我们计算由 X 射线集中照射的吸积盘的 UV 和 X 射线连续光谱和偏振。圆盘的电离结构的计算是使用Ross & Fabian描述的数字代码进行的，而倾斜效应和偏振是通过求解偏振辐射的传递方程来计算的。史瓦西度规中的一般相对论效应也被考虑在内。我们获得的光谱可以解释一些活动星系核和几个候选星系黑洞的X射线观测，其中铁线强度和反射连续体的形状似乎与中性物质的再处理不一致
We calculate the UV and X-ray continuum spectrum and polarization from an accretion disc centrally illuminated by X-rays. The calculation of the ionization structure of the disc is performed by using the numerical code described by Ross & Fabian, while the inclination effects and the polarization are calculated by solving the transfer equation for polarized radiation. The general relativistic effects in the Schwarzschild metric are also taken into account. The spectra we obtain can explain the X-ray observation for some active galactic nuclei and several Galactic black hole candidates, for which both the iron-line intensity and the shape of the reflection continuum appear to be inconsistent with reprocessing from neutral matter
