摘　　要：喷流的形成与黑洞密不可分,讨论黑洞质量与喷流功率的关系有助于研究喷流的形成与结构。从文献资料中收集了70个耀变体源,包括35个蝎虎天体(BL Lacs),35个平谱射电类星体(FSRQs)。通过样本数据分别研究两类耀变体黑洞质量与喷流功率的相关性。研究结果表明,去除集束效应后,平谱射电类星体的黑洞质量与喷流功率具有强相关性,而蝎虎天体的黑洞质量与喷流功率的相关性很弱。黑洞质量对黑洞喷流的形成具有主导作用。这些研究结果与其他方法获得的结果是一致的。The formation of jets is inseparable from black holes.Discussing the relationship between the mass of black hole and jet power is helpful to study the formation and structure of jet.Seventy blazar sources have been collected from the literature,including 35 scorpion BL Lacertae objects(BL Lacs)and 35 flat-spectrum radio quasars(FSRQs).We study the correlations between black hole mass and jet power of the two types of blazar through sample data.The research results show that after removing the beaming effect,the black hole mass of flat spectrum quasar has a strong correlation with jet power,while the black hole mass of BL Lacertae object has a weak correlation with the jet power.The black hole mass plays a leading role in the formation of black hole jet,which is consistent with previous results.
