摘　　要：　研制了一种专门用于红外耳温计分度的双孔黑体空腔,并用研制的黑体空腔对红外耳温计在37℃和41℃进行了分度实验.实验结果表明,此黑体空腔的空腔发射率已达到0.999,完全能作为红外耳温计分度的标准辐射源.最后对实验结果进行了不确定度的评定.A dual\|cavity blackbody has been manufactured and its cavity emissivity is calculated . The infrared tympanic thermometers are calibrated against the blackbody at 37 ℃ and 41 ℃. The result shows that the blackbody emissivity is over 0.999 and can been taken as a radiation standard for calibrating the infrared tympanic thermometers. At last the uncertainty are evaluated for the infrared tympanic thermometer calibration.
