摘　　要：基于灰色系统理论给出残余误差的定义,提出求解测量结果实验标准差的新方法,以此来评定测量不确定度。评定结果表明,该方法简单易行,与采用贝塞尔公式得到的结果相对误差较小,具有相当的精度和较强的实用性,尤其对测量数据较少或统计规律未知的测量过程尤为实用。Based on gray system theory, residual error definition is introduced; a new method is provided to give standard deviation of measurement results and evaluate A type standard uncertainty. Evaluation results show that it is very close to result by Bessel formula; the method is simple, precise and useful. It is especially practical to the measurement with few data or difficult to follow the statistic regulation.
