摘要
对表面粗糙度比较样决Ra测量结果的合成不确定度和扩展不确定度的分析与计算进行了阐述。该方法对表面粗糙度测量结果的不确定度评定有一定参考价值。
The conception of the meaning of uncertainty of a measurement is introduced. Analyzing and calculating of composition and expantion uncertainty for surface roughness comparison specimens results of measurements are explained. The estimation method of uncertainty in this paper, are also useful for other measuring cases.
