圆柱形半透明介质腔的视在发射率

Apparent Emittance of Cylindrical Enclosures Filled with a Semitransparent Medium

从比耳－朗伯吸收定律出发，经过分析推导，得到了圆柱形半透明介质腔的单色视在发射率的计算式。对材料组成相同但长径比不同的腔体进行了计算，并将结果与实验进行比较，发现计算结果与实验数据比较吻合。

Through analysis and deduction,this paper obtains the calculating formulas of the monochromatic apparent emittance of cylindrical enclosures filled with a semitransparent medium from the Beer Lambort’s Law.Thecalculations of all sizes of enclosures filled with a fixed medium are also in agreement with the experimental results.
