喷流的形成与黑洞吸积向来密不可分。分析黑洞吸积率与其喷流能量的相关性对研究黑洞内部结构以及喷流形成的具体原因具有重要的意义。从文献资料中收集了24个数据源,这些源包含了13个射电选BLLac天体(RBL)和11个平谱射电类星体(FSRQs)。通过样本数据研究黑洞吸积率与喷流能量以及γ射线流量密度的相关性。研究结果表明:(1)24个活动类星体的吸积率与喷流能量存在明显的相关性,这与Allen等得出的结论相同;(2)射电选BLLac天体与平谱射电类星体的喷流能量分布存在一定差异;(3)射电选BLLac天体的吸积率与γ射线流量密度相关性并不明显,但平谱射电类星体的吸积率与γ射线流量密度之间具有一定的相关性;(4)研究结果进一步证明了喷流能量不仅与黑洞质量有关,同时也很可能与黑洞的吸积存在关系。黑洞喷流的形成很可能是黑洞质量与吸积共同作用的结果。这些研究结果与其他方法获得的结果是一致的。
The balck holes in the cores of galaxies and galaxy clusters are commonly observed to be associated with powerful relativistic jets. We collected 24 AGN sources in this article. The sample includes 13 RBLs and 11 FSRQs. We studied the correlation between the accretion rate and the jet power. We also made the correlation analysis between the accretion rate and the ~/flux density. Our conclusions are as follows : ( 1 ) The black hole accretion rate has the strong correlation with the jet power; (2) There are a little differences between RBLs and FSRQs for the distribution of the black hole jet power; (3) The γ flux density has the different correlation with hole jet may obtain the different ways. the jet power for RBLs energy from the spin and FSRQs; (4) It is suggested from our result that the black accretion which is consistent with other results obtained in
