摘　　要：在红外光谱仪的定标中 ,为了减小误差 ,可以选取多温度点的测量来进行定标 ;此外对于测量较弱红外辐射的光谱仪 ,环境温度对定标结果也有不可忽视的影响 .本文主要讨论利用测量多温度点的标准黑体进行定标的方法。In calibration of a infrared spectrum radiometer, we calibrate an infrared radiometer by measuring on various temperatures of the blackbody in order to reduce error. For the radiometer measuring weak radiation, the background temperature has unavoidable effect on calibration. The methods of calibration by measuring the standard blackbody at different temperature was discussed. The experimentation results were analysed, and the effect of the background temperature on the calibration result was given.
