通过测量模拟壁画块的重量，研究了大气湿度和温度对敦煌莫高窟壁画的影响。在开放条件下，大气湿度和温度的每日变化对这些壁画的含水量有明显的影响。大气与壁画之间存在着明显的水分交换，即两者之间存在着±43 g m−2的吸湿-解吸“呼吸”过程。 来自树木带的蒸散，降水和极端干燥的天气也会对壁画的湿度产生影响。如果洞穴被关闭，一项类似的研究发现，关闭可以使温度和湿度变化的影响消失。在这种情况下，壁画含水量保持稳定，水盐变质的危害大大降低。在封闭的条件下，人工冷凝和控制洞穴的温度和湿度，非常有效地稳定了壁画中的水分活动。这清楚地表明了保护洞穴文物所需的未来步骤。
The aim of this paper is to study the influence of atmospheric humidity and temperature on the mural paintings in the Mogao Grottoes of Dunhuang by measuring the weight of a simulated mural block. Under open conditions, the daily changes in the atmospheric humidity and temperature have an apparent effect on the water content of these murals. There exists an obvious water exchange between atmosphere and mural, that is, there is a ±43 g m−2 moisture absorption–desorption ‘breathing’ process between the two. Evapotranspiration from the tree-belt, precipitation, and extremely dry weather also have an effect on the moisture associated with a mural painting. If the cave is closed, a comparable study finds that closure can make the effects of temperature and humidity changes disappear. The mural water content in this case remains stable and the harm due to water-salt deterioration is greatly reduced. Under closed conditions, artificial condensation dehumidification and control of the cave's temperature and humidity stabilizes water activity in the mural paintings very effectively. This is a clear indication of the future steps required to protect the cave's cultural relics.
