摘　　要：通过讨论非负递减函数自身的性态,建立了非负递减函数无穷积分敛散性几个新的判别方法,并利用正项级数的敛散性判别法给出了证明.Some new methods for discriminating converngence and divergence about nonnegative monotone decreasing functions infinite intrgral are given by studying the feature of nonnegative monotone decreasing functions,and proved by using of the methods for discriminating converngence and divergence about positive series.

关 键 词：无穷积分 敛散性 判别法
