| 摘 要： | 采用分层建模方法建立了气相色谱法测定食用菌中毒死蜱含量不确定度评定的数学模型,分析了影响测量标准不确定度结果的各个因素,采用最小二乘法对外标曲线拟合的不确定度进行了评定。计算被测量的合成不确定度和扩展不确定度分别为：0.0286、0.239±0.014 mg/Kg。

| Abstract: | This paper establishes mathematical model of uncertainty evaluate of ehlorpyrifos in mushroom by gas chromatogra- phy. Uncertainty are analyzed to compose steds for whole determinational fitting is evaluated with the least square method. The combined standard uncertainty and expanded uncertainty are calculated, which are 0. 0286,0. 239±0. 014 mg/kg, respectively. |
