本文叙述了放射性同位素源激发能量色散X射线分析中基本参数法的原理、实验装置和计算机程序。在实验数据计算中,考虑了二次荧光的贡献,忽略了三次荧光强度。在本实验中,分析了砷化镓、碲化镉和不锈钢样品,结果与已知值进行了比较,准确度和精密度约在1%左右,样品分析时不需要标准,方法是非破坏的、可靠和有效的。
In this paper
the principle
experimental arrangement and computer program of fundamental parameters method in radioisotope source excited energy dispersive X-ray analysis are described. In the calculation of the experimental data
the secondary fluorescent X-ray intensity was considered with the tertiary neglected. Both GaAs and CdTe as well as stainless steel specimens were analyzed by this method. The results were compared with the known values. The accuracy and precision were about 1%
respectively. No calibration standards were required. The method is non-destructive. The results demonstrate that this method is reliable and efficient.
