由于电子计算机在 X 射线荧光分析中的应用,用数学公式来校正元素的基体效应已越来越广泛,其中基本参数法由于一些物理参数尚不确定,且需要复杂的计算,一般计算机不能胜任;α系数法也需要大量的数据处理,一般实验室使用有一定困难。下面两个数学公式:c_i=sum from r=0 to 2 a_(ir)I_i~r+I_i ∑m _(ij)I_j+∑b_(ij)I_j (1)c_i=sum from r=0 to 2 a_(ir)I_i~r(1+∑f_(ij)c_j)+∑b_(ij)C_j (2)只要有一套合适的标准,用小型计算机多重回归法求
Due to the application of electronic computer in X-ray fluorescence analysis, the matrix effect of element correction by mathematical formulas has become more and more widespread. The basic parameter method is not suitable for computers because of some uncertain physical parameters and complex calculations. Alpha coefficient method also requires a lot of data processing, the general laboratory has some difficulties. The following two mathematical formulas: c_i = sum from r = 0 to 2 a_ (ir) I_i ~ r + I_i Σm _ (ij) I_j + Σb_ (ij) I_j c_i = sum from r = 0 to 2 a_ (ir) I_i ~ r (1 + Σf_ (ij) c_j) + Σb_ (ij) C_j (2) As long as there is an appropriate set of criteria,
