A SOLUTION OF MINIMUM NORM FOR QUANTITATIVE PHASE ANALYSIS BY STANDARDLESS X-RAY DIFFRACTION
无标X射线衍射定量相分析的极小范数解

A new expression of quantitathe phase analysis by standardless X-ray diffraction has been derived using intensity matrix of vector modulus. The criterion of 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 be obtained by the least squares regression.
