【摘要】 结合实验室的实际情况,对连续流动法测定卷烟主流烟气中氢氰酸含量的测量不确定度进行评价,分析了氢氰酸含量检测的影响误差,计算了不确定度分量及合成不确定度,并得出测量结果扩展不确定度为5.47μg/支,为测量结果提供了可信度和可信区间.更多还原

【Abstract】 The uncertainty for determination of hydrogen cyanide in mainstream smoke by the continuous flow method was evaluated.The influence factors on the uncertainty determination of hydrogen cyanide content were analyzed,the component and combined uncertainties were calculated,and the expanded uncertainty was 5.47 μg/cig,providing the credibility and confidence interval for the measurement results.更多还原
