| 摘 要： | 采用国际通用的方法分析探讨了东海近海水质总汞测定中不确定度的影响因素。其中，考虑到海洋环境监测的一些特殊性。在建立评定不确定度分量的数学模型时，引入了重复性实验校正因子f，并根据2002-2004年东海区海洋环境监测中的内拉质量数据（原始平行样测定）资料以A类方式评定量化重复性实验校正因子f的不确定度；同时，以A类或B类的方式对近海水质总汞测定中的其它各个不确定度分量进行了评定。结果表明，重复性实验校正因子f是近海水质总汞测定中不确定度的主要来源；东海近海水质总汞测定中的相对合成标准不确定度约为0．16。

| Abstract: | In the paper, the factors that influence the uncertainty of mercury measurement in offshore water in East China Sea were analyzed by using the universal method. In consideration on specific measurement environment, the repetitive correction factor f was introduced in establishing the model to assess the components of uncertainty. On the ground of the internal control data of parallel sampling in environmental monitoring from 2002 to 2004, type A was used to assess the uncertainty of the repetitive correction factor f, type A and type B were used to assess the other components of uncertainty in mercury measurement. The resuits showed that the main effective factor of uncertainty of mercury measurement was the repetitive correction factor f, and the relative combined standard uncertainty mercury in offshore water in East China Sea was about 0.16. |
