In preliminary experiment, the influence on sedimentation diameter of the value of pH, concentration of reactant and salt, species of acid, agitation, and additives were studied and the maximum of diameter was found with the advent of aging.

• 通过初步实验分别考察了陈化时间、pH值、反应物浓度、盐浓度、搅拌、添加剂、酸种类等对沉降粒径的影响，发现沉降粒径随陈化时间出现极值，从分形聚集的角度分析了凝胶和陈化过程，并对各种实验现象作了定性解释。
