摘　　要：对如何采用X射线荧光仪检测钢中的各主要稀土元素,然后再计算出稀土总量的方法进行了研究。通过对分析条件、最佳计数时间、试样研磨深度等项目进行探讨,建立了一套快速分析钢中稀土总量的方法。实践证明,该方法可快速、准确地检测出含量在0 005%以上的稀土总量,完全可以满足生产的需要。How to analyse each of main rare earth elements by Xray fluorescence, and to calculate total content of earth elements according to experimental results were studied. A rapid method for determining rare earth elements has heen established through the experiments for analytical condiction, best counting time and grinding depth of sample. It was proved that proposed method can determine more than 0.005% of rare earth elements quickly and accurately, and can meet the needs of production.
