摘　　要：为了研究东台吉乃尔盐湖卤水蒸发时的相化学，确定钾、镁和锂盐的结晶特性，在实验室内２５℃等温蒸发实验基础上和自然条件下进行了冬夏季日晒蒸发试验．东台吉乃尔盐湖卤水是由氯化钠饱和的多组分复杂体系构成的．卤水中存在的离子是Ｎａ＋、Ｋ＋、Ｍｇ２＋、Ｌｉ＋、Ｃａ２＋、Ｂ３＋、ＳＯ４２－和Ｃｌ－．试验数据与Ｎａ＋、Ｋ＋、Ｍｇ２＋Ｃｌ－、ＳＯ４２－ＫＨ２Ｏ五元体系介稳平衡数据进行了讨论和比较．Ａｕｔｅｎｒｉｅｔｈ相图被用来表示各数据间的关系和证明冬夏季蒸发时结晶行为的差别．In order to study the phase chemistry of Dongtaijinaier salt lake brine as it evaporated. and to determine the crystallization characterstics of potassium.,magnesium and lithium salts, on the basis of isothermal evaporation at 25℃ in the laboratory, a complete solar evaporatoin test in summer and winter was made respectively in the laboratory and the natural conditions.The brine constitutes a complex multicompoent system saturated with sodium chloride. The ions presenting in this brine are Na+. K+. Mg2+, Li+, Ca2+. B3+. SO42- and Cl-. These experimental results are discussed and compare with metastable equilibrium data of the quinary system Na+, K+. Mg2+Cl-. SO42- -H2O. An Autenrieth typedigram was used to show the correlation of all the brine data and to illustrate the differences between summer and winter solar evaporation.
