Abstract: The action mechanisms of physical fields including magnetic field，electric field，electromagnetic field，ultrasonic field and high gravity are briefly introduced，respectively. Research progress of enhancement of gas-liquid mass transfer in evaporation，distillation and gas absorption by these physical fields is reviewed. The progress of thermodynamic study involved is also introduced. The enhancement by physical fields should have a wide application prospect in chemical industry，environmental protection，energy-saving and emission reduction. However，most of current studies are still in the experimental stage，and the researches on the influence of various factors on the enhancement and the mechanism involved are not deep enough. Exploring the enhancement mechanism，expanding the application areas，solving the bottleneck problem and comparing the enhancement effects of different physical fields by experiment and thermodynamic analysis to determine the applicability of each physical field should be the focus of future research.

Key words: gas-liquid, mass transfer, physical field, process enhancement
