note = {application/pdf, The exact formula，which is developed by Fresnel from the electromagnetic theory to explain the emissive characteristics of some metallic flat surfaces，is a complicated expression and it is a difficult problem to analyze the apparent directional emittance of metallic random rough surfaces by applying directly the exact formula to these surfaces. In his report，therefore，two approximate formulas of the directional emissivity introduced by Schmidt and others from Fresnel's formula，one simple formula used already in the published papers and the other a more complicated formula，are adopted to analyze the apparent directional emittances of the v-groove rough surface，the circular arc groove rough surface and the random rough surface of metals. The calculated values from both formulas are comPared with each other and are shown in the graphic expressions.},
