从旋转黑洞周围的吸积盘发出的荧光线被检查。给出了不同倾角、克尔参数和圆盘参数下的各种型号的线形。如果发射区域高度局域于内部，r < 20 GM/c 2，则黑洞旋转造成的差异出现在谱线轮廓上。否则，由于光子从更大的半径发射，差异被隐藏，其中辐射的传播和圆盘结构几乎与Kerr参数无关
The fluorescent line emitted from an accretion disc around a rotating black hole is examined. The line profiles for various models with inclination angle, Kerr parameter and disc parameters are given. If the emitting region is highly localized to the inner part, r < 20 GM/c 2 , the difference due to the black hole rotation appears in the line profiles. Otherwise, the difference is hidden due to photons emitted from larger radii, where the propagation of the radiation and the disc structure are almost independent of the Kerr parameter
