摘　　要：文章总结了反渗透膜的主要微观指标(包括表面官能团、形貌、表面电位等)以及这些微观指标与宏观性能的关系,表明反渗透膜的宏观性能与其微观指标密切相关,通过调控微观结构可优化反渗透膜分离性能;另外介绍了测试上述微观指标所涉及的常用仪器和方法,并提出当前在微观指标研究中存在的问题,包括结构与性能构效关系研究还不系统、检测方法不统一等;最后探讨了反渗透膜微观指标研究的发展方向。The main microscopic indices（ including surface functional groups,morphology,surface potential,etc.） of reverse osmosis membrane and the relationship between these microscopic indices and macroscopic properties were summarized. The results suggest that there are close relationship between macroscopic performance and microscopic indices. The RO separation performance can be optimized by adjusting the microstructure. Moreover,the corresponding characterization techniques were reviewed,including the introduction of characterization instruments and approaches. Additionally,some problems in microscopic index research were also proposed,for example,the absence of systematic research on structure-performance relationship,no consistent testing method,and so on. It was also discussed the development direction of the microscopic index of reverse osmosis membranes.
