| 摘 要： | 通过气相色谱法和气相色谱-质谱法测定茶叶中的联苯菊酯，对测定过程中可能引入的不确定度进行了分析和评定。根据JJF 1059-1999《测量不确定度评定与表示》中有关规定，建立了不确定度评定的数学模型，对各分量在构成合成不确定度时的影响率进行分析，得出不确定度控制的关键在于控制好样品的前处理和标准曲线。

| Abstract: | The possible uncertainties in the determination of bifenthrin in tea by gas chromatography (GC) and gas
chromatography-mass spectrometry (GC-MS) were analyzed and evaluated. According to Evaluation and Expression
of Uncertainty in Measurement (JJF 1059-1999), a mathematical model of uncertainty was established. Based on the
contribution ratio of each uncertainty component to the synthetic uncertainty, the key uncertainties resulted from sample
pretreatment and calibration curve preparation. |
