摘　　要：地面放射性测量模型标准装置在国内属于最高计量标准,无法直接溯源。为确认其系列标准量值处于受控状态,本文采用了定期核查的方法,对核查测量结果通过制作平均值-极差控制图来反映标准量值复现的重复性和稳定性,进而确认标准量值的受控状态。The ground radiometric model standard equipment is the highest grade of measurement standard in China, and it is not traceable directly. To confirm the magnitude of the series of the standards in a controlled state, this paper uses the periodic verification method for verifying the measurement results and makes the average-range control chart to reflect the magnitude of the repeatability and reproducibility of the stability criteria, and then confirms the controlled state of the standard value.
