摘　　要：利用同步辐射硬X射线荧光微束技术,对模拟实验获得的熔融黄铜、固态还原反应生成的黄铜和姜寨黄铜片(中国最早的人工冶炼金属)进行微区扫描测定,获取了锌、铅元素的面分布信息。结果表明:姜寨黄铜片的铅、锌分布规律与固态还原反应生成的黄铜类似,而与熔融黄铜明显不同,据此推断姜寨黄铜片为铜、锌矿经固态还原工艺获得。这一分析结果支持了中国冶金本土起源的观点。Brass through melting process and bulk brass by solid-state reduction were obtained in simulation experiments. These two kinds of synthetic brass and the ancient brass unearthed in Jiangzhai site,Shaanxi Province（ the earliest artificial alloy in China） were analyzed with synchrotron radiation μ- X-ray fluorescence techniques. The results showed that the distribution of zinc and lead in the ancient brass sheet was similar to that of the bulk brass by solid-state reaction,but it was obviously different from that of the brass made by melting process. So it could be inferred that brass sheet unearthed in Jiangzhai site was made by solid-state reaction. This result supports the indigenous origin of metallurgy in China.
