研究了X射线荧光强度与谱仪与试样之间距离的关系。计算初级X射线辐射强度、空气对X射线的吸收以及被分析材料的表面积的变化。提出了一种有效的方法来提高连续X射线荧光分析的准确性的铁矿石混合物在传送带上通过排除不正确的结果由检测单元的死区时间。该方法具有通用性，可用于各种松散材料。
The dependence of the intensity of X-ray fluorescence on the distance between the spectrometer and the test sample is studied. Changes in the intensity of primary X-radiation, absorption of X-rays by the air, and surface area of the analyzed material are calculated. An efficient method is proposed for improving the accuracy of continuous X-ray fluorescence analysis of iron ore mixtures on the conveyor belt through the exclusion of incorrect results by the dead time of the detection unit. The proposed method is universal and can be used for various loose materials.
