摘　　要：Rayleigh B啨ｎａｒｄ Marangoni现象对吸收、萃取、精馏、蒸发等气液或液液传质过程具有显著的影响和重要性 ,但迄今 ,对RBM现象本质的认识还远远不能满足理论和工程上的要求 ,对其实验及理论研究将促进对传质微观机理的理解及加强实际应用。文中综述了对RBM现象实验和理论研究的成果 ,讨论了未来对其研究的方法和方向。Rayleigh-Bénard-Marangoni (RBM) effect has an important influence on gas/liquid or liquid/liquid mass transfer process happened in absorption, distillation, extraction, evaporation and so on. But up to now, the comprehension to RBM effect is still far from satisfying the request of theory and practice although RBM effect strengthens the mass transfer process in general. Experimental and theoretical study on RBM effect will intensify the understanding of microcosmic mechanism of mass transport and promote the practical application in chemical engineering. The results of experimental and theoretical study on RBM effect were reviewed and the future study methods were discussed as well.
