摘　　要：[目的]评定连续流动分析法测定卷烟主流烟气中的氰化氢含量的测量不确定度。[方法]试验分析了测定过程中不确定度来源,建立了数学模型,并计算了各标准不确定度分量、合成标准不确定度、扩展不确定度。[结果]试验得出,连续流动分析法测定卷烟主流烟气中的氰化氢含量的测量结果的扩展不确定度为7.00μg/支,其中标准溶液校准及稀释过程中引入的不确定度分量最大。[结论]为保证该测定方法检测数据的准确性,应定期对定量移液器校准,严格按规定配制工作曲线。[Objective]The uncertainty in detection of hydrogen cyanide content in mainstream smoke of cigarette by the continuous flow method was evaluated in this paper. [Method]The sources of uncertainty in process of detection were analyzed. The mathematics model was established.The components of standard uncertainty,combined standard and expanded uncertainty were calculated. [Result] The expanded uncertainty was7. 00 μg / cig,the uncertainty of the calibration and dilution of the standard solution is the largest. [Conclusion]In order to ensure the accuracy of the test method,quantitative shift should be regularly calibrated.
