中文摘要：

喷流的形成与黑洞质量及黑洞自旋之间存在着很大关系．讨论黑洞质量及黑洞自旋与喷流能量的关系对喷流形成及结构的研究有着重要的意义．从文献资料中收集了65个射电类星体源．这些源包含了35个陡谱射电类星体（SSRQs），30个平谱射电类星体（FSRQs）．通过样本数据研究黑洞质量及黑洞自旋与喷流能量的相关性．研究结果表明：（1）65个射电类星体的黑洞质量与喷流能量存在明显的相关性，这与Zensus所得出的结论相同；（2）65个射电类星体的黑洞自旋与喷流能量存在相关性．尤其在爱丁顿磁场条件下（B=BEDD），黑洞自旋与喷流能量的相关性最为明显，其相关系数要比黑洞质量与喷流能量的相关系数高；（3）陡谱射电类星体与平谱射电类星体的自旋数据分布存在一定差异；（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自旋能量存在关系．黑洞喷流的形成很可能是黑洞质量与黑洞自旋共同作用的结果．这些研究结果与其他方法获得的结果是一致的．

英文摘要：

Supermassive black holes are described by their mass and spin. It is very important to do the correlation analysis among black hole mass, spin, and jet power. We collect 65 radio loud quasar sources. The sample includes 35 Steep Spectrum Radio Quasars （SSRQs） and 30 Flat Spectrum Radio Quasars （FSRQs） with redshifts ranging from about zero to two. We present the correlation analysis of jet power with black hole mass and spin, under three assumptions of the magnetic field strength. Our conclusions are as follows： （1） The black hole mass has strong correlation with jet power; （2） The black hole spin also has strong correlation with jet power especially when the magnetic field strength B = BEDD, where BEDD is the Eddington magnetic field strength; （3） There are a few differences between the distributions of the black hole spin for SSRQs and FSRQs; （4） The results suggest that the black hole jet may get the energy from spin energy, which is consistent with previous results.
