摘　　要：红移、中心黑洞质量和吸积率是活动星系核演化的重要参数.利用反响映射法计算了172个类星体和Seyfert星系样本的中心黑洞质量,并分析了中心黑洞的质量、红移、爱丁顿吸积率的分布,进而验证了从类星体过渡到Seyfert星系的演化.Many people have discussed the property of AGNs （active galactic nuclei）. The variation of spectrum, the correlation of multi-wave bands and the property of polarization give good information for studying intrinsic correlation of components and its position. To date, the redshift and the Eddington rate and the masses of black hole are the basic properties of active galactic nuclei. In this paper, firstly calculated the mass of black hole and the Eddington rate of 172 samples using the reverberation mapping method, secondly statistical distribution of the black hole masses and the Eddington rate of Seyfert Galaxies and Quasars, thirdly investigated the relation between redshift and Eddington rate and analysed the relation between Eddington rate and the black hole mass and discussed the relation between the redshift and the masses of black hole as well as the relation between the redshift and the Eddington rate, since the evolution essential of AGNs is the change on the timescales of the universe, and the redshift plays an important role in the evolution of AGNs. From these analyses, this paper found that the black hole masses and the redshift of AGNs change with the development of Eddington rate. Through these results, the paper has made an initial statistical research for the AGNs evolution, and found the transformation from Quasar to Seyfert galaxy.
