摘　　要：本文综合重质碳酸钙颗粒团聚机理,分散稳定机理及分散效果评价方法,提出产生团聚的三个力的计算方法,并提出稳定过程的空间位阻机理的不确定性原因,最后提出微观和宏观结合的分散稳定评价方法。GCC particle dispersion principals for aggregating and remaining stable, dispersion quality evaluation methods are reviewed in the paper. The calculation methods of three forces resulting particle aggregation are expressed. Reasons for steric effects ineffective to stabilize dispersion are explained. Microscopic and macroscopic combination to evaluate the dispersion stability is suggested.
