本文运用双轴应力测试仪测定了单纯画布和带颜料层画布在同样环境温度、湿度变化下所产生的应力变化、这项测试为研究画布和颜料层之间的相互作用提供了第一手资料。通过比较实验发现，油画的开裂和老化主要由颜料层引起的，实验还证明：微小温度变化对油画应力变化具有显著影响以及环境相对湿度pH＞90％将严重威胁油画的保存。
This paper uses the biaxial stress tester to measure the change of stress caused by the changes of the canvas and the paint with the same environmental temperature and humidity. This test provides the first-hand information for the study of the interaction between the canvas and the paint layer . Through comparative experiments, it is found that cracking and aging of oil paintings are mainly caused by pigment layers. Experiments also show that slight temperature changes have significant influence on oil stress changes and environmental relative humidity (pH> 90%) will seriously threaten the preservation of oil paintings.
