Abstract

To increase the accuracy of electron probe microanalysis, it was proposed to calculate absorption coefficients range-by-range, with selecting an optimum calculation method for each absorption range. The approach was implemented in the analysis of rock-forming minerals using the PAP correction method. Calculations of absorption coefficients in the region below the K-edge were performed using the PAP method and, in K–L₁ range, by the Heinrich method with certain refinements. A series of natural minerals with high iron (and zinc) contents were used for refinement. Practical tests confirmed the expediency and reliability of the range-by-range calculation of absorption coefficients.

吸收系数的按距离计算，作为提高电子探针显微分析精度的一种方法

摘要

为了提高电子探针显微分析的准确性，提出了逐个范围地计算吸收系数，并为每个吸收范围选择最佳的计算方法。该方法是在使用PAP校正方法分析成岩矿物中实施的。在K边缘以下区域的吸收系数的计算是使用PAP方法进行的，在K–L ₁范围内，通过Heinrich方法进行了某些改进。使用了一系列铁（和锌）含量高的天然矿物进行精炼。实际测试证实了吸收系数逐段计算的便利性和可靠性。
