摘　　要：本文探讨了用XRF法分析不锈钢时，用个别交叉项系数校正Cr、Fe、Ni之间的交叉效应，从而有效地修正了它们之间的吸收一增强效应，使分析结果得到改善，最大误差不超过0．5％。与C－Q方程相比，该法计算简便，具灵活性和实用性，可推广使用。The cross-effect of Cr, Ni, Fe elements was explored in using DJ, JIS correction models for XRF analysis of stainless steel, and based on the C-Q equation, a similar XRF correction equation was developped, and the cross-effect of Cr, Ni, Fe was effectively cor rected. The analytical results of stainless steel were greatly improved, and the maximum er ror was only 0. 5%. The method is simple, covenient, flexible and practical, and can be widely applied.
