Like the UNIFAC group-contribution equation of state, it performs satisfactorily in the VLE prediction of systems containing polar components, including VLE under high pressures.

用此法预测了含极性组分体系常压到较高压力的汽液平衡，结果良好，与UNIFAC基团贡献状态方程的结果相当。

Furthermore, the correlation and prediction are made by using UNIFAC model and UNIFAC MH81 group contribution equation of state, the results of which are in good agreement.

并分别用UNIFAC模型和UNIFAC - MH81基团贡献型状态方程作了关联和预测，结果符合得较好。

The results show that the VLE data can be predicted satisfactorily by theMH equation based on UNIFAC model, while the LLE data based on NRTL model.

研究结果表明：基于UNIFAC模型的MH方程能较好地预测汽液平衡，而基于NRTL模型的MH方程能满意地关联液液平衡数据。
