摘　　要：李家坝遗址是中国西南地区一处重要的巴人遗址,出土了大批精美的文物,其中一批西汉时期鎏金青铜器的发现,为人们了解巴蜀地区青铜鎏金技术提供了宝贵实物资料。鎏金工艺是中国古代传统工艺中的一只奇葩,最早出现春秋时期,流行于战国和两汉时期。李家坝墓地出土的汉代鎏金青铜器,通过扫描电镜分析脱落碎片,结果显示:鎏金层中存在大量条状突起物为没有完全溶于Hg的金丝,表明人们采用"细剪金箔"的方法制备原料;同时,均匀分布的Ag说明当时人们在制作金汞齐时添加了Ag。Lijiaba site in southwest China was a very important Ba ruins.A large number of cultural relics were unearthed recently.Some gilt bronzes had been found in Western Han Dynasty tombs.They provided original samples for a further study on the technique of gilt bronze in Ba-Shu area.As we know that gilt process,which first appeared in the Spring and Autumn Period and was popular in the Warring States period and Han Dynasty,was a wonderful work of traditional craft in ancient China.The investigation on the falling debris from gilt bronze by scanning electron microscopy showed that lots of protruding objects in strips gilded layer were spun gold which didn＇t completely melt in Hg and indicated that there was a ＂fine-cut gold foil＂approach to the preparation of raw materials.Meanwhile,the uniform distribution of Ag makes clear that Ag was added when they product the gold amalgamation.
