摘　　要：主要介绍分形这一几何方法在材料表界面研究中的应用。通过对国内外文献及资料的查阅了解,分别介绍了材料表界面分形维数的计算测定方法以及分形理论在材料表界面领域中的研究现状。对分维计算方法如网格法、小岛法和实验测定方法(吸附法)等做了详细的分析,对分形在材料表界面上的应用前景也进行了展望,分析了分形理论在表界面应用研究中的可行性。Some basic theory of fractal and the application in the surface and interface of materials are mainly introduced in this paper. On the basis of information about the fractal application in the native and foreign countries, the calculation methods of fractal dimension and the research actuality about the fractal theory which apply in the surface and interface of materials are introduced. Also the calculation methods of fractal dimension such as gridding, little islands and the experiment methods of mensuration （absorption） are analyzed in detail. At the same time, the prospects of application are forecasted and the feasibility of the application is also analysed.
