| 摘 要： | 本文论证了样品对入射射线的质量吸收系数(μ_O)与康普顿散射强度之倒数呈线性关系,提出并验证了样品对待测元素特征线的质量吸收系数(μ_K)与质量吸收系数(μ_O)以及待测元素含量之间呈线性多项式关系。并且给出了这些关系存在的条件。提出了一种适用于低能量分辨率的携带式X荧光仪的散射校正模型。并成功用于锡矿和某些铜矿分析中。

| Abstract: | The portable double channel X-ray fluorescence analyzer with filters can measure the characteristic X-ray and scattering intensity quickly. The mathematic model for correcting matrix effects was reported by using calculated mass absorption coefficients of samples and very good results are obtained. |
