主要研究利用液相色谱原子荧光联用技术对水中不同价态的金属锑进行检测，并用GUM 方法和Top‐Down技术的控制图法分别对其测量不确定度进行评定。实验结果发现GUM 方法步骤较为繁琐，对分析不确定度的来源分析容易造成遗漏或重复，对于某些不确定度来源可能难以定量。控制图法基于实验室质控工作数据，在确保数据具有正态性和独立性的前提下，评定不确定度能有效反应实验室长期质控状态，在水质检测领域的不确定度评定中更为适用。

The different valence antimony in water was determined by high performance liquid chroma‐tography with atomic fluorescence and the measured uncertainty was evaluated by the GUM method and the control chart method based on top‐down technique respectively. The experimental results showed that GUM method was more complicated , and it might cause omission or duplication , and quantify some sources of uncertainty difficultly. The data of the control chart method based on top‐down technique was from laboratory quality control work ,with assuring data normality and independence ,the calculation of uncertainty could effectively display laboratory quality control state in long‐term. It would take more obvi‐ous advantages of uncertainty evaluation in w ater quality test field.
