The causes of HCO3 -and PO43- having influences on CaSO4 crystallization process are that the change of solution ion strength changes the solubility product of CaSO4.

HCO3-和PO43-影响硫酸钙结晶过程的原因在于溶液离子强度的变化使硫酸钙的溶度积发生改变；

And the fouling of CaSO4 have been studied in the Vapor-Liquid-Solid Three-Phase Flow.

研究了汽液固三相流条件下硫酸钙的结垢过程。

The results showed that CaSO3 had retarded setting action on C4AF but didn't influent C3A;

研究结果表明：亚硫酸钙对C_4AF有缓凝作用，而对C_3A基本不具缓凝作用；

The inhibitory effect of scale inhibitors on CaSO4 crystallization process is mainly on the nucleation process of inhibiting crystals.

阻垢剂对硫酸钙结晶的抑制作用主要以抑制晶体成核过程为主。

The variation of product layer diffusivity with these factors was explained by its dependence on the concentrations of defects in CaO and CaSO4 crystals.

产物层扩散系数的变化可以其受氧化钙及硫酸钙结晶缺陷的浓度的影响来解释。
