在明亮的太阳恒星天狼星的光谱中，共546条谱线（包括26个元素）的等效宽度为380 ~ 930 nm。高分辨率、高信噪比的光谱是用北京天文台（中国兴隆）2.16米望远镜上的库德勒梯队光谱仪获得的。在这里，我们还给出了我们的测量结果与Strom等人和Sadakane & Ueta的测量结果之间的等效宽度比较。
The equivalent widths of total 546 lines (26 elements are included) in the spectrum of the bright Am star Sirius from 380 to 930 nm are tabulated. The high-resolution, high signal-to-noise ratio spectrum was obtained with the Coudé Echelle Spectrograph attached to the 2.16 m telescope at Beijing Astronomical Observatory (Xinglong, China). Here we also give the results of the equivalent widths comparison between our measurements and those of Strom et al. and Sadakane & Ueta.
