Abstract

Similarities between various cavity emissivity theories have been examined. It is shown here that, for the special case of the (isothermal) diffuse spherical cavity, the closed form emissivity expressions obtainable from the work of Gouffé, DeVos, and Sparrow and Jonsson agree exactly. Further, this result is not limited by the size of the opening in the cavity.

摘要

已对各种腔体发射率理论之间的相似性进行了研究。结果表明，对于（等温）漫射球形腔体的特殊情况，从古费、德沃斯以及斯帕罗和琼森的研究成果中得出的封闭形式发射率表达式完全一致。此外，这一结果不受腔体开口尺寸的限制。
