触针式粗糙度仪的测量不确定度分析及仪器的特性评定

Uncertainty Analysis and Eligibility Evaluation of Stylus Roughness Tester

测量不确定度是对测量结果质量的定量表征,它在一定程度上表示了测量结果的可用性。针对触针式粗糙度仪的校准结果进行测量不确定度分析的论述,并进行了仪器的特性评定。

Uncertainty is the quaintitative performance for measurement quality,it partially presents measurement s availability. This thesis discusses the method of uncertainty analysis based on machine＇s calibration results and evaluates the machine＇ s eligibility according to the results.
