摘　　要：在实际计量测试过程中会遇到超高温的设备,受标准器或者整个行业发展的限制无法直接检测。针对上述问题,利用灰色系统理论,根据少量的温度测量点建立起GM(1,1)模型,通过GM(1,1)计算出的理论值和仪器的显示值对比来评价被检设备的误差大小。试验证明利用GM(1,1)模型能够评价无法直接检测出的误差大小,为今后工作中出现难以计量的设备检测提供了一种思路。In the actual measurement test process,ultra-high temperature equipment will be encountered,which cannot be directly detected due to the limitations of the standard or the entire industry.In view of the above problems,this paper uses the gray system theory to establish the GM(1,1)model according to a small number of temperature measurement points and evaluates the error size of the tested equipment by comparing the theoretical value calculated by GM(1,1)with the display value of the instrument.Experiments show that the GM(1,1)model can be used to evaluate the magnitude of the error that cannot be directly detected,which provides an idea for the occurrence of equipment that is difficult to measure in future work.

关 键 词：GM(1 1) 预测值 误差评估值
