本文应用计算黑体空腔有效发射率分布的新方法——矩形区域近似法.计算了带盖锥柱形黑体空腔等温和不等温分布时,腔内的单波段有效发射率εa(λ,To,X)分布,并且同 Bedford’s 方法的计算结果进行了比较,比较结果看出两者是一致的。这证明了矩形区域近似法是一种精确计算法,而且矩形区域近似法在计算中避开奇点的处理问题,从而使问题充分简化,且计算时间少,占机内存容量小,编制和调试程序容易.
In this paper, a new method of calculating the effective emissivity distribution of blackbody cavity-rectangular area approximation is applied.The effective emissivity of single-band εa (λ, To , X) distribution, and compared with the results of Bedford’s method, the comparison shows that the two are consistent. This proves that the rectangular area approximation method is an accurate calculation method, and the rectangular area approximation method avoids the singularity problem in the calculation, so that the problem is simplified sufficiently, and the calculation time is small, the memory capacity of the machine is small, and the preparation and debugging The program is easy.
