【摘要】 对矮新星ＡＢＤｒａ的最小二乘拟合表明，黑体吸积盘模型预言的连续谱能粗略地拟合该星在爆发期间的ＩＵＥ观测，较小的偏差可以归因于光学薄气体的复合辐射或／和热斑的黑体辐射。拟合给出了一组吸积盘参量的合理值。更多还原

【Abstract】 In this paper the least-squares fit for dwarf nova AB Dra shows that the continuum predicted by the blackbody accretion disk model can roughly fit to the observed IVE data and the smaller deviation may be attributed to an appropriate amount of recombination radiation from optically thin gas or/and black body radiation from the hot spot.From the fitting we have obtained the reasonable values of some parameters of the disk and the system which it belongs to.更多还原
