X射线定量分析中,重叠线的分离好坏对分析结果影响很大。本文在实验工作的基础上,比较介绍了三种定量分析线型分离方法,及其优缺点、适用范围。这三种方法是:已知K值分离法;纯相的衍射峰值之比分离法和峰形对称直接作图分离法。 Quantitative X-ray analysis, the separation of the overlap line is good or bad analysis of the results. Based on the experimental work, this paper introduces three methods of quantitative analysis of linear separation, its advantages and disadvantages, and the applicable scope. The three methods are: Known K value separation method; pure phase diffraction peak ratio separation method and peak shape symmetry direct mapping separation method.
