摘　　要：本文对物理化学教材中的电解质的化学势及活度的两种定义进行了推导与讨论,指出μ=v+μ+v.μ可适用于强弱电解质体系,但μ涵义不同。两种电解质活度定义中,P·M·ATKINS 活度定义更合理,可以给教学带来更大方便。The article deduces and discusses the chemical potential of electrolyte and two definitions of its activity in most teaching materials on physical chemistry.It points out that μ=v_+μ_++v_μ_ can be the same with feeble and strong electrolyte systems,but the meaning of μ is different.Of the two definitions,P ·M· ATKINS' definition is more reasonable and can be more convenient for teaching.
