一、概述 X射线荧光技术的定量分析数学方法早在五十年代就提出来了。六十年代随着半导体探测器的出现,多元素分析技术已经得到很大发展。利用数学方法对样品测量的结果进行基体效应的校正,这在室内用计算机处理是很容易实现的。但对野外使用的便携式仪器则比较困难。近年来,微型计算机技术的发展使X射线荧光技术在方法上得到完善, I. Overview Quantitative Analysis of X-Ray Fluorescence Techniques Mathematical methods were proposed as far back as the 1950s. Sixties with the advent of semiconductor detectors, multi-element analysis technology has been greatly developed. The math method is used to correct the matrix effect on the result of the sample measurement, which is easily handled by computer in the room. However, the use of portable instruments in the field is more difficult. In recent years, the development of micro-computer technology makes X-ray fluorescence technology improved in the method,
