摘　　要：本文以测定甘蔗中速灭威残留量为例,评定了利用高效液相色谱串联质谱法(HPLC-MS/MS)测定结果的不确定度。分析影响测定结果不确定度的因素,通过建立数学模型对各个不确定度分量进行计算,最终给出该方法测定结果的合成标准不确定度和扩展不确定度。The uncertainty of measurement for tsumacide pesticide residues in sugarcane by HPLC-MS/MS was evaluated. The mathematical model of measurement was set up. The different parts of uncertainty were analyzed, and the combined standard uncertainty and the expanded uncertainty of measurement results were calculated.
