在XRF分析中,对于同一试样中的某一分析元素的辐射强度来说,由于受到多种因素的影响,使辐射强度与浓度之间的线性关系发生变化。它不仅影响到分析结果的精密度和准确性,而且也增加了许多不必要的重复性劳动。当前,我们所采用的标准化样品及标准化测量方法,是解决上述问题的好方法。本文通过一系列的实验对标准化测量方法的原理,作用和意义进行了广泛的研究和讨论。 In XRF analysis, the linear relationship between radiation intensity and concentration changes for a given analyte in the same sample due to a combination of factors. It not only affects the precision and accuracy of the analysis results, but also adds a lot of unnecessary repetitive work. At present, the standardized samples we use and the standardized measurement methods are a good way to solve the above problems. In this paper, a series of experiments on the principle of standardized measurement methods, the role and significance of a wide range of research and discussion.
