用4129.7A Eu Ⅱ谱线测定了银盘74颗F和G矮星的铕丰度。这些恒星是从Edvardsson等人（1993）的样本中选出的，与Woolf等人（1995）的发现相比，[Eu/Fe]显示出更小的散射和与[Fe/H]的趋势稍弱。将两种分析的数据均质化并合并。并对所采用的有效温标进行了讨论。
Europium abundances for 74 F and G dwarf stars of the galactic disk have been determined from the 4129.7 A Eu II line. The stars were selected from the sample of Edvardsson et al. (1993) and [Eu/Fe] shows a smaller scatter and a slightly weaker trend with [Fe/H] than found by Woolf et al. (1995). The data of the two analyses are homogenized and merged. We also discuss the adopted effective temperature scale.
