摘　　要：通过调查发现望都汉墓壁画表面有大量的盐分结晶,主要为硫酸镁、硫酸钙和氯化钠等。经分析认为,壁画表面的氯化钠主要来源于墓室重修后的大门,硫酸镁和硫酸钙则来自壁画的支撑体烧结砖;地下水和墓室封土中的少量离子亦是壁画盐分的另一处来源地。外部环境的变化通过墓室的半封闭门与墓室内微环境发生交换,导致墓室内高湿度波动,是壁画产生盐害的诱发因素。Through a survey this research finds that there are abundant crystalized salts on the surface of the murals in the Han-Dynasty tombs at Wangdu.They are mainly magnesium sulfate,calcium sulfate,sodium chloride,and so forth.The analytical results show that the sodium chloride on the surface of the murals mainly comes from the restored gate of the tomb chamber,whilst the magnesium sulfate and calcium sulfate come from the burned bricks that were built to support the murals.Groundwater and some ions from the above-ground mound earth are other sources of the salt.External environmental change interacts with the micro-environment inside the tomb chamber through the half-closing gate of the tomb,which leads to high moisture changes in the chamber and is one of the triggers of the occurrence of the salt on the murals.
