摘　　要：基于证据理论,针对测量中的非精确性数据提出了一种不确定度评定方法。该方法首先计算非精确性数据的不确定性,包括不具体性和随机性,建立了不确定性与不确定度的关系公式,利用关系公式和不确定性计算不确定度。该评定方法同时适用于精确性和非精确性测量数据,是传统香农熵评定方法的广义形式,给出实例验证了其有效性。Based on D-S theory, a new method is presented to evaluate the measurement uncertainty of imprecise data. According the method, the total uncertainty including nonspecificity and stochasticity is firstly calculated, and then a formula that relates the total uncertainty to measurement uncertainty is established. Finally measurement uncertainty is got with the formula and total uncertainty. The method can be applied to both precise data and imprecise data. Examples are demonstrated to show its efficiency.
