递减级数收敛性的两种判别法

Two Convergence Criteria for Decreasing Series

根据单调递减级数的阶A(n),得出类似于正项级数的比较判别法和根值判别法,用于判定较复杂的单调递减级数的收敛性。

The comparison creterion and the cauchy one were obtained, based on the degree A（n）, of monotone decreasing series, which was similar to that of the positive term series. These two criteria were used to determine the degree＇s convergence of the monotone decreasing series.
