中文摘要：贝叶经,尤其是西藏博物馆收藏的梵文贝叶经,是国内外社会科学和南亚文化圈中具有很高学术价值和最具开发潜力的古文献典籍。它对了解和研究中印文化的交流史与印度梵语文化对我国中原文化和藏族传统文化的影响,都有着重要的社会历史意义和学术意义。观察发现经叶上的文字被一层白色物质覆盖,许多字迹显得模糊难辩,是否出现了霉菌侵蚀和污染?为了更好地保护这些珍贵的文化遗产,利用三维视频显微镜和傅里叶变换红外光谱仪,对"白色粉状物"进行分析。分析结果表明,这种白色粉状物应是贝叶经加工时,为防止贝叶之间粘连而人为添加的高岭土,这种情况也为"薄伽梵歌及注释"经和0738号贝叶经上的现象所印证,即所用粉末物经检测为白色瓷土粉。通过这次取样分析,可为今后的贝叶经保护提供科学依据。

英文摘要：Bayesian classics,especially the collection of Sanskrit Bayeux manuscripts in the Tibet Museum,have high academic value and potential for international social science and South Asian cultural research.They are important historical,cultural and academic materials for the study of Sino-Indian cultural exchanges between the Indian Sanskrit culture and Chinese cultures,and the Indian Sanskrit culture's impact on traditional Tibetan and Chinese mainland culture.A layer of white power was found to cover the Bayeux's script,which obscured the characters.Is it mildew or contamination?To better protect this precious cultural heritage,three-dimensional video microscopy and Fourier transform infrared spectrometer were used to analyze the"white powder"appearring in the Bayeux manuscript. Results show that the white powder is kaolin,which was added during the manufacturing process to prevent pages from sticking to each other.The same results were found on"Bhagavad Gita and its notation"and on Bayeux classic No.0738.The white power was found to be porcelain clay powder.The research provides scientific results for conservation of Bayeux classic manuscripts.
