【摘要】 以正项级数的比较判别法为基础,得到判别正项级数敛散性的两个判别方法,它可以作为Cauchy判别法对正项级数∑u_n,（u_n>0）,ρ=（?）u_n^n/1当ρ=1失效时的一个补充,把它称为Cauchy判别法的推广.更多还原

【Abstract】 In this paper,Base on the contrast discrimination method for series of positive terms,Two new discrimination methods for series are presented of positive terms.They can study the condition when we use cauchy discrimination arid ρ = 1,so they are called the generation of Cauchy discrimination method.更多还原
