摘　　要：通过用沸点计公式求得的γ∞与其有关文献值的比较及эT／эx2与x2、γ∞2与эT／эx2关系的探讨发现，沸点计法计算γ∞公式对大沸点差特别是沸点差大于50℃的体系不适用.The infinit dilution activity coefficent(γ∞) of calculated by ebulliometer formula ware comparied with that of literature, the relation of эT/эx2 to x2 and that of γ∞2 to эT/эx2 ware discussed in the article. The result showed that the ebuliometer formula is unsuited to calculating γ∞ for the systems of having large difference of bubble piont.
