| 摘 要： | 本文用微量星热法测定了在２９８．１５Ｋ时，α－氨基丙酸在纯水和卤化钾水溶液中的溶解焓，并求算了焓相互作用参数ｈ＿（ｘｙ）、ｈ＿（ｘｘｙ）和ｈ＿（ｘｙｙ）的值．根据理论推导了静电相互作用对ｈ＿（ｘｙ）值贡献的计算公式，并运用结构相互作用模型讨论了焓相互作用参数随电解质离子半径的变化规律．

| Abstract: | The enthalpies of solution of α Alaninc have been measured in water and in KCl, K Brand KIaqucouses at 298.15K. The enthalpic interaction parameters h_(xy),H_(xyy),and h_(xxy) of α-Alanine withthe salts have been evaluated.The results are discused in the view of electrostatic and structural interaction. |
