摘　　要：在进行大集里盐湖夏季组成卤水的天然蒸发实验中确定，该卤水的蒸发结晶路线不是按照Ｎａ＋、Ｋ＋、Ｍｇ（２＋）／／Ｃ１－、ＳＯ４（２－）──Ｈ２Ｏ体系２５℃平衡溶解度相图，而是按照该体系的介稳相图预示的亚稳过程进行。从天然蒸发过程中盐卤的浓缩倍数与浓缩卤水中硼富集倍数的一致性认为，盐卤在天然蒸发浓缩业折过程中硼酸盐一般地并不以固体业形式析出，而是赋存于浓缩卤水中。Based on the solar evaporation result of the brine taken from Da Chaidam salt lake in summer, the solar pond system with three stages has been designed and COnstructed' And then , the solar eveporation technologic experimant has been conducted, and the evaporation amount of brine,the amount of salt crystallized out and the concentrated brine obtained from each stage has been determined. At last, the optimum relative area ratio of leach stage in solar pond system has been given.
