【摘要】 目的为了规范RRK-SR-Ⅱ型定量采样机器人不确定度的评定,使检测结果准确、可靠。方法本文利用定量采样机器人对风管内积尘量进行检测,分析各不确定度分量对测量结果的影响。结果结果显示当平均积尘量为20.0080g/m~2时,其扩展不确定度为1.1064g/m~2(K=2);当平均积尘量为1.1060g/m~2时,其扩展不确定度为0.0977g/m~2(K=2)。结论结果满足相对误差≤20%,相对偏差≤10%的标准,且本研究中的检测方法和计算过程适合于评定其他RRK-SR-Ⅱ型定量采样机器人不确定度。更多还原

【Abstract】 Objective In order to standardize the uncertainty analysis of RRK-SR-Ⅱquantitative sampling robot,which makes the results accurate and reliable.Methods This research detected the dust inside the duct by quantitative sampling robot,aimed to analysis every component effects on the final measurement results.Results The results showed that the expanded uncertainty was 1.1064g/m~2(K=2) when the average dust content of 20.0080g/m~2,the expanded uncertainty was 0.0977g/m~2(K=2) when the average dust content of 1.1060g/m~2.Conclusion The results meet the relative error of≤20%,relative standard deviation of≤10%.And the detection methods and calculation process in this study also suit other RRK-SR-Ⅱquantitative sampling robots uncertainty analysis.更多还原
