The fabrication of the calibration source is a critical part for the non-destructive and quantitative investigation of blue and white porcelains using EDXRF. In order to minimize the effects on the results due to the matrix difference between the samples and the calibration source, broken porcelain pieces of the Ming and Qing dynasties with matrix conditions similar to those of the measured samples are used directly as calibration sources. The 13 trace elements, viz. Ti, Mn, Fe, Co, Ni, Cu, Zn, Ga, Pb, Rb, Sr, Y, and Zr, have been quantitatively measured for 20 imperial blue and white porcelains of the Qing dynasty and for 11 contemporary Jingdezhen porcelains. The data are then analyzed by the principal component analysis method. The clustering of the data and the identification of the porcelains are then investigated.
对于使用 EDXRF 进行无损和定量研究青花瓷，校准源的制作是一个关键环节。为了最大限度地减少由于样品和校准源之间的基体差异对结果的影响，直接使用与被测样品基体条件相似的明清碎瓷片作为校准源。对 20 件清代御窑青花瓷和 11 件当代景德镇瓷器进行了 13 种微量元素 Ti、Mn、Fe、Co、Ni、Cu、Zn、Ga、Pb、Rb、Sr、Y 和 Zr 的定量测量。然后，使用主成分分析方法对数据进行分析。接着对数据的聚类和瓷器的鉴别进行了研究。
