The empirical equations for secondary nucleation and crystal growth kinetics were determined by moment method.
采用矩量法确定了盐酸大观霉素溶析结晶二次成核和晶体生长动力学经验方程。
Primary nucleation was the main nucleation mode in the precipitation process. However, secondary nucleation cannot be ignored when the slurry density is high, and the supersaturation is low.
动力学研究表明，在硝酸硫胺沉淀结晶过程中，初级成核是主要的成核方式，当晶浆密度较高且过饱和度很低时，二次成核不能忽视。
