摘要:藏纸是一种民族特色手工纸，被广泛应用于经书典籍、政府公文、档案卷宗等的书写，同时还被用于经书、档案的修补。为科学证实藏纸的良好性能，编写藏纸合理说明书，对其耐久性进行了研究。选取直孔藏纸、东巴纸、宣纸和手工构皮纸为研究对象，采取干热加速老化方法处理样品，分别测定其老化前后白度、耐折度、抗张力等指标，并进行红外光谱分析。结果表明，直孔藏纸老化前各项指标并不突出，但老化前后其白度、耐折度、抗张力保留率较好，且老化前后红外光谱分析变化并不大。老化前后直孔藏纸白度、耐折度、抗张力保留率分别为95.22%、74.65%、79.71%，均大于本实验所选其他手工纸，说明直孔藏纸具有良好的耐久性。

Abstract:Tibetan paper is a kind of ethnic handmade paper choosed, which is widely used in the writing of classics, government documents, file files, etc., and is also used for the repair of scriptures and archives. In order to scientifically confirm the good performance of Tibetan paper, a reasonable specification for Tibetan paper was prepared and its durability was studied. We chose 4 kinds of paper （Zhikong Tibetan paper, Dongba paper, Xuan paper and Mulberry Paper） to compare their properties （such as whiteness, folding endurance, tension stress） before and after accelerating aging. The study showed that the variation of the properties of Zhikong Tibetan paper was not obvious. Before and after accelerating aging, the durability of the whiteness, folding endurance and tension stress of the Zhikong Tibetan paper were 95.22%, 74.65%, 79.71%, respectively. These data were superior to other handmade papers, which fully demonstrated that Zhikong Tibetan paper had good durability．
