一、概论人造黑体是红外辐射的标准源,对它的研究是红外辐射的基本课题之一。此外,人造黑体在校验光学(或光电)高温计和在测量材料的热辐射系数等工作中,也是必不可少的。因此,许多国家都很重视人造黑体的黑度系数估算,并相继提出 I. Introduction Artificial blackbody is the standard source of infrared radiation, its research is one of the basic topics of infrared radiation. In addition, artificial black body in the verification of optical (or photoelectric) pyrometer and measurement of material thermal emissivity and other work is also essential. Therefore, many countries attach great importance to the estimation of blackness coefficient of artificial black body, and have put forward one after another
