The technology of powder X-ray diffraction (XRD) was used for analysis Chloriti Lapis and the XRD Fourier fingerprints were established. The dates were analyzed by fuzzy cluster and fingerprint similarity evaluation software to compare the similarity of samples. XRD fingerprint with 10 common peaks of 14 batches of Chloriti Lapis were established. The average, median coefficients of crystal lattice spacing d (A), peak position 2 theta, relative intensity value I/I0 (%) were all more than 0.95. And similarity( angle cosine value) were all more than 0. 97. There were small number samples differed from others. And obvious differences between the pre-and post-processing samples. This paper shows the powder XRD Fourier fingerprint can be used for appraisal and study of the Chloriti Lapis.
采用粉末X射线衍射（XRD）技术对青礞石进行分析，建立了XRD傅里叶指纹图谱。运用模糊聚类和指纹相似度评价软件对数据进行分析，以比较样品的相似度。建立了14批次青礞石具有10个共有峰的XRD指纹图谱。晶格间距d（Å）、峰位2θ、相对强度值I/I0（%）的均值、中位数系数均大于0.95，相似度（夹角余弦值）均大于0.97。少数样品与其他样品存在差异，处理前后的样品之间存在明显差异。本文表明粉末XRD傅里叶指纹图谱可用于青礞石的鉴定和研究。
