This paper studied the chemical characteristics of rice paper, pigments and seals on Chinese calligraphies and traditional Chinese paintings. The techniques used here were Fourier transform infrared (FT-IR) spectroscopy and X-ray diffraction (XRD). FT-IR allows good identification of the substances present in pigments and inkpads and differentiates each era of rice paper. This can be the base of estimating the age of rice paper. Different crystalline phases can be identified by XRD, which is further evidence to separate different kinds of pigments or inkpads. Both of these methods were non-destructive in situ analysis and can be used in the identification in calligraphies and traditional Chinese paintings. These results confirmed that the applied techniques are relatively quicker and more reliable than traditional approaches authenticated by years of experience.
本文研究了宣纸、中国书画颜料和印章的化学特性。这里使用的技术是傅里叶变换红外（FT-IR）光谱和X射线衍射（XRD）。傅里叶变换红外光谱能够很好地识别颜料和印泥中存在的物质，并区分宣纸的各个年代。这可以作为估计宣纸年代的依据。X射线衍射可以识别不同的晶相，这是区分不同种类颜料或印泥的进一步证据。这两种方法都是无损原位分析，可用于书画鉴定。这些结果证实，与多年经验验证的传统方法相比，所应用的技术相对更快、更可靠。
