摘　　要：利用微区拉曼光谱与扫描电镜配置的电子探针等技术,分析了两块陶器样品的陶衣。拉曼光谱的分析结果表明,黑色陶衣的主要显色物质为炭黑,红色陶衣的显色物质为赤铁矿。电子探针线扫描分析的结果表明,红色陶衣中铁的含量明显高于内部坯体。陶器样品剖面的微区拉曼光谱分析可有效地避免样品表面其他掺杂原子的影响。Two different ancient pottery coatings have been analyzed by micmzone-Raman spectrum and SEM- EDS（scanning electronic microscopy- energy dispersive spectrum）. The results of the Raman spectrum indicated that the carbon black was the main color constituent of black coating and the hematite was that of red coating. The results of linear SEM - EDS indicated that the content of iron in the red pottery coating was remarkably higher than that in the inner adobe of pottery. The results also showed that the effect of other impurity atom could be avoided by analyzing the cross section of the sample with micmzone-Raman spectrum.
