采用电子探针显微分析（EPMA）研究了固溶体中碳含量低于1wt%的渗碳钢中的碳含量。本文叙述了用X射线强度的k比和φ（ρz）模型进行经典分析所遇到的困难。本文介绍了一种适用于标准试样金相研究和试样碳净化的校正曲线法。
The carbon contents in carburized steels were investigated by electron probe microanalysis (EPMA) for a range of carbon levels in the solid solution less than 1 wt%. This article describes the difficulties encountered with the classic analytical procedure using the k ratio of X-ray intensities and the φ(ρz) model. Here, a suitable calibration curve method is presented with emphasis on the metallographic study of standard specimens and on the carbon decontamination of samples.
