| 摘 要： | 本文对CfA样本中的属群星系进行了最近邻间距分析,发现在最近邻距离小于20kpc的星系中存在明显的Seyfert核超(即其中Seyfert星系所占比率高出平均值约3倍)。这表明近距星系的存在可能是产生Seyfert核活动的有利环境。

| Abstract: | A neighborhood statistic study has been done for the galaxies inside the groups of CfA redshift sample. It was found that the ratio of Seyferts to non-Seyferts, when the distance of the nearest neighbor is less than 20kp, is 3 times higher than the average one. It shows that the existence of the close companions is the favoring environment to triggle the occurences of the Seyfert activities. |
