摘　　要：通过对相关文献的分析及资料的查阅,总结了作为学生实验用双液系气-液平衡相图体系的选择要点。本文选用环己烷-乙酸乙酯双液系,进行气-液相图绘制。经实验证明,笔者认为此体系是一个适合本科教学开展的物理化学实验。Based on the relevant literatures and data, the key points of choosing binary vapor-liquid phase equilibrium diagram for students’ experiment has been summarized. Cyclohexane-ethyl acetate as binary liquid system, the vapor-liquid equilibrium phase was diagramed. The result is proved that this system is a suitable physical chemistry experiment for undergraduate teaching.
