That is to say, in SDS-CaCl_2 system, the crystallization phenomenon resulted from the solubility product of Ca_2 salt, is the main mechanism of surfaetant precipitation.

即可以认为，在SDS-CaCl_2体系中，Ca_2的溶度积效应导致的结晶现象，是表面活性剂沉淀的主要机理。

At high CaCl_2 concentration, when the product of the free Ca~(2+) ion concentration in solution and the monomer surfactant concentration exceeds the solubility product of Ca_2 salt, Ca_2 precipitates can be salted out in this system.

在较高的CaCl_2浓度下，溶液中游离的Ca~(2+)离子浓度与表面活性剂单体浓度的乘积超出Ca_2的溶度积时，体系中会析出Ca_2沉淀。
