摘要
本文用数值方法讨论了吸积盘谱与黑体谱的形状和谱指数。结果表明:对于吸积盘用F_v∝v^(1/3)作为其特征谱是不合适的;同时Frank等(1985)所得到的解析式F_v∝v^2也是不正确的。
In this paper,the spectra of an accretion disc and the shape and spectral index of a black body are studied by means of the numerical method.It can be obtained from the figures in this paper that the spectrum of the accretion disc is significantly different from that by Frank et al.(1985).When v is high enough,the spectrum of the accretion disc can be considered as a single temperature accretion disc.It is good for us to take Fv∝v4.5 to be the characteristic spectrum of the accretion disc.
