借鉴数论方法中的密率论 ,给出判别正项级数敛散性的密率判别法 。
With the help of density theory in number theoretic method;method of density is provided in the paper to discriminate convergence or divergence of positive term series.This method is particularly suitable for dliscrimination of convergence or divergence of series,which is difficult or impossible to be given expression of general term.
