摘    要:收集了209个活动星系核(46个平谱射电类星体,78个BLLac天体,85个射电星系)样本,估算出爱丁顿吸积率,讨论了黑洞质量、热光度、红移量和爱丁顿吸积率之间的关系,得出了以下结论:(1)活动星系核的一个演化序列为:平谱射电类星体(FsRQ)——BL Lac天体——射电星系(RG)的演化;(2)三类星体的中心黑洞质量、红移量和热光度有较大差异:皆为FSRQ〉BLLac〉RG;(3)吸积率与热光度之间的相关性很强,吸积率的变化将导致热光度的变化。

关 键 词:活动星系核  中心黑洞质量  红移量  热光度  爱丁顿吸积率

Abstract:In this paper,we collected 209 active galactic nuclei (46 flat spectrum radio quasar,78 BL Lac objects,85radio galaxy ) samples, estimated the Eddington accretion rate,and discussed the relationship of the mass of the black hole, bolometric luminosity,the redshift and Eddington accretion rate, drew the following conclusions: (1) a sequence evolution of active galactic nuclei is: flat spectrum radio quasar-BL Lac obiects -radio galaxy; (2) the masses of black holes,red- shift and the bolometric luminosity has bigger difference: FSRQ 〉BL Lac 〉 RG ; (3) there is a strong correlation between the bolometric luminosity and the accretion rate , the accretion rate changes will lead to changes in the bolometric luminosity.
Keywords:Active galactic nuclei  The mass of black hole  Redshift  Bolometric luminosity  Eddington accretion rate
