摘    要:在标准吸积盘辐射模型的基础上,考虑了不同的质量吸积率、不同的无量纲旋转参数a(中心黑洞为克尔黑洞)、最小稳定轨道半径处存在的约束(产生一个矩)和吸积盘表面磁场的存在(喷流辐射与吸积盘辐射之间存在一定的耦合)对吸积盘辐射的影响。结果表明,中心黑洞为正旋转的克尔黑洞比史瓦西黑洞辐射的峰值及峰值频率大,负旋转的克尔黑洞比史瓦西黑洞辐射的峰值及峰值频率小,质量吸积率越大峰值和峰值频率变大,无量纲黑洞旋转参数a越大峰值与峰值频率越大,喷流辐射能量和吸积盘辐射能量之比越大峰值和峰值频率越小,辐射效率越大峰值和峰值频率越大。

关 键 词:黑洞  吸积盘  喷流  辐射效率

Abstract:This paper considers effects of the accretion disks radiation with different mass accretion rate, different dimensionless rotate parameters a (central black hole is Kerr black hole), the constraints of the minimum stable orbit radius (produces a torque), the magnetic field existing on the surface of accretion disk (the coupling of jets radiation and the accretion disks radiation) based on the standard radiation accretion disk model. It can be concluded that black hole type, mass accretion rate, dimensionless black hole rotating parameters, the radio of jet radiation energy and accretion disk radiation energy, and radiation efficiency parameters have certain effect on accretion disks radiation through theory graphs.
Keywords:Black hole  Accretion disk  Jet  Radiative efficiency
