| Abstract: | 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. |
