微环境下醋酸纤维素酯胶片的保存

本文讨论了为最大程度避免醋酸片基降解，并对已降解变酸的胶片进行处理，目前国内外使用的几种在微环境中测量胶片酸度及吸收胶片散发出的酸性气体，以控制胶片保存环境，延长胶片寿命的方法，并着重介绍我们自己研制的两种成果“气敏性影像载体衰变监测试纸”及“复合除酸防酸材料”在微环境中所起的作用。

Preservation of Cellulose Acetate Film in Enclosed Environment

This article presents a discussion on the methods for redacing the degradation of TAC film to the minimum and remedying film already degraded and become acid.Several means used worldwide for determining the film acidity and absorbing the acid vapour released by the film to control the storage environment and extend the film life are also introduced,together with two research achievements accmplished by the authors: apoursensitive imagesupport degradation testing paper and complex antiacid preservation material
