石质文物的保管石质文物主要包括生产工具、雕像、石碑、石窟、建筑构件、小型艺术品等。这类物品的耐久性主要看器物的质地,也就是和所用石材的质量和存放地点有关。有的石质文物存放在露天,长时期经受风吹雨淋,加上生物的侵蚀等多种因素的危害,导致其内部结构发生不同程度的变化。有的石质文物风化剥蚀严重,有的甚至发生酥碱粉化乃至则断裂残破。另外,空气中的有害气体的腐蚀,温度和湿度的剧烈变化所引起的热胀和冷 Stony cultural relics preservation Stone relics mainly include production tools, statues, steles, grottoes, building components, small works of art and so on. Durability of such items mainly depends on the texture of the artifacts, that is, the quality of the stone used and the location of the deposit. Some stone artifacts stored in the open air, prolonged exposure to wind and rain, coupled with biological erosion and other hazards, resulting in varying degrees of internal structure changes. Some of the stone artifacts weathering and denudation serious, and some even occurred crushing flour crushing rupture. In addition, the harmful gases in the air corrosion, temperature and humidity caused by the dramatic changes in the thermal expansion and cold
