| 摘 要： | 通过一个组分在不同温度下的无限稀释活度系数，利用非线性回归确定了四氢呋喃１，４丁二醇、水１，４丁二醇二元体系的ＵＮＩＱＵＡＣ、ＮＲＴＬ溶液模型参数．用所获得的两溶液模型参数对三元气液平衡数据进行理论推算，并与实测的三元气液平衡数据进行比较，发现两结果比较吻合．

| Abstract: | The model parameters for UNIQUAC and NRTL equations are obtained by using the infinite dilute activity coefficients of a component at several temperature and the nonlinear regressive technique.The vaporliquid equilibrium(VLE) data calculated by using the parameters for UNIQUAC or NRTL equation is agreement with that from VLE experiment. |
