General Activity and General Activity Coefficient

In this paper the new concepts, general activity and general activity coefficient, have been proposed and the relationship between general activity coefficient and clectrolytic activity coefficient has been conducted. In terms of the general activity definition, the solvated hypothesis, a_s^h＝a_s1^h1a_s2^h2, has been accounted for. It is very important to the study of solvated micro-process and other related theoretical process in electrolyte containing mixed solvent systems.
