| 摘 要： | 对直接辐射表校准结果的不确定度进行分析,为直接辐射表测量数据的质量控制提供可靠的依据。通过大量试验以及数学模型的建立,分析并列出对测量结果有明显影响的不确定度来源,对各标准不确定度分量进行定量评定,得到直接辐射表校准结果的扩展不确定度为1.6%（置信概率P=95%;包含因子k=1.96）。结果表明直接辐射表测量结果的不确定度由多种因素引起,它取决于校准方法、校准设备、校准环境条件等。

| Abstract: | It is important to analyze the uncertainty of calibration results of the pyrheliometer.The analysis results establish the reliable basis for the quality control of the pyrheliometer measurement.The mathematical model is established and the sources of uncertainty are pointed out which obviously infect the measurement results.The uncertainty components are evaluated quantitatively and the expand uncertainty of the results of the pyrheliometer are 1.6% (confidence probability P=95%;coverage factor k=1.96).The ... |
