摘　　要：通过求非负函数f(x)的有关极限判断广义积分∫+a∞f(x)dx的敛散性,给出了非负函数的瑕积分敛散性的判别法.How to judge the divergence and convergence of the generalized integral ∫^＋∞ αf（x）dx is discussed through finding the related limit of non-negative function, and a method of judging the divergence and convergence of the flaw integral of a non-negative function is given.

关 键 词：非负函数 敛散性 广义积分 瑕积分
