| 摘 要： | 本文根据文1，2]三个类星体表的3941个类星体作统计分析，发现在发射红移Zem1．4—3．2范围内吸收线较多，尤其在Zem1．8—2．4范围内明显增加；同时在Zem1．4—2．8范围内出现吸收线红移Zab＞Zem的现象．结果表明，在Zem1．8—2．2间隔内的类星体活动性加剧，似可以说反映了类星体与环境相互作用的演化效应．

| Abstract: | A stahshcal analysis of 3941 QSOs in three tables given by Hewitt and Burbidge in papers 1] and 2] has ho camed out, finding out considerable absorption lines in Zem range of l'4-- 3'2 and remarkable in~sement of them in the As interval of l'8 -- 2'4.Meantime, absorption redshifts Zab>Zem happen in the Zem range of 1.4 - 2.8. This shows that the activities of QSOs enhance in the Zem interval of 1.8 - 2.2.This seems to reflect the evolution of QSOs with the interaction of their environment. |
