In this paper, the author finds the discriminating method of "ratio value of adjacent terms "for Convergence-divergence of the positive seriea of this kind ( with all terms monotone decreasing ) and the limit form by using " ratio value of adjacent terms". Furthermore , the author also finds some concrete discriminating methods used for judging the convergence -divergence of the positive series of the same kind. 本文利用“跃项比值”,给出了一类(各项单调减少的)正项级数敛散性的“跃项比值”判别法及其极限形式.据此,又得到了一些具体的判别法,用于判断此类正项级数的敛散性. In this paper, the author discusses the previous essay Discrimination Method of "Ratio Value of Adjacent Terms" for Convergence-Divergence of the Positive Series written by himself, presented the Comparative Discriminating Method "Ratio Value of Adjacent Terms" for Convergence-Divergence of the Positive Series, and makes the discriminating method of ratio value of adjacent terms infinitely refined. 本文是对本人前作《正项级数敛散性的“跃项比值”判别法》的再探,给出了正项级数敛散性的“跃项比值”比较判别法,进而将“跃项比值”判别法无限精细化。
