摘　　要：采用X射线荧光仪、金相显微镜和扫描电镜等现代检测手段,分析金沙遗址出土铜片的元素成分和金相组织,探讨其加工工艺。结果表明,铜片为高温热锻成形,其热锻温度范围在500-700℃之间,符合现代金属学原理。铜片表面的树形纹饰是用预先制作的树模在铜片上压印而成。这一研究结果对进一步了解成都平原的青铜加工技术有重要意义。The component analysis and metallographic observation on the copper sheet unearthed from Jinsha site situated in the suburb of Chengdou city are conducted by X-ray fluorescence spectrometry （XRF）, metallographie microscopy and scaning electron microscopy （SEM）, respectively. And the processing technology is discussed. The results reveal that the copper sheets are manufactured by using the technology of hot-forging, and temperature range of hot-forging is 500-700℃. The working process is consonant with the modern metallurgical principle. Tree-shape decoration on the surface of the copper sheet is impressed using the tree-shape mould. This researching achievement is significant to probing into bronze processing technology in ancient Chengdu flatlands.
