摘要 文章利用Blazar中γ射线中光深对黑洞质量的依赖关系,搜集了blazar的相关观测数据,包括X射线和γ射线的流量以及短光变时标,分析了33个blazars,得到中心黑洞质量,辐射区距离,辐射角以及多谱勒因子等重要参量.结果表明:中心黑洞质量的范围是(1.32~151.49)107M⊕(M⊕是太阳质量),辐射区范围(16.8~992.9)Rg(Rg是Schwild半径),辐射角的范围是1.31°~56.34°,多谱勒因子的范围0.21~4.11. In this paper, we avail the dependence of optical depth on black hole, collect the data, including optical timescales, the flux of X-ray and γ-ray, analyze 33 blazars, and obtain the central black hole, the radiational region, the radiational angle, the Doppler factor. The results show that : the coverage of central black hole mass is ( 1.32 - 151.49 ) 107Mo ( Mo being the solar mass ), the coverage of region is ( 16. 8 - 992. 9 ) Rg ( R, being Schwild radius), the coverage of angle is 1.31° -56. 34° , the coverage of Doppler factor is 0. 21 N4. 11.
