根据测量不确定度评估与表示理论,从HR-7801干膜润滑涂层厚度重复性测量、测量仪器、标准箔片、数据修约等方面分析了测量不确定度来源,以及测量不确定度在试验结果中的表示方法,推算了HR-7801干膜润滑涂层厚度测量不确定度,得出了HR-7801干膜润滑涂层厚度测量结果的合成不确定度。
According to the theory of measurement uncertainty and representation theory, the sources of measurement uncertainty are analyzed from the aspects of repeatability measurement of thickness of HR-7801 dry-film lubrication coating, measuring instruments, standard foils and data revisions, and the measurement uncertainty The results show that the uncertainty of HR-7801 dry-film lubrication coating thickness measurement is deduced. The synthetic uncertainty of HR-7801 dry-film lubrication coating thickness measurement results is obtained.
