根据 X射线小角散射 (SAXS)原理 ,采用分割分布函数法 ,测定了氧化铝粉末中的微孔尺寸 (4nm～ 2 30 nm )和尺寸分布。方法简单易行 ,合理可靠 ,能准确测定微孔的尺寸分布
According to the principle of small-angle X-ray scattering (SAXS), the pore size (4nm ~ 230nm) and size distribution in alumina powder were measured by the method of split distribution function. The method is simple, reasonable and reliable, and can accurately determine the pore size distribution
