摘　　要：本文介绍了一种不用作出积分区域Ω的立体图,就可以确定三重积分累次积分积分限的定围求顶方法,进而解决了三重积分化为三次积分的问题。A method for determining the encircling boundary and finding the top technique of triple integral was introduced,which does not need to graph integral area.The method simplifies the problem of solving the triple integral into three integrals.

关 键 词：三重积分 三次积分 定围求顶
