<正> 材料的织构是X射线定量相分析的障碍,虽然用全极图求平均强度的方法原则上可以解决,但制作极图费时,有时甚至不可能。因此人们常用一些方便的近似方法如反极图的极密度因子
The error of average intensity of X-ray diffraction spectra, in the case of not more enough, from specimen of Fe, Al or Zn having obvious texture was studied. The error of average intensity obtained from measured intensity dividing by polar density factor of the inverse pole figure is so large that it can not be used for quantitative phase analysis. The error of average intensity obtained using oscillation sample holder (the intensity is averaged mechanically over the region from 0 to 60 degree of the pole figure) is improved slightly for Fe or Al, but still large for Zn. The satisfactory result is obtained by means of "the double correction method". The error is 2-5% for Fe or Al, and less than 10% for Zn.
