| 摘 要： | 收集了109个blazar天体（HBLs 51个,LBLs 40个,FSRQs 18个）的相关观测数据,对该样本的黑洞质量、吸积率、热光度和红移的分布规律进行了统计分析,讨论了吸积率与热光度、黑洞质量与热光度之间的关系,结果发现：（1）存在一个从FSRQs经LBLs到HBLs的演化序列;（2）爱丁顿吸积率是影响blazar天体三个子类之间演化序列的主要因素;（3）blazar天体三个子类的热光度需要进行多普勒效应改正.

| Abstract: | In this paper, we collected 109 samples of blazar（51 HBLs, 40 LBLs, 18 FSRQs）, then analyzed the statistical distributions of black hole mass,accretion rate,bolometric luminosity and redshifts of the samples,and discussed the relationship between the black hole mass and the bolometric luminosity,and between the accretion rate and the bolometric luminosity. At last,we drew the following conclusions： （1）There are an evolutionary sequence of properties from FSRQs through LBLs to HBLs; （2）The main reason for the evolutionary sequence of three subclass of blazar may be Edditon ratio rather than black hole mass;（3）The observed bolometric luminosity must be corrected for the Doppler effect. |
