液体饱和蒸气压和平均汽化热测定实验装置的改进

he idea and project of brand-new designation for vapor pressure and average gasify enthalpy testing instrument were described in this article. The instrument was introduced to determine saturated vapor pressure of water, from which average mole gasify enthalpy and entropy of water were deduced, under different temperature from 60 to 100 centigrade. The results indicated that high precision of the testing, stable running of the system and safety in operation can be offered by the new instrument.
