采用零集分形和功率谱分形分析方法，在微/纳米范围内分析了铝带的单压缩粘接性能。利用原子力显微镜（AFM）估计了分形维数。发现附着力、刀具表面和试样表面具有分形结构。对附着力、刀具和试样表面的各种分形维数进行了比较和讨论。当刀具表面粗糙度相同时，总附着面积的比值取决于分形维数。虽然原子力显微镜难以区分粘附颗粒和刀具表面，但功率谱维度有可能区分粘附颗粒和刀具表面。最后，提出了一种纳米尺度表面结构的计算机模拟方法，获得了令人满意的图像。
Adhesion properties in simple compression of aluminum strips are analyzed in the micro/nanometer range by employing the zeroset and power spectrum fractal analyses. An atomic force microscope (AFM) is used to estimate the fractal dimensions. It is found that the adhesion and tool and specimen surfaces have fractal structure. Various fractal dimensions obtained for the adhesion and tool and specimen surfaces are compared to each other and discussed. When the surface roughness of tool is same, the ratio of the total adhesion area depends on the fractal dimension. Though the AFM apparatus is difficult to distinguish the adhesion particles from the tool surface, the power spectrum dimension has possibility of distinguishing the adhesion particles from the tool surface. Finally, a method for computer simulation of the nanometer scale surface structure is presented, and satisfactory images are constructed.
