摘　　要：系统地介绍了气液传质过程中,固体小颗粒或第二分散液相(有机相)所形成的第三相的加入对传质过程的影响。分别论述了在不同的气-液接触器(搅拌釜、鼓泡塔)中,固体小颗粒和第二分散液相的加入对体系的传质系数、传质速率及界面面积等的影响,叙述并讨论了传质机理及模型的最新进展。This paper systematically introduced the effect of the presence of small amounts of the third phase which may be solid particles or the second dispersed liquid phase （organic phase） on gas-liquid mass transfer processes. In different gas-liquid reactors （stirred reactor ／ bubble column reactor）, with the joining of the third phase and the second despersed liquided, the coefficient of mass transfer, the rate of mass transfer and interface areas have been affected. Furthermore, the mechanism of gas-liquid mass transfer was reviewed and the further developments were predicted.
