【摘要】 本文提出了通用的无标样X射线衍射定量相分析的新方法。它克服了Zevin无标样定量分析方法要求参考试样与待测试样相组成完全相同的限制条件的缺点。参考试样相对于待测试样相组成而言,可以缺相,也可以多相(不纯)。因而本文的方法具有普遍性和适用性。对物相质量吸收系数已知和未知两种情况分别作了讨论。实例定量分析表明,无标样定量新方法简便实用,通用性强,并可得到精确满意的定量结果。更多还原

【Abstract】 In this paper, a new general method of X-ray quantitative phase analysis without standards is presented. The limit conditions that the phase composition of each of the reference samples and the analysis sample must be equal in Zevin’s method are no more to be required. When the analysis sample contains n₀ phases, each of the reference samples could contain less or more phases than n₀. Hence, our new method is more general. The quantitative methods in both cases of known and unknown mass absorption coefficients are discussed. Practical quantitative analysis have proved that, the new method is quite explicit and applicable as well as gives quite precise and satisfactory quantitative analysis results.更多还原
