测量不确定度的英文表述为:Parameter,associated with the result of a measurement,that charactenzes thedispersion of the values that could reasonably be attributed to the measurand中文表述为:表征合理的赋予被测量值的分散性,与测量结果相联系的参数。它表明测量结果不能肯定的程度,是评定测量水平的指标,判定测量结果的依据 换句话说:是表明测量真值所处的量值范围,其值越大表示越不可靠。其值比较小,表示测量结果准确度越高

The English expression of measurement uncertainty is: Parameter, associated with the result of a measurement, that charactenzes the dispersion of the values ​​that could reasonably be attributed to the measurand The Chinese expression is: Characterization Reasonable Given Dispersibility of Measured Value, Results related parameters. It indicates that the measurement result can not be affirmed. It is an index for measuring the measurement level. The basis for judging the measurement result. In other words, it means that the measurement value lies in the range of values. The larger the value, the less reliable it is. The smaller the value, the higher the accuracy of the measurement
