件的三维反应扩散方程数学模型,并应用分离变量法得到其解析解.

英文摘要：

In this paper, the haze weather in Harbin is simulated by focusing on haze events in October 2013 in Harbin. According to the situation of the pollution, the three -dimensional reaction- diffusion equation model with Dirichlet boundary conditions is obtained and its analytical solution is gained by the method of separated variables.
