在超大质量黑洞的非饱和康普顿盘吸积模型框架下(与同步康普顿模型相反)，比较了Shapiro，Lightman和Eardley(1976)的热内盘模型与具有平衡传导和康普顿损耗的盘-日冕模型。在超大质量情况下，两者都可以产生至少约10亿K的电子温度，但都承诺会有其他可观察到的区别。圆盘日冕的夹层结构自然地解释了为什么康普顿化是不饱和的。
Within the framework of unsaturated Compton disk accretion onto a supermassive black hole as a model for power-law active-galactic-nuclei X-ray sources (as opposed to the synchro-Compton model), the hot-inner-disk model of Shapiro, Lightman, and Eardley (1976) is compared with the disk-corona model with balanced conduction and Compton losses. Both can generate electron temperatures of at least about 1 billion K in the supermassive case but promise other observable distinctions. The sandwich configuration of the disk corona provides a natural explanation of why Comptonization is unsaturated.
