项目摘要

Good environment has been expected to conserve the cultural properties, for example, metallic crafts, wood image, paintings, cloth, and the others. Such good environment interrupts the corrosion and /or degradation of cultural proper-ties. Until now, humidity, poisonous gas, and other hazards have been measured to evaluate the environment. However, the evaluation method, from the side of cultural property which is corroded, does not exist. The object of this investigation is to develope the new evaluation technique of environment from the side of cultural property materials. At the same time, it is the object to investigate the surface reactions of cultural materials. The obtained results are as follows.(1)By using the metallic thin films, for example, Ag, Cu, Fe,Co, and these alloys, sputtered onto the glass substrate, are used to evaluate corrosion environment. After the thin films were exposed in various circumstance, the reflectane from the metal thin film surface is measured by spectro photometer. For example, the reflectance of Ag thin film decreases linearly with increasing time. This is due to surface corrosion of metal film. The slope changes by the quality of environment. Therefore, good or bad of environment can be determined by measuring the reflectance. By this new technique, the effects of season, wind speed, weather, et al. have been clarified.(2)Small size, light weight and low cost apparatus to measure the reflectance is developed, It is confirmed that the efficiency is high as a result of measurement.(3)Surface reactions of the cultural property materials have been investigated and some of corrosion mechanisms are clarified.

金属工艺品、木刻、绘画、布料等文化遗产的保护需要良好的环境。这种良好的环境阻止了文化财产的腐蚀和/或退化。到目前为止，湿度，有毒气体和其他危害已经被测量来评估环境。然而，从文化财产的角度来看，这种评估方法并不存在。本研究的目的是从文物材料的角度发展新的环境评估技术。同时，它也是研究文化材料表面反应的对象。所得结果如下。(1)By使用溅射到玻璃衬底上的金属薄膜，例如Ag、Cu、Fe、Co和这些合金，来评估腐蚀环境。在各种环境下曝光后，用分光光度计测量金属薄膜表面的反射率。例如，Ag薄膜的反射率随时间的增加而线性下降。这是由于金属膜的表面腐蚀。坡度随环境质量的变化而变化。因此，环境的好坏可以通过测量反射率来确定。通过这项新技术，澄清了季节、风速、天气等因素的影响。（2）研制了一种体积小、重量轻、成本低的反射率测量装置，测量结果表明该装置效率高。（3）对文物材料的表面反应进行了研究，并对一些腐蚀机理进行了探讨。
