Smart Application of Origin8.0 Software in Drawing of Gas-liquid Equilibrium Phase Diagram of Two Liquid System

Combined with examples of gas-liquid equilibrium phase diagram of two liquid system,based on powerful graphics and data processing function of Origin8.0,three ways of drawing phase diagram were introduced.The specific operating steps with simplicity and practicability were also provided.Those methods were not only applicable to physical experiments but also could be used to data processing and graphing in other experiments and scientific research.
