自1974年华裔美国学者 Frank·H·Chung 提出基体冲洗法以来,他的混合物相定量分析技术,引起国内外广大 X 射线分析工作者的极大兴趣。人们习惯地简称为 K 值法。K 值法在我国冶金系统应用较广,1985年制定了金属材料定量相分析—X 射线衍射 K 值法国家标准。K 值法的主要特点是引入了一个新参量 K,即所谓参比强度。与其它定量分析方法相比,K 值法不作标准曲线,计算方便,单矿物用量较少。只要有参比强度值(K 值),便能测出混合样中某一物相的含量或非品质的存在。K 值法定量精度取决于参比强度值的测定方法及其准确性。基于这些考虑,笔者应用 D/MAXRA 型高功率(12K)
Since the Chinese-American scholar Frank H. Chung proposed the substrate flushing method in 1974, his mixture phase quantitative analysis technology has aroused great interest of X-ray analysis workers at home and abroad. People are often referred to as K-value method. K value method is widely used in China’s metallurgical system, in 1985 developed a quantitative analysis of metallic materials-X-ray diffraction K value of the national standard. The main feature of K-value method is the introduction of a new parameter K, the so-called reference intensity. Compared with other quantitative analysis methods, K value method does not make the standard curve, the calculation is convenient, the amount of single mineral is less. As long as the reference intensity value (K value), can be measured in a mixed sample of a phase content or non-quality existence. The accuracy of the K-value method depends on the method of determining the reference intensity value and its accuracy. Based on these considerations, I use D / MAXRA type high-power (12K)
