摘　　要：测量不确定度是对测量结果质量的定量表征,测量结果的可用性很大程度上取决于其不确定度的大小。用万能测长仪测量内尺寸作为机械产品测量中常见的测量任务,其测量不确定度的评定是非常必要的。然而对于长期从事机械产品检验的人员来讲,只给出了测量结果 ,而没有给出测量不确定度,这便阻碍了测量数据的质量在国际间得到评价和认可的机会。就此问题,本文详细阐述了用万能测长仪测量内尺寸的测量不确定度分析过程。Uncertainty of measurement is a quantitative characterization of the quality of measurement result, the availability of measurement depends largely on the size of the uncertainty. Universal length measuring gauge is used to measure the size as a common measurement task in the mechanical products measurement, the measurement uncertainty assessment is very necessary. However, for personnel engaged in mechanical products inspection for a long time, only the measured results are given, and no uncertainty of measurement is given, it hinders the quality of the measurement data of internationally recognition by evaluation and opportunities. On this issue, this paper expounds the universal length measuring gauge is used to measure inside dimension of the measurement uncertainty analysis.
