摘　　要：利用金相显微镜、电子扫描显微镜、能谱仪和多接收等离子体质谱仪对凤翔出土的青铜建筑构件以及相关文物进行了研究，发现：凤翔出土铜建筑构件含铜量在73％～83％之间，含锡量在10％-18％之间，含铅量在1％～10％，为铅锡铜三元合金；铜建筑构件的铅同位素关系图显示其与礼县几乎完全重合，涵盖了宝鸡县青铜器铅同位素比值分布范围，说明凤翔青铜构件系由秦人自己制作。Employing the instruments including metalloscope, electron scanning microscope, Energy Disperse Spectroscopy, and muhi-acceptive ICP-MS , the paper studies the bronze architectural components and relevant cultural relics excavated in Fengxiang area, it comes to the conclusion that the bronze architectural components excavated in Fengxiang contains the proportion of copper between 73 and 83 percent, the proportion of tin between 10 and 18 percent, the proportion of lead between 1 and 10 percent, they are alloys of lead, tin and copper. The lead isotope diagrams of the bronze architectural components show that they are almost identical with that of the Lixian county. The distribution range of lead isotope ratio of Baoji county is contained within this, it shows that the bronze architectural components of Fengxiang were made by the Qin people in Qin Dynasty on their own.
