The phase equilibria in the quinary Na, K, Mg//Cl, SO4–H2O sea-water system at 0 °C were determined and a total phase equilibria diagram for the system was constructed by means of the translation method consistent with available literature data. There are seven points, 21 curves and 22 fields saturated, respectively, with 4, 3 and 2 equilibrium solid phases, for the quinary composition of the system. The constructed total phase equilibria diagram of the system was fragmented into divariant co-crystallization fields of two different solid phases and trivariant crystallization volumes of each of the solid phases at equilibrium. The structures of nine Janecke dry-salt phase diagrams were obtained by fragmentation of the total phase equilibria diagram into crystallization volumes. The comparison with the available literature data shows that, the obtained crystallization volume for halite agrees well with the available experimental data.

0 °C 时海水 Na, K, Mg//Cl, SO4–H2O 五元体系中的相平衡

确定了五元 Na, K, Mg//Cl, SO4–H2O 海水系统在 0 °C 的相平衡，并通过与现有文献数据一致的平移方法构建了该系统的总相平衡图. 系统的五元组成有7个点、21条曲线和22个饱和场，分别有4、3和2个平衡固相。构建的系统总相平衡图被分解为两个不同固相的二变共结晶场和平衡时每个固相的三变结晶体积。九个 Janecke 干盐相图的结构是通过将总相平衡图分解为结晶体积而获得的。与现有文献数据的比较表明，
