| 摘 要： | 在Popovic增量法的基础上提出一种新的X射线衍射定量相分析方法，对已知和未知待测样品所含非晶相的质量吸收系数的两种情况进行了讨论，可测定样品中的非晶相或未知相的含量.可用于含非晶相样品的X射线衍射定量相分析，而且对含有n相，其中有非晶相的样品，只需一次增量其中的n-2个晶相，即可测定样品的全部物相含量.实验验证采用四组分和五组分的样品，实验结果与理论完全一致.

| Abstract: | A new approach for quantitative X-ray diffraction phase analysis of a powder mixture has been developed using the doping method proposed by Popovic.Two cases of known and unknown mass absorption coefficients of amorphous materials are discussed.The weight fraction of amorphous material or unidentified phases can be obtained by this method.For the determination of multicomponent system containing n phases,in which (n-2) pure phases are deliberately added,the weight fractions of all n phases can be determined.The procedure has been tested by using four-to five-component samples,the analysis results agree well with the theory. |
