This article made great lengths to introduce UNIFAC model, including it’s theory、developing、advantage and disadvantage, and translate and edit the design procedure UNIFAC model to be software(UNIFAC Model Calculation Software) by VB . This software through data searching and computing to calculate the activity coefficient、chart of activity coefficient、VLE isotherm(isobar) ,for the use and improve the UNIFAC model provide great help. Key words: VLE; Calculation Software ; UNIFAC; Activity coefficient; 目 录 中文摘要 I
