Infrared radiation thermometer (one of the typical cases of infrad system) is calibrated by standard radiation thermometer (λ=0 65 μm,0 9 μm) or standard contact thermometer on the calibrator blackbody furnaces. The formula for brightness temperature deviation,which is caused only by different working wavelengths of the standard radiation thermometer and the calibrated thermometer,is built in the article. It suggests the ununiform temperature factor almost has nothing to do with the wavelaength,the brightness temperature deviation is decreased greatly,i.e.,the calibration precision by the stardard radiation thermometer is much higher than that by the standard contact thermometer. Some typical temperature distribution of blackbody cavities are shown. And the tendency of brightness temperature deviation between the standard and calibrated radiation thermometer,which is just because of different working wavelengths,is discussed,too.

建立了被检辐射温度计和标准辐射温度计只因两者工作波长不同而产生的亮度温度差(精度)的理论公式.此公式内涵表明了由于黑体空腔总精度的不等温分量几乎与波长无关,所以大幅度地降低了上述亮度温度差的差值,即与标准接触式温度计相比大大提高了红外辐射温度计的标定精度.本文还列举了几种典型黑体空腔温度分布的例子,给出了标准与被检温度计因工作波长不同而产生的亮度温度差的走向
