摘要
在已知的四种黑洞吸积盘模型中，Ｓｈａｐｉｒｏ－Ｌｉｇｈｔｍａｎ－Ｅａｒｄｌｅｙ（ＳＬＥ）盘是不稳定的，细（Ｓｌｉｍ）盘研究得还不够，较为成功的是最早建立的Ｓｈａｋｕｒａ－Ｓｕｎｙａｅｖ盘（ＳＳＤ）和近年成为热点的径移主导吸积流（ＡＤＡＦ）。ＳＳＤ和ＡＤＡＦ看来分别适用于吸积流中离黑洞较远和较近的区域，故二者的结合即ＡＤＡＦ＋ＳＳＤ模型有望对黑洞吸积流作出较为完整的描述，但这个结合模型也还有不少未解决的问题。
There are four known models of black hole accretion disks, of which the Shapiro-Lightman- Eardley (SLE) disk is unstable, the slim disk has not been studied in detail, and quite successful are the Shakura-Sunyaev disk (SSD) that was first established and the advection-dominated accretion flow (ADAF) that has received much attention in recent years. It seems that SSD and ADAF are adequate to the outer and the inner region of the black hole accretion flow, respectively, thus their combination, i.e. the ADAF+SSD model is likely to be able to give a complete description of black hole accretion flows, although there are still many open questions regarding this combining model.
