摘　　要：本文利用共聚焦显微拉曼光谱(CRS)结合扫描电镜-X射线能谱(SEM-EDS)技术对唐代一铜佛像的表面成分、形态及元素组成进行了分析。结果显示,该铜佛像主要是由Cu-Pb-Sn三元青铜合金组成,表面腐蚀物主要是由氧化铜,氧化亚铜,碱式碳酸铜,氧化铅,氧化锡,碳酸铅和氯化铅组成,这些成分在空气中都比较稳定,不会再对铜佛像造成进一步破坏。Scientific analysis of metal artifacts is an important basis for the origin and development of ancient metallurgy,which can provide important information for protection and restoration of cultural relics.In this paper,a Tang Dynasty Buddha was studied by the confocal microscopic raman spectra（CRS） and scanning electron microscopy coupled to energy dispersive spectroscopy（SEM-EDS）.The results show that the Tang Dynasty Buddha was composed by Cu-Pb-Sn bronze alloy,and the surface corrosions were assembled by cupric oxide,cuprous oxide,basic copper carbonate,massicot,jewellers putty,lead carbonate and lead chloride.These corrosions were stable in the air and would not further damage the Buddha.
