Abstract:This paper is based on the nature of the function itself,it will do the study and summary of a series of typical significance methods to solve the Generalized Integral problem.There are not only some basic methods use Integration by parts and Change element integral,but also some ingenious methods use the symmetry of the function,the nature of the，function,the commencement of the Taylor formula in this paper.

Key words : Generalized Integral；summerise method；Parametric variable
