A systematic study of X-ray intensity ratios of the K-series lines was made on compounds of nickel and cobalt to examine the influence of chemical state and 0.6 and 1.2 T external magnetic fields on energy-dispersive X-ray fluorescence analysis. The samples were excited by 22.69 keV X-rays emitted from a Cd-109 radioisotope source and characteristic K X-rays emitted from the samples were counted by means of an Si(Li) detector. For B=0, the present experimental results were compared with the experimental and theoretical data in literature. The results demonstrate a clear dependence of the Kbeta/Kalpha intensity ratios on the chemical state of the element in the sample and values of external magnetic field.
对镍和钴的化合物进行了K系谱线X射线强度比的系统研究，以考察化学状态以及0.6和1.2 T外部磁场对能量色散X射线荧光分析的影响。样品由Cd-109放射性同位素源发射的22.69 keV X射线激发，样品发射的特征K X射线用Si(Li)探测器进行计数。对于B = 0，将目前的实验结果与文献中的实验和理论数据进行了比较。结果表明，Kβ/Kα强度比明显依赖于样品中元素的化学状态和外部磁场值。
