The particle size can be determined according to the scattering intensity, while shape information can be obtained through asymmetry factor (AF).

粒径的大小可由散射光强度确定，而颗粒的形状可通过对非对称因子af的分析获得。

The micro-images of particle morphologic and fractal are applied to process of image processing. Morphologic parameters have been brought forward: area, girth, diameter, shape factor, and fractal.

并应用了颗粒形态学及分形理论，检测颗粒的相关形态参数：颗粒的投影面积、周长、粒径、形状因子、以及分形维数。
