摘要
面黑体的积分发射率是面黑体的重要辐射特性.提出了一种近似计算方法.计算步骤如下:一、计算子腔有效发射率分布.二、根据子腔有效发射率分布,计算子腔对子腔口的有效发射率分布.三、计算蜂窝面黑体的积分发射率.应用该方法,计算了作者所研制的蜂窝面黑体的积分发射率并对计算结果进行了分析,分析结果表明该方法是切实可行的.
The method takes the following steps: (1)to calculate the distribution of the effective emissivity of the subcavity, (2)to calculate the distribution to subcavity opening of the effective emissivity of the subcavity l and (3)to calculate the integrated emissivity of a multi -celled large-area blackbody. The analysis shows that the method is feasible and satisfactory.
