【摘要】 为了解云冈石窟大气中粉尘污染的现状,用X射线衍射、扫描电镜(EDAX)和显微镜对大气中粉尘的主要物质成分进行了分析。选择SO2和粉尘两个标志作为变动因素,通过室内模拟试验就粉尘对石雕的影响进行了探讨。结果表明,粉尘对石雕的影响既有物理作用,又有化学作用,物理风化和化学风化长期存在,交替作用,互相促进,致使云冈石窟石雕遭受严重的风化。更多还原

【Abstract】 To know the current status of airborne pollution in Yungang Grottoes, main substantial composition of the deposition of airborne particles is analyzed by means of XRD, SEM( EDAX) , and microscope. Then S02 and the deposited air borne particles were chosen as the variable parameters to make simulation test. The results show that airborne pollutants have both physical and chemical influences on the rock statues so as to make the statue decaying very seriously.更多还原
