摘　　要：文章给出在两个SDSS类星体能谱中证认出的重金属吸收系统.对每一个吸收系统,作者探测到10个明显的重金属吸收线.这两个吸收体的红移明显小于相应类星体的红移(zabs≤ze).因此,这两个重金属吸收系统极可能与在相应类星体的视线方向上的插入星系有关.Abstract： It shows two confirmed heavy metal absorption systems detected on the spectra of two SDSS quasars. For each absorption system, 10 significant heavy metal absorption lines are detected. The redshifts of the two absorbers are much less than that of the corresponding quasars （Zaba〈〈ze ） , suggesting that the former might be far away from the latter. The two heavy metal absorption systems are likely to be associated with the intervening galaxies lying on the line of sight of the corresponding quasars.
