摘　　要：不确定度是定量说明测量值的一个参数,表明测量值的可信程度,只有量值而没有不确定度的数据是不完整的测量结果。粗糙度的测量结果是通过粗糙度测量仪的示值来反映。因此,粗糙度测量仪本身的测量结果是否可靠、可信,需要通过对测量仪进行校准并对测量仪的示值误差进行校准不确定度评定。本研究对粗糙度测量仪示值误差进行了校准不确定度评定,从而对测量结果的影响因素进行溯源,以便调整测量方法,提高测量结果的准确性。Uncertainty is a parameter that quantitatively explains measured value,which reflects the reliabilityof measured value,and data without uncertainty is incomplete measurement results.The indicating value ofroughness tester reflects the measurement results of roughness.Therefore,we should calibrate the roughnesstester and evaluate the calibration uncertainty of tester’s indication error to ensure the reliability of measurementresults of roughness testers.This paper evaluates the calibration uncertainty of indication error of roughness testerand traces the influence factors of measurement results so that we can adjust measurement method to improve theaccuracy of measurement results.
