摘要
文中从建立热解析-气相色谱法测定室内燃香空气中TVOC含量不确定度的数学模型,分析和评估测定过程中引入各分量的不确定度来源,并计算合成相对标准不确定度和扩展不确定度结果。
A mathematical model of the uncertainty evaluation for detecting the content of TVOC from incense combustion air by Thermal Desorption-Gas Chromatography was established in this paper. The sources of uncertainty from the influential factors in the measurement process were analyzed and estimated. The relative standard uncertainty and the extended uncertainty were calculated.
