金沙遗址出土金属器的实验样品全部选自金沙遗址Ⅰ区“梅苑”地点2001年机械施工时挖出的器物。根据部分出土金器、铜器的实际情况 ,或进行沃损检测 ,明确其表面合金成分 ;或显微镜下观察纹饰的工艺痕迹 ,推断其形成方法 ;或取样进行金相检验和成分分析 ,确定其合金化学成分和加工工艺。
Jinsha site unearthed metal experiment samples are all selected from the Jinsha site Ⅰ “Meiyuan” site 2001 mechanical construction dug artifacts. According to the partial unearthed gold and copper, the actual situation, or the detection of loss of damage, clear the surface alloy composition; or microscopy microscopy traces of process marks, to infer its formation method; Or sample metallographic examination and composition analysis to determine its Alloy chemical composition and processing technology.
