一、前言科学技术的发展和新材料的广泛应用,迫切需要知道原材料、成品中各物相的含量,其他手段无法完成这一任务,而 x 射线衍射定量相分析却有独特之处.x 射线定量相分析方法很多,应用最广的是基体冲洗法(即 K 值法),但都基于试样无织构存在的前提下进行的,然而试样中 I. INTRODUCTION The development of science and technology and the extensive application of new materials urgently need to know the content of each phase in raw materials and finished products, and other means can not accomplish this task. However, the quantitative analysis of x-ray diffraction has its own unique characteristics. There are many methods of quantitative phase analysis, the most widely used is the substrate washing method (ie, K value method), but based on the sample without the existence of the existence of the premise, but in the sample
