摘　　要：为了建立汉代彩绘工艺、彩绘颜料等方面的数据库,为跨地域横向对比研究及彩俑的中长期保护和博物馆展出提供科学依据,本研究利用MINLTA CR-300色度仪、X-Rite Spectrodensitometer密度仪、XTL系列显微镜分析方法,对汉代陶俑彩绘6种颜料层61个样品的色度数据和5件陶俑残片颜料密度值的分布范围和表面显微结构信息特征进行了系统的分析测试。在大量色度数据的收集分析基础上,构建球体色度容差评估模型。球体色度容差评估结果表明,黑色样品保存较为完好,橙红色色度腐蚀现象严重,橙红色陶俑样品较其他样品分布均匀。颜料密度分析表明,橙红色陶俑腿残片保存状况相对较好,表面的颜料层较均匀且致密。显微分析发现,5%B72乙醇体系对表面颜料加固中,B72加固剂的分散性好,颜料表面无明显变化,在陶俑彩绘颜料保护过程中,B72-乙醇体系是可以选择的。The purpose of this research is to build a database of pigments and technique of Han Dynasty painting to gain scientific evidence of comparative study of paintings from different regions, to protect painted pottery figurines for middle to long term, and for the exhibition of these objects in the museum. MINLTA CR - 300 Colorimeter, X - Rite spectrodensitometer densitometer and XTL series microscope were used to analyze the chromaticity of 61 samples from 6 pigment layers and the density and surface microstructure information of 5 pigments from painted pottery fragments. Based on a large number of data and analysis, a sphere chroma tolerance evaluation model was construct. The model suggests the black samples are preserved well, while the orange samples are badly worn. But the pigments distribution of the orange samples is more evenly than others. Pigment density analysis shows that orange pigments on a fragmented pottery figurine＇s leg are preserved relatively well with uniform and compact pigment layer on the top. Microanalysis shows that 5% B72 ethanol system is good for surface pigment reinforcement,which has good dispersion with no significant change of the pigment surface. 5% B72 ethanol system is an option for the protection of painted pottery figurine.
