摘　　要：以气相色谱法测定黄瓜样品中毒死蜱的残留量,通过分析检测过程和检测结果,对检测方法进行不确定度评估,分别计算标准曲线、称量过程及样品处理等各不确定度结果,并对各分量不确定度进行合成。结果表明,当黄瓜中毒死蜱含量为1.8592 mg/kg,k=2(95%置信度)时,其含量区间为X=(1.8592±0.2589)mg/kg。试验为改善检测农产品中毒死蜱残留检测方法提供理论支持。The residue of chlorpyrifos in cucumber was determined by gas chromatography,the detection process and results were analyzed,the uncertainty of the detection method was evaluated,and the uncertainty results of the standard curve,weighing process and sample processing were calculated and summarized.The results showed that when the content of chlorpyrifos in cucumber was 1.8592 mg/kg,k=2(95%confidence),the content range was X=(1.8592±0.2589)mg/kg.The experiment provided theoretical support for improving the detection method of chlorpyrifos residues in agricultural products.
