Abundances of HR 4487, 14 Hyd and 3 Cen A

Ussing CASLEO echelle spectrograms, elemental abundances are derived for the sharp-lined non-magnetic CP stars HR 4487, 14 Hya and 3 Cen A. The first two stars are members of...本研究借助CASLEO中阶梯光栅摄谱仪的光谱数据，对三颗窄谱线非磁场化学特殊星(CP star, Chemically Peculiar star)——HR 4487、长蛇座14星（14 Hya）以及半人马座A星（3 Cen A）——的元素丰度进行了推导。其中前两颗恒星为……的成员。
