严格的讲无热溶液并不存在。如果两种大小不同的分子混合时产生热效应,这样形成的溶液叫非无热溶液。对于非无热溶液,它与理想溶液的偏差可以认为是△H~E(?)0,△S~E(?)0两个独立效应的总结果。反映非无热溶液对理想溶液偏差程度的活度系数亦可分为两项来讨论。 Strictly speaking, hot solution does not exist. If two molecules of different sizes are mixed to generate a thermal effect, the solution thus formed is a non-pyrogenic solution. For the non-hot solution, the deviation from the ideal solution can be considered as the sum of the two independent effects of ΔH ~ E (?) 0 and △ S ~ E (?) 0. The activity coefficient, which reflects the degree of deviation of the non-hot solution from the ideal solution, can also be divided into two.
