摘　　要：二等标准水银温度计(简称温度计)检定结果的不确定度,直接影响温度量值传递的检定结果。针对我国省级气象计量单位现用的温度计量标准,从温度计的测温原理、检定方法、测量不确定度分量入手,根据JJF1059-1999《测量不确定度评定与表示》规范的分析方法,利用2007年检定数据,对一套温度计的检定结果进行不确定度评定。通过对检定结果的不确定度评定,梳理出一套清晰的分析步骤和科学方法,同时也为省级气象计量部门定期接受技术监督局的计量标准考核,提供误差分析范例。The uncertainty of calibration results for second-class standard mercury thermometers directly influences the delivered results of temperature quantity values. According to the related standards of temperature instruments, the uncertainty of calibration results for a set of standard thermometers is evaluated by the method of JJF1059 1999 （Evaluation and Expression of Uncertainty in Measurement）, on the basis of temperature measuring principles, calibration methods, components of the uncertainty, and the calibration data of the second-class standard mercury thermometers in 2007. Based on the calibration results, a set of error analyzing procedures and methods are devised, which provide an example of error analysis for province-level metrological service.
