摘　　要：通过设计新型结构的平衡管,解决了液体饱和蒸气压的测定实验中存在的平衡管加样及清洗困难、气体倒灌、蒸气不纯等问题,一次加样就可完成饱和蒸气压测定工作,操作便利,效率提高,所得实验数据准确性好。Due to the advantage of new structure about isopiestic pressure gauge,the annoyance problems such as the difficulty in injecting sample and washing,the backward flow of gas,the impurity of liquid vapor and so on,were solved in the experiment on measuring saturated vapor pressure of pure liquid. By using the new type isopiestic pressure gauge,operator can finish his measurement work with one time injection of sample. The application of this new type isopiestic pressure gauge implied facilitates of manipulation,enhancement of efficiency and accuracy of data.
