Abstract

In order to study the radiation characteristics of a compound-cavity blackbody, a method for calculating the integrated emissivity is presented in this paper. With this method, firstly, the distribution of the effective emissivity of the sub-cavity of a compound-cavity is calculated; secondly, from the distribution of the effective emissivity, the integrated emissivity of the walls of the sub-cavity to the mouth of the sub-cavity can be obtained; and thirdly, the integrated emissivity of a compound-cavity blackbody is calculated. Employing this method, we calculated the integrated emissivity of a compound-cavity blackbody and analysed the results. The analysis shows that this method is feasable and satisfactory.
