摘　　要：疏水微形貌表面减阻是一种新型仿生减阻方法,也是国内外减阻研究领域的热点之一。该文在分析天然及人造疏水微形貌表面界面一般特性的基础上,从壁面滑移流动、表面微形貌等角度总结了国内外疏水微形貌表面减阻理论研究的最新成果,然后分类给出了近年来疏水微形貌表面减阻微观及宏观试验的研究进展,最后分析了疏水微形貌表面可能的减阻机理及目前存在的技术问题。Hydrophobic micro-structured surfaces drag reduction is a novel method in the study of the bioinspired drag reduction, which became a hot research topic in the last decade. Based on the properties of artificial and inartificial hydrophobic micro-structured surfaces, the recent development about drag reduction on hydrophobie micro-structured surfaces is reviewed generally from slip flow on the wall and micro- cosmic structures above the surface. Then the drag reduction experimental advancement about hydrophobic micro-structured surfaces is summarized in two parts： microcosmic tests and macroscopical tests. Finally, the potential drag reduction mechanism on the hydrophobie micro-structured surfaces and the shortage of recent research are analyzed.
