摘要
在几何薄光学厚稳态吸积盘的假定下，通过标准吸积盘理论，讨论了其所具有的黑体谱性质，并且计算了吸积盘的有效温度．所得的发射谱特征较好地符合Ｐｒｉｎｇｌｅ等人的结论．计算的吸积盘的表面温度比较Ｓｈａｋｕｒａ和Ｓｕｎｙａｅｖ所得结果要高１－２个数量级，这一结果说明吸积盘的辐射不仅位于紫外波段， 而且可能位于 Ｘ射线波段．
By using standard accretion disk theory, the black body spectrum of geometrically thin and optically thick accretion disks is discussed and the effecive temperature of accretion disk is calculated. It is found that the characters of emission spectrum fairly accorded with the Pringle's result and the surface temperature is 1-2 order higher than the one of Shakura and Sunyaev's conclusion. The results showed that the radiation of accretion is not only in the ultraviolet wave band but also in the X-ray wave band.
