摘　　要：文章介绍了气相色谱法测定海水中滴滴涕含量的不确定度评定方法,分析了测量程序中不确定度的各项来源,对该方法所得分析结果的已识别来源的不确定度影响进行评价,可为实验室在该项检测过程中进一步提高检测数据的可靠性和一致性作参考。In the paper, the gas chromatography method was presented for the evaluation of uncertainty to detennine DDT in sea water. Various sources of uncertainty from the determination procedure were assessed. The influence of the identified uncertainty, of the analytical result was evaluated, and references for thereliability and consistency of the testing data in the laboratory were made.
