摘要
选择了土红、孔雀石绿、白铅矿和铅丹４ 种在古代彩绘中有代表性的颜料，通过改变环境湿度有无紫外光照射，考察了它们的变化情况。实验结果表明：土红、孔雀石绿比较稳定，光照射和湿度对其影响甚小；铅颜料容易变化，尤其是铅丹在光照高湿（相对湿度６６％ ～８１％ ）条件下变成铅白。经综合分析，确定出保存带有精美彩绘的秦陵铜车马的最佳湿度为４４％ 左右。
Four typical pigments,hematite,malachite,red lead and cerussite have been studied by changing environmental humidity and illuminating with or without ultraviolet ray.It is found that hematite and malachite are more stable to both light and moisture than lead pigments,especially red lead,which can change into white lead at high humidity( RH from 66% to 81%)with ultraviolet ray.Relative humidity of 44% is selected as the best one for preserving bronze chariot and horses decorated with colored drawings.
