摘要
本文将Lachance-traill(L-T) 方程理论α系数法应用于古青铜钱币中的Pb、Cu、Sn 分析, 并与基本参数法和模拟标样法的结果进行了比较。由于本法和模拟标样法都是从基本参数法演变来的, 使用的标样是一样的, 三种方法计算结果数据比较接近。本法计算速度快、效率高, 但对标样的依赖性较大。
In this paper,the theoretical alpha coefficients of L T equation were applied to the analysis of Pb,Cu and Sn in ancient bronze coins by X ray fluorescence spectrometry.The results obtained in this way are in agreement with those by the fundamental parameter method and the simulant standard samples method,because this method and the simulant standard samples method were both developed from the fundamental parameter method,and the standard samples are the same.The calculation of element concentration is simple and rapid,but the precision of the results depends relatively largely on the concentration range of the standard samples by this method.
