评述了将电解质溶剂化能分解为离子组分和比较不同溶剂中单个离子活度的热力学外方法。本文对玻恩方程的应用作了限制，使比较的或然可靠性大为提高。从乙腈到水的转移自由能与潜在的有用的参考对，包括铷，铊，二茂铁，和Ferroin系统，进行了评估。讨论了这两种耦合的相对优点。
Extrathermodynamic methods that have been used to split solvation energies of electrolytes into the ionic components and to comparesingle ion activities in different solvents are reviewed critically. In this work, the application of the Born equation is restrictedin such a manner that the probable reliability of the compari-sons is improved significantly. The freeenergy of transfer from acetonitrile to water associated with potentially useful reference couples, including the rubidium, thallium, ferrocene, and ferroin systems, is evaluated. The rela-tive advantages of these couples are discussed.
