摘　　要：继续考虑特征标的零点对有限群结构的影响,并给出了特征标表中每列至多有两个零点的有限群的分类,从而完成了特征标表中每列至多p(p是群的阶的最小素因子)个零点的有限群的完全分类.The authors continue to classify the finite groups by investigating the zeros in columns of their character tables and obtain the classification of the finite groups with at most two zeros in each column of their character tables, which completes the classification of the finite groups having at most p zeros in each column of their character tables, where p is the smallest prime divisor of the order of a group.
