一、引言: 在化工、冶金和其它方面的X射线定量相分析工作中,常会遇到样品数量很少的情况。因此,微量样品的相分析研究工作开始受到了重视。本文讨论了微量样品(2—3毫克)在X射线定量相分析中应用的可能性,旨在促进这方面工作的展开。在X射线定量相分析中,自1974年,F·H·Chung提出了定量相分析方法——基体冲洗法(K值法),使得相分析工作一改过去的琐碎、费时而变得简捷、快速并能给出可靠的结果。本试验即采用这种方法。其具体公式为: I. Introduction: In the chemical, metallurgical and other aspects of quantitative analysis of X-ray phase, often encounter a small number of samples. Therefore, the phase analysis of trace samples began to pay attention to the work. This article discusses the possibility of using trace amounts of samples (2-3 mg) in X-ray quantitative phase analysis to promote the work in this area. In X-ray quantitative phase analysis, F H Chung proposed a quantitative phase analysis method (K value method) since 1974, making the phase analysis work a trivial, time-consuming and simple, Fast and gives reliable results. This test is to use this method. The specific formula is:
