摘　　要：引入分析策略的概念 ,揭示了当代研究X射线衍射定量相分析方法的正确途径。通过策略的系统演绎 ,对现今X射线定量相分析的基本方法进行了全面的构筑和科学分类 ,总共有 7类分析方法 ,分别称之为内标消约法、外标消约法、样内异相消约法、样间异相消约法、样间同相消约法、归并C值法和理论计算法 ,并对各类方法的固有特点作了全面的概括。A new concept of analytical tactics on quantitative phase analysis by X ray diffraction was put forward in this paper.It was expounded that the studies of analytical tactics,the abstracted forms of analytical methods,should occupy a leading position in the studies of the methods for quantitative analysis by X ray diffraction.Based on the systematic deduction of tactics, the methods for quantitative phase analysis were worked out completely and according to analytical tactics they were classified into seven types: internal standard reduction, outer standard reduction, hetero phase reduction within a sample, hetero phase reduction between samples, homo phase reduction between samples, merge C value and theoretical calculation. The features for each tyep of methods were summarized and the development of routine quantitative method combined with modern powder diffraction pattern fitting technique were also discussed.
