| 摘 要： | 用小角散射测量粒度分布，通常假定颗粒形状是球形，实际上颗粒形状是很复杂的．统计地将颗粒形状归并为类球形、类盘形和类杆形三种．指出了计算形散函数的一般方法；并计算了类球形颗粒的形散函数，给出调节参量δ，可供一般分析选用．

| Abstract: | In measuring the particle-size distribution by small angle X-ray scattering the particle form must be known.In general the form of particles considered to be spherical ,but in practice, the form of particles was very complexity.We statistcally separate the forms of particles into sphere-like; flat-like and rod-like ones. The general method for calculating the form scattering function has been given, and we have calculated the form scattering function for sphere-like particles, and given an adjustable parameter δ that can be used in general analysis. |
