| 摘 要： | 以气相色谱法测定某空气样品中丙酮的浓度,并分析评定了测量过程中5个部分的不确定度。该样品空气中丙酮的浓度为0.74 mg/m3,扩展不确定度为U=0.04 mg/m3（k=2）,结果可表示为：（0.74±0.04）mg/m3。此方法可用于测定空气中丙酮含量的不确定度评价,更有助于准确地表述测量结果。

| Abstract: | The concentration of acetone in the air sample was measured by Gas Chromatography.The uncertainty of five parts of the measurement process was analyzed and evaluated.The concentration of acetone in the air sample was 0.74 mg/m3,extended uncertainty was 0.04 mg/m3（k=2）,and the result of measuring acetone in the air sample was（0.74±0.04） mg/m3.The established method was applicable to the uncertainty analysis for the determination of acetone in air.It was favourable to record measurements more accurately. |
