影响文物保存的环境因素

The conservation and environmental effect

影响文物保存环境因素作文献综述。内容分三部分：温湿度、光、污染气体（包括硫氧化物、臭氧、颗粒物质等等），各项因素对不同质地的文物影响程度不相同。各项因素之间产生的协同作用，其对文物的损伤后果更为严重。

The article reviews the damage of cultural relics caused by environmental factors. In the conservative environment, the three parts must be considered. They are humidity and temperture, light and gaseus pollutants (including sulfur oxides, nitrogen oxides, oxides, ozone, formaldehyde, particulates etc.) There are three different modes of deterioration (physical change, chemical leaction, bileeterioration) that are influenced byhumidity. All oganic materials(paper, texitile, colorants etc) are at risk under light. The various gaseous pollutants become a worid - wide hazerd to the antiquities. The degree of deterioraion of various classes of material are different with response of individual environmental factors .The synergism of factors may be more dangerous to the deterioration of materials.
