To establish an XRD method for evaluating the quality of Os Draconis and Dens Draconis and applying in judgement of the counterfeit.
Dens Draconis, Os Draconis and the counterfeit of Os Draconis were analyzed by XRD. Their diffraction patterns were clustered analysis and evaluated their similarity degree.
Established the analytical method of Dens Draconis and Os Draconis basing the features fingerprint information of the 10 common peaks by XRD pattern. Obtained the XRD pattern of the counterfeit of Os Draconis. The similarity degree of separate sources of Dens Draconis was high,while the similarity degree of separate sources of Os Draconis was significant different from each other.
This method can be used for identification and evaluation of Os Draconis and Dens Draconis. It also can be used for identification the counterfeit of Os Draconis effectively.
建立一种X射线衍射（XRD）方法用于评估龙骨和龙齿的质量，并应用于伪品的鉴别。
采用XRD对龙齿、龙骨及龙骨伪品进行分析，对其衍射图谱进行聚类分析并评价相似度。
基于XRD图谱中10个共有峰的特征指纹信息建立了龙齿和龙骨的分析方法，获得了龙骨伪品的XRD图谱。不同来源龙齿的相似度较高，而不同来源龙骨的相似度差异显著。
该方法可用于龙骨和龙齿的鉴别与质量评价，也能有效鉴别龙骨伪品。
