Classical theory of flocculation is based on the assumptions of globe shape of colloidparticle.
传统混凝理论是在经典胶体化学的基础上，假定胶体颗粒为球形建立的。

The colloidparticle size and flow characteristics of zirconyl oxalate sol were investigated, and the performance of the membrane was characterized by SEM and gas-flow method.
实验表明用这种方法制备的草酸氧锆干凝胶具有触变的特性，是制备氧化锆膜的一种经济实用的前驱体。

It was pointed out that proper grafting of monomer onto protective colloid was vital to stability of colloidparticle. So it is important to properly use protective colloid in emulsion polymerization.
