关于电解质溶液活度问题,Debye—Hchel方程具有基础意义。当把此方程应用于实际溶液时,出现了许多推广形式。Davies公式就是一个Debye-Hckel方程的具体形式: The Debye-Höchel equation has fundamental implications for the activity of electrolyte solutions. When applying this equation to real solutions, there are many forms of generalization. The Davies formula is a concrete form of the Debye-Hckel equation:
