摘 要: 用X射线荧光光谱测试了特种钡玻璃中的Si， Al， Sr， Zr， Ba， Na和K七种元素。采用熔融法制样，用人工标样作为校正标准，DRALPHA软件计算理论α系数，C-Q方程校正元素间的吸收-增强效应。结果表明，与经验α系数校正法相比，理论α系数法的测定结果与化学分析法的测定结果更为一致。

Abstract:In order to correct matrix effect for determining Si,Al,Sr,Zr,Ba,Na and K in barium glass by X-ray fluorescence (XRF), the theoretical alpha coefficient method was used. In experiment glass samples were prepared by melting, artificial standard samples were used as standard for calibration, DRALPHA program was applied to calculate theoretical alpha coefficients, and C-Q equation was applied to correct the effect between elements. Compared with the empirical coefficient method, the results obtained from theoretical alpha coefficient method are more agreeable to those of chemical analyses.
Key words: X-ray fluorescence theoretical alpha coefficient barium glass
