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 texture of the material is an obstacle to the quantitative X-ray phase analysis. Although the method of obtaining the average intensity using the polarogram can be solved in principle, it is sometimes time-consuming and sometimes impossible. Therefore, people often use some convenient approximation methods such as extreme density factor of the reverse pole figure
