Abstract: The triple integral computation's basic philosophy is turns the triple integral into three integrals, its key is the choice suitable coordinate system, the integral order and the limits of integration determination. The limits of integration definite key is needs to determine the range of integration on coordinate plane projection. This article used the truncation mark law to discuss the common quadratic surface on the coordinate plane projection, based on this gave by the surface encircles three-dimensional asks the law on the coordinate plane projection one kind, this kind asked method the superiority lay in does not draw the range of integration graph also to be able to determine it on the coordinate plane projection. Finally by the example explained that this kind strives for the projection the method in the computation triple integral application.

Abstract: triple integral calculation of the basic idea is to triple integral three points, the key is to choose
