HU Yu(Guangdong Vocational College of Industry & Commerce,Guangzhou Guangdong 510510,China)  
The paper aims at the partial least square PLS dimensiona reduction and quadratic discriminant analysis(QDA),discriminant methods: to do the data analysis on gene chip(micoarray).PLS,which has been developed recently,is an efficient method for analyzing numerous data.It can extract the features much closer to the gene data expression of originality.It shows that when PLS is pre-disposal of the dataset,the accuracy of classification of gasoline is improved noticeably.
