利用几种陶瓷的努氏硬度与载荷的关系实验数据，检验了Li和Bradt提出的比例试件电阻(PSR)模型在较宽载荷范围内观察到的压痕尺寸效应(ISE)的适用性。PSR模型被证明不足以描述实验数据，并在考虑了加工引起的残余应力表面对硬度测量的影响的基础上进行了修正。(C)2001 Elsevier Science B.V.保留所有权利。
Utilizing experimental data of the Knoop hardness versus applied load for several ceramics, the applicability of the proportional specimen resistance (PSR) model proposed by Li and Bradt to describing the indentation size effect (ISE) observed in a relatively wide range of applied load was examined. The PSR model was proven to be insufficient for representing the experimental data and was modified based on the consideration of the effect of machining-induced residually stressed surface on the hardness measurements.
