摘　　要：介绍了用能量色散X射线荧光光谱法（EDXRF）同时测定W—Mo—Ni—Fe合金组分的分析方法。当W、Mo、Ni和Fe的质量分数依次为70％～90％、7％～21％、2％～6％和1％～3％时，其测量结果的相对标准偏差依次不大于0．5％、1．5％、3％和4％。该方法快速、简便。A method determining W, Mo, Ni and Fe contents at the same time for W-Mo-Ni-Fe alloy by using energy diffuse X-ray fluorescence （EDXRF） spectroscopy is described. The results show that this method is rapid, simple and convenient. The relative standard derivations are less than 0.5%, 1.5%, 3% and 4% when the mass ratios are in the range of 70%-90%, 7%-21%, 2%-6% and 1%-3% for W, Mo, Ni and Fe, respectively.
