酸沉降对室外文物材质破坏的试验方法

The experimentation for the effect of acid deposition on outdoor cultural relics and ancient structures

用现场暴露试验和室内模拟试验检验酸沉降对文物材料的破坏程度。提出了两种试验方法、试验步骤、试验后材料腐蚀速率的计算，建立材料损伤函数的几个步骤。

Both outdoor test and indoor simulated experiment are conducted to have measured the erosion - damage of acid deposition to the different materials of cultural relics. Two test methods are suggested, steps of test, the erosion - speed guage of material in wake of test- Several steps of damage function setting.
