在线黑体辐射源的建立及其精度评价

Building of On line Blackbody Sources and Evaluation of Their Precision

在高温的锻造炉内以竖插和横插两种方式建立了几种在线黑体空腔．首次测量了各在线黑体空腔的温度分布，采用作者建立的评价黑体空腔精度的理论公式，评价了各黑体空腔的精度，亦即给出了由于非完全黑体产生的测量误差；并得出了在炉子不同部位安装黑体空腔的规范．

By using up or side tube methods in the forging furnace,a several blackbody cavities have been built. The temperature distribution of the cavities was measured for the first time. The precision grades of the cavities were evaluated by the precision formula developed by the authors.That is,the errors resulted from the non absolute blackbodies were evaluated.Besides the norms of installing blackbody cavities in different areas in a furnace were worked out.
