摘要
分别测定了在３４０～３６０Ｋ范围内乙醇和氯化镁饱和乙醇溶液的蒸气压与温度对应数据；根据热力学原理本文推导出蒸气压法和沸点升高法精确计算乙醇活度的方程式；用本文导出的方程式和教科书中常见的方程式处理实验数据，结果有所差别。
The vapor pressure of alcohol and saturated solution of magnesium chloride in alcohol was respectively measured at the different temperature(340K to 360K).According to the principle of thermodynamics,some equations for calculating the activity from vapor pressure or boiling point were derived.There are a few differences between the results calculated by the different equations.
