本文用X射线衍射矢量模强度矩阵来建立无标相分析表达式,提出了无标分析的判定标准,并从样品的衍射图谱中分离出各相的衍射图谱,采用最小二乘回归法求其最优解。
A new expression of quantitathe phase analysis by standardless X-raydiffraction has been derived using intensity matrix of vector modulus. The criterionof standardless X-ray diffraction analysis was suggested, so as to separate the diffra-ction pettern of every phase from that of sample. The optimal solution could beobtained by the least squares regression.
