摘　　要：The main idea and algorithm of the projection pursuit regression(PPR)based on immune evolutionary algorithm(IEA)are introduced to study the data of the Dongguan’s precipitation of 2003.The model of PPR was built to predict the pH value in precipitation.The result shows this method is steady and has good prediction precision,and has a better prediction result than that of MLR.The main idea and algorithm of the projection pursuit regression（PPR） based on immune evolutionary algorithm（IEA） are introduced to study the data of the Dongguan＇s precipitation of 2003.
