拉曼光谱、植硅体和淀粉粒分析在纸质文物研究中的应用

通过对一张纸质人物画像的拉曼光谱、植硅体和淀粉粒分析，认为：①在某些情况下，特殊颜料的拉曼分析结果有助于文物断代。（参植硅体分析可提供造纸原料的特定植物学信息（如科类、种属等），因此，在古代手工纸原料的鉴别方面有一定的应用潜力。③淀粉粒分析与碘-碘化钾显色反应相结合，或可明确纸张中是否施胶以及施胶剂母源植物的种类。

The Application of Raman Spectroscopy,Phytolith and Starch Analyses to Research of Paper-based Materials

A combined use of Raman spectroscopy, phytoliths and starch grain analyses was employed to an age-unknown Chinese portrait. The obtained results are listed as follows： （1） for some cases pigment identification by Raman spectroscopy is of special use to the dating of artifacts; （2）Since phytoliths analysis can provide sometimes certain information about the plant taxonomy background, it may be of the potential to work as a new method to distinguish and determine the plant materials used in ancient Chinese papermaking; （3）a combination of starch analysis and staining methods （as Iodine-Kl reagent） may uncover not only whether the glutinous substances were used, but also what exactly they, if any, were and where they were from.
