摘　　要：采用连续滴定量热法测定了２９８．１５Ｋ仰光卤石极限浓溶液的稀释热（１．８９４２→０．０１０４４ｍｏｌ·ｋｇ（－１）），建立了该溶液的稀释热曲线方程，并发现相同起始浓度的单纯ＫＣｌ、ＭｇＣｌ２溶液稀释焓之和等于该浓度光卤石溶液的稀释焓，稀释焓曲线方程与天然光卤石溶液稀释方程相吻合．Abstract This paper used continuous titration catorimetry to determine the heat of dilution, heat capacities of solution of KCl·MgCl2·6H2O system and solution of composes at 298.15k. It was measured to cover solution concentration. from 1. 8942-0. 01044mol·kg(-1), and establish equation of curve.
