| 摘 要： | 提出了一种预测二元及三元物系形成共沸点的新方法。共由沸点定义，推导出二元及三元物系形成共沸点的条件，以及共沸点个数是奇数还是偶数。在存在共沸点的条件下，利用活度系数关联式，通过泡点计算求出共沸条件。实例计算结果表明，预测结果与文献结果基本一致。

| Abstract: | A new algorithm for predicting of azeotropy in binary or ternary systems is investigated based on the definition of azeotropy. The possibility of unique azeotropy or polyazeotropy in a liquid mixture can be predicted using activity coefficient models in terms of boiling point calculation. The results of calculation are in good agreement with those in reference. |
