中文摘要：

为了研究西安钟楼建筑彩画的制作材料,本工作采用超景深显微镜、X射线荧光分析仪、X射线衍射仪和气相色谱质谱联用仪对西安钟楼建筑彩画样品进行了分析。结果表明,该彩画样品地仗层采用单披灰制作工艺,两层红色颜料都是土红,绿色颜料使用了近代人工合成颜料——巴黎绿,胶粘剂含有动物胶。该研究成果对西安钟楼彩画后期修复保护材料和工艺的选择具有指导意义。

英文摘要：

Ultra-depth field microscopy,X-ray fluorescence,X-ray diffraction,and gas chromatography-mass spectrometry were used to analyze the materials used to make the colored drawings in the Bell Tower in Xi＇an. These studies show that the technique of＂only plaster layer＂is the colored drawing＇s background plaster. Red pigments were hematite and the green pigment was an artificial pigment（ emerald green）; the binding medium was composed mainly of animal glue. This research is of significance for restoration and conservation of colored paintings of the Bell Tower in Xi＇an.
