摘　　要：结合本校在双液系气液平衡T-x相图绘制实验的改革,通过对以往文献分析和总结,评价了近年来该实验在体系选择、沸点仪的改进、待测样的配置技巧以及数据的自动化处理等方面取得的进展。该实验的每一处改进均体现出对相平衡理论的深刻理解以及实验室绿色环保意识的不断提高。Combining with the reform of the experiment in our laboratory,the improvements of the gas-liquid equilibrium phase diagram with binary liquid system about the choice of the experimental system,the reform of ebulliometer,the distribution of the solution and the data processing,were reviewed and summarized by analyzing the references.Each reforming of the experiment showed the deeply understanding of the theory of phase equilibrium and the rapidly improvement of mankind＇s sense of environmental protection.
