目前的线发射吸积盘自洽模型能够解释在一小类活动星系核中观察到的特性，其主要对象是 Arp 102B 和 3C 390.3，其双峰发射线被归因于开普勒盘。改进了相对论性开普勒圆盘线轮廓的计算，概括为包括各种发射率定律以及由于电子散射或湍流导致的局部展宽，适合 Arp 102B；对外部薄盘与扩展的各向同性照明源所呈现的立体角的分析和数值计算表明，也满足了盘线发射的能量预算要求。 27 参考文献
The prime objects of the present self-consistent model of a line-emitting accretion disk able to account for the properties observed in a small class of AGNs are Arp 102B and 3C 390.3, whose double-peaked emission lines have been attributed to a Keplerian disk. Improved calculations of the line profile of a relativistic Keplerian disk, generalized to include a variety of emissivity laws as well as local broadening due to electron scattering or turbulence, are noted to fit Arp 102B; analytic and numerical calculations of the solid angle presented by the outer thin disk to an extended isotropic source of illumination demonstrate that the energy budget requirements for line emission from the disk are also satisfied. 27 refs.
