摘　　要：最近十几年来,随着现代微/纳米测试以及分子动力学模拟技术的出现和发展,流体流动的边界滑移问题研究获得了突飞猛进的发展.边界滑移相关研究大体可分为3个方面:实验、分子动力学模拟和理论数值分析,前两者主要以发现边界滑移现象、探索边界滑移的产生机理以及各因素对边界滑移的影响规律为主要研究目的,向后者主要研究边界滑移的物理模型、相关问题的计算方法以及边界滑移对流体系统流体动力学行为的影响.本文首先简要回顾了液体流动的边界滑移及其相关问题的早期研究历史,随后对边界滑移问题的研究现状进行了综述,最后展望了该领域今后的研究重点及其应用前景.During recent years, great progress has been made in the study of boundary slip problem of fluid flow with the development of micro/nano test technologies and molecular-dynamic simulation （MDS） technology. In general, boundary slip problem is studied through experimental observation, MDS, and numerical analysis. Experiments and MDS are usually used for discovering the boundary slip phenomena, revealing the physical mechanism that triggers boundary slip, and investigating the effects of various factors. Numerical analysis is used to study the appropriate constitute model of boundary slip, computational algorithm, and the impact of boundary slip on the hydrodynamics of the flow. In this paper, we briefly review some early research on the boundary slip problem, then review recent work, and end with a discussion of future work and prospects of the boundary slip application.
