摘　　要：通过对韧性膜/韧性基底体系的Berkovich压入过程进行量纲分析,得到了压入法的加卸载参数和韧性膜/基底的力学参数之间的无量纲函数关系,为建立压痕法表征韧性薄膜力学性能的模型奠定基础.A dimensional analysis was carried out about the process of Berkovich-indentation on a ductile film/substrate system. The corresponding dimensionless relationship between the loading/unloading parameters and the mechanical parameters of ductile film/substrate was obtained. This lays the foundation for the establishment of the model which can characterize the mechanical properties of ductile thin films by the indentation method.
