摘　　要：测定了２９３．２～３２３．２Ｋ间的７个温度下电池ＧＥ｜Ｈ２Ｏ（１－ｗ）＋Ｅｎ（ＯＨ）２（ｗ）＋ＨＣｌ（ｍ）｜ＡｇＣｌ－Ａｇ的电动势，由此求得了上述７个温度下，ｍ＝０．００２０，０．００５０，０．０１００，０．０５００，０．１０００ｍｏｌ／ｋｇ的ＨＣｌ在０～９０％乙二醇—水二元混合溶剂中的平均活度系数γ±与Ｐｉｔｚｅｒ参数；ＨＣｌ自水向各组成Ｅｎ（ＯＨ）２—Ｈ２Ｏ混合溶剂中的标准迁移自由能，标准迁移熵和标准迁移焓．最后从分子间相互作用的角度对ＨＣｌ在该混合溶剂中的热力学行为给予了理论解释．The EMF of the cell: GE | En (OH)2 (w) +H2O (1 -w) +HCl (m) | AgCI - Aghave been determined at seven temperitures from 293. 2～323. 2K in tenethylene glycol+water mixtures from 0 to 90 weight percent of the ethlene glycol. The Pitzer's parameters and the activity coefficients of HCl at 0. 002 0, 0. 005 0,0, 010 0, 0. 050 0 and 0. 100 0mol/kg are worked out, the standard thermodynamic functions for the transfer of HCl from water to the respective solvents are calculated. The results have been discussed on the view of the solvte -solvent interactions.
