摘　　要：汽液平衡数据是化工分离过程中的重要基础数据,对于化工生产和化工设备的设计极其重要。详细介绍了实验中心从二元体系的选择、实验装置的结构改进、汽液平衡组成分析方法以及实验数据的处理方面对"二元汽液平衡数据测定"实验进行的改进,改进后的实验有利于提高数据测定的准确性,同时提高学生的学习效率和实验教学效果。Vapor-liquid equilibrium data (V.L.E.) are the basic information of the system required for the design of equilibrium stages of vapor liquid separation equipment, which is of significant importance to chemical processes and chemical engineering design. The improvements of the “Measurement of Vapor-Liquid Equilibrium Data for Binary System” in our experiment center are detailed, which include the choice of the binary system, the improvements of experiment device, the analysis of equilibrium compositions and the data processing. The reforms would improve the accuracy of data determination, the students’ learning efficiency and experiment s teaching effect.
