摘　　要：文章基于气象新型蒸发测量系统对蒸发传感器现场校准结果进行不确定度分析。依据《自动气象站新型蒸发现场校准方法》和JJF1059.1-2012《规程测量不确定度评定与表示》的要求,对蒸发校准点分别进行10次重复试验,对合并样本标准偏差进行A类不确定度评定。分析B类不确定度来源,进行B类不确定度评定。最后将两类不确定度进行合成,得到扩展不确定度。新型蒸发传感器校准结果的不确定分析对于其可信度评定具有很好的参考价值。The article analyzes the uncertainty of on-site calibration results of evaporation sensors based on a new meteorological evaporation measurement system.According to the requirements of New Evaporation Filed Calibration Method for Automatic Meteorological Station and JJF1059.1-2012 Evaluation and Expression of Uncertaintv in Measurement,10 repeated tests were conducted on the evaporation calibration points,and the combined sample standard deviation was evaluated for type A uncertainty.Analyze the sources of type B uncertainty and conduct an assessment of type B uncertainty.Finally,the two types of uncertainties are combined to obtain the extended uncertainty.The uncertainty analysis of the calibration results of the new evaporative sensor has good reference value for its credibility evaluation.
