XIE Chen-long;ZHAO Xiang-qing;LIU Ai-min;Department of Mathematics,Zhejiang Ocean University;Educational Technology Center,Yulin Normal University;  
Compare principle is the basic method for improper integration(infinite series),not only because it is convenient to use but also because it is the base for proof of other methods.By relaxing limits with up-lower limits in assumption condition,Compare principle is generalized.We give some examples in the last section from which the advantage of the generalized compare principle is shown.
