摘要
利用色度仪、反射密度计和显微分析技术,对汉代陶俑彩绘颜料进行了综合研究。测定了各种颜料层的色度、密度和颜料表相的显微结构信息,获得各种颜料的色度分布范围,表征出彩绘颜料层的密度和风化状况,关联分析了颜料密度与颜料特征之间的关系,构建了球体色度容差评估模型,为颜料层表面的色泽评价提供定量化评价,为陶俑彩绘颜料保存时间尺度的评估提供分析数据,为陶俑彩绘的科学保护提供科学依据。
The pigments of the Han Terra-cotta figures were comprehensive researched by chroma meter, reflection densitometer and microanalysis technique. By measuring chromaticity, density and surface mierostructure information of various pigments, this thesis characterized relative density and weathering conditions, analyzed the relation between pigment density and pigment characteristic, construct the sphere tolerance model. The work offers the quantitative evaluation system for color evaluation of pigments, the scientific analysis data for evaluation of pigments conservative time scale, and the scientfic basis for scientific protection of painted pottery figurines.
