Abstract A novel method using grey theory to characterize the measurement uncertainty is proposed.The method permits an accurate est imat ion of the uncertainty under the condit ions that the measurement number is small and the probability distribut ion unclear. The feasibility of the method is validated by pract ical examples.

Key words： measurement uncertainty grey theory accumulation generation estimation

测量不确定度的灰评定

提出以灰色系统理论为基础评定测量不确定度的一种新方法。通过理论分析与测量实例的评定表明，它不仅对测量的样本量和分布类型没有要求，而且具有相当的计算精度，对统计成非统计测量不确定度的评定均为适用。
