| 摘 要： | 采用气相色谱法测定果汁饮料中甜蜜素的含量，对测定结果的不确定度进行了分析，对各不确定度分量进行了评定和量化，计算了合成标准不确定度和扩展不确定度。不确定度主要来自量器校准和标准曲线引入的不确定度。果汁饮料中甜蜜素的含量结果表示为（0．350±0．023）g／kg，k=2。

| Abstract: | Sodium cyclamate in juice beverages was determined by gas chromatography,and the uncertainty of determination result was analysed and quantified.It was found that the uncertainty mainly derived from the uncertainty of measuring vessel calibration and calibration curve.The determination result was(0.350±0.023)g/kg,k=2. |
