采用顶空-气相色谱法对水中三氯甲烷、一溴二氯甲烷、二溴一氯甲烷和三溴甲烷4种卤代烃测定结果的不确定度进行了评定，并对测量重复性、标准差、标准溶液浓度等影响测量结果的不确定度分量进行了分析和量化。当水中三氯甲烷、一溴二氯甲烷、二溴一氯甲烷和三溴甲烷测定结果为18．58、12．74、21．00、18．43μg/L时，其扩展不确定度分别为3．32、2．96、3．14、3．00μg／L（k=2）。

The uncertainty of measurement was evaluated for the determination of halohydrocarbon in water, including chloroform, bromodichloromethane, dibromochloromethane and bromoform, by the method of headspace - gas chromatography. The uncertainty components of the measurement results, including repeatability of measurement results, standard deviation, and the concentration of standard solution were analyzd and quantified. When the determination results of chloroform, , dibromochloromethane, bromoform in water were 18.58,12.74,21.00,18.43 μg/L, the expanded uncertainty of which were 3.32, 2.96, 3.14, 3.00 μg/L（k =2） respectively.
