X射线衍射K值法或称母体冲洗法是1974年由美国学者F.H.Chung提出的。目前被国内外广泛采用,尤其在冶金、地质、建材、石油、化工、航空、航海、军工等部门应用更多。十几年来有关这方面的学术论文、报告等已有数百篇。但由于各家在使用此方法过程中,实验条件、制样方法、仪器调试、数据收集和处理以及误差消除和处理等不尽统一,致使试验数据分散、试验误差偏大。所求K值相互不能对比等缺点。 “金属材料定量相分析—X射线衍射K值法”国家标准起草小组通过5年多艰苦、细致工作在总结几次大型全国性试验基础上,分析测试四千多个数据,最后写出了本标 X-ray diffraction K value method or mother wash method was proposed by the American scholar F.H.Chung in 1974. Currently widely used at home and abroad, especially in metallurgy, geology, building materials, petroleum, chemical, aviation, marine, military and other departments more. Over the past decade, there have been hundreds of academic papers and reports in this area. However, due to the various methods used in the process, the experimental conditions, sample preparation methods, equipment commissioning, data collection and processing, and error elimination and processing are not uniform, resulting in scattered test data, the test error is large. The value of K can not be compared with each other shortcomings. “National Standard Drafting Team for Quantitative Phase Analysis of Metallic Materials - X-ray Diffraction K-value Method” After more than five years of hard work and meticulous work, we analyzed and tested more than 4,000 data on the basis of several large-scale national tests and finally wrote this Standard
