类星体的空间分布和与星系的成协

SPATUAL DISTRIBUTION OF QUASARS AND ASSOCIATION WITH GALAXIES

采用最新的较完备的类星体总表，用数理统计的Ｘ２检验的方法，分别选取泊松分布和伽马分布，分析了类星体红移和星等的大尺度分布，并且考察了室女星系团天区类星体与星系团中亮星系成协的可能性。得到初步的结果：类星体就整体来说其红移和星等在各种尺度上的分布是不均匀的；类星体与星系团中亮星系普遍成协的可能性不显著，但局部区域的成协性是存在的。

On the base of the complete and update quasar data, the distribution of redshift and magnitude is analysed statistically, the possible association of quasars with bright galaxies in the Virgo cluster region is discussed as well. It is concluded that: ①The distribution of redshift and magnitude of quasars on different scales is non- uniform.② in the Virgo cluster region there is less evidence for quasars associating with bright galaxies in the scale of 100 square degree.However, the associate evidence in the scale of 25 square degree is significant.
