摘要：

目前在辐射温度计和热像仪温度的定标上,都缺乏对用于定标黑体的有效发射率的定标,而黑体炉在温度测量及量值传递中处于重要的地位。为了避免温度计量量值的混乱,克服由于没有统一方法及设备造成确定黑体炉有效发射率值不统一的问题,需要尽快明确黑体炉有效发射率定标的问题,以达到规范黑体炉有效发射率确定的目的,确保温度量值的准确可靠。

Abstract: Blackbody furnace is essential equipment in temperature measurement.In non-contact temperature measurement, it is a temperature measurement standard device in instrument calibration.At the same time, it is a standard temperature source.Blackbody furnace plays a pivotal role in our country's transfer radiation thermometer diagram.The value ε of the effective emissivity of blackbody cavity radiation is an important parameter in describing the quality of blackbody furnace.But there is not associated calibration method, which leads to resulting confusion in the temperature measurement.Thus blackbody must be traced to the source of benchmark blackbody.
