中文摘要:

      利用Ｐｉｔｚｅｒ的离子相互作用理论和化学热力学理论，计算了各实验点晶间卤水中相关离了的活度，以及晶间卤水对光卤石的饱 和指数，得出了与实验结果一致的结论。

英文摘要:

      In this paper, the activity coefficients of interrelated ions and saturation coefficient of cavnallit in brine which is among salt grains, are calculated by using Pitzer's theory of ion interaction and chemical thermodynamics for each experiment point that are in Qarhan salt lake. The results of calculating and observing in experiment show no difference.The following conclusion is obtained: In the process of mining brine, as different brines mix each other, the super-saturated mixed brine is formed at some certain beneficial section; and the beneficial components, like K Mg, etc., can be separated out as the type of cavnallit.
