摘　　要：气液界面的传质行为显著影响化工反应与分离过程的效率,从而影响化工设备的设计、优化和操作。随着微纳科学和技术的发展,气液界面传质行为的研究从毫米尺度得以深入到微纳米尺度。研究人员发现传统的宏观连续模型难以描述与解释微纳气液界面传质行为,因此发展适用于微纳尺度的新模型意义重大。本文综述了近年来关于微纳尺度气液界面传质行为的研究进展,具体内容包括:(1)微纳气液界面结构和分子富集现象;(2)表面张力及表面张力差、密度差等引起的界面不稳定现象;(3)现有的气液界面传质理论与微纳尺度下气液界面传质的研究进展。The mass transfer behavior at gas-liquid interfaces significantly affects the efficiency of chemical reaction and separation processes,thereby influencing the design,optimization,and operation of reactor and separator.With the development of nanoscience and technology,research into gas-liquid interfacial mass transfer behavior had delved into the nano-/micro-scale.Researchers had found that traditional macroscopic continuous models were inadequate for describing and explaining the mass transfer behavior at gas-liquid interfaces with nano-/micro-scale,making the development of new models applicable to these scales significantly important.This article reviewed recent progress on the mass transfer behavior at gas-liquid interfaces with nano-/micro-scale,specifically including:(1)nano and micro structure of gas-liquid interface and molecular enrichment phenomena;(2)interfacial instability phenomena caused by surface tension,surface tension gradients,and density differences;(3)existing theories of gas-liquid interfacial mass transfer and progress in this area at the nano and micro scales.
