【摘要】 采用粉末X射线衍射(XRD)技术对矿物药磁石进行分析,测定其XRD Fourier指纹图谱,并作模糊聚类法分析和相似度评价。初步建立了以11个共有峰为特征指纹信息的12批磁石的XRD Fourier指纹图谱分析方法:所分析样品XRD Fourier指纹图谱的相似度为0.849～0.998;少数样品XRDFourier图谱的峰数目和峰强有一定差异;生品与煅制品的XRD Fourier图谱有明显差异。XRD Fourier指纹谱分析法可用于磁石药材的鉴定与分析。更多还原

【Abstract】 The technology of powder X-ray diffraction(XRD) was used for analysis magnetitum and the XRD Fourier fingerprints were determined.The dates were analyzed by fuzzy cluster and fingerprint similarity evaluation software to compare the similarity of samples.XRD fingerprint with 11 common peaks of 12 batches of magnetitum were established preliminarily.The coefficients were from 0.849 to 0.998.There are a small number samples differed from others.There are obvious differences in the between the pre-and post-processing samples.This paper shows the powder XRD Fourier fingerprint could be used for the appraisal and the study of the magnetitum.更多还原
