摘要
分析了全自动色差计测定龙泉青瓷色差引起不确定度的各分量来源,对其不确定度进行了合理的评估。结果表明,取置信概率p=95%,包含因子k=2,龙泉青瓷色度刺激值扩展不确定度U(Y)为2.12,色品坐标扩展不确定度U(x)、U(y)分别为0.0022、0.0022。评定结果表明,仪器示值误差引入的不确定度贡献最大。
The main uncertainties sources of colorimetry in longquan celadon were analyzed by automatic Color Difference Meter.The degree of uncertainties were reasonably evaluated.The results showed that when the confidence level(p)is 95%,the including factor(k)is two,the expanded uncertainty of stimulus value U(Y)is 2.12,the chromaticity coordinates(x,y)were 0.0022,0.0022 respectively.The evaluation results suggested that the uncertainty mainly comes from the instrument indication error.
