用小型计算机将x射线荧光强度转换为浓度需要简单的公式来进行日常使用。考虑均匀样品中元素间效应的影响系数是通过在大型计算机上运行的ALPHAS程序从基本参数计算出来的。这些系数随后可用于简单的常规方程，用于大范围校准。理论系数是使用多元回归分析进行大范围校准的有价值的支持。所需标准的数量大大减少。证明了理论影响系数在不锈钢中的专用性。
The conversion of X-ray fluorescence intensities to concentrations by a mini-computer requires simple equations for routine use. The influence coefficients, accounting for inter-element effects in homogeneous samples, are calculated from fundamental parameters by means of a programme called ALPHAS operating on a large computer. These coefficients can subsequently be used in the simple routine equations for wide range calibration. The theoretical coefficients are a valuable support for wide range calibrations using multiple regression analysis. The number of required standards is significantly reduced. The exclusive use of theoretical influence coefficients is demonstrated for stainless steel.
