摘要
建立了一种对未知产品信息的塑钢窗样本的快速分类方法。利用X射线荧光光谱法(XRF),采用手持式荧光光谱仪,以Ag作阳极靶、电压为50 kV、电流为200μA、采集时间为70 s,对40个不同产地、不同品牌、不同用途的塑钢窗进行元素分析。依据实验结果筛选出具有种属差异性的指标元素Pb、Ti、Cl,同时依据“含量标准偏差和”,综合考虑“品牌、产地、用途”之间的相对显著性关系,实现对塑钢窗样本的分类。结果表明,该方法可对样本进行完全分类,为现场勘查所采集的检材分类提供了新模式,具有一定的实战意义。
A fast clustering method was established for plastic steel window samples with unknown product information under the three indicators including product source,brand,and use purpose.The element contents of 40 plastic steel win-dow samples with different brands,different use purposes and different sources were analyzed by X-ray fluorescence spec-trometry and a handheld fluorescence spectrometer under the experimental conditions of Ag as anode target,voltage of 50 kV,current of 200μA and acquisition time of 70 s.According to the experimental results,the index elements of Pb,Ti,Cl with species difference were selected.Through calculating the sum of standard deviation of the samples and con-sidering the relative significant relationship among the brand,source and use purpose,the clustering results of 40 samples of plastic steel windows were obtained.This method can provide a new model for the clustering of samples collected in field investigation,indicating a certain practical significance.
