 note = {application/pdf, Apparent directional emissivites on the opening of V-grooves were calculated, in two cases of specular reflection and diffuse reflection at inner surface of the groove, taking accounts of angles of emission, incidence and reflection, and numbers of reflections. The calculations are based upon the following assumptions : That specular surface has the monochromatic emittance derived from the electromagnetic theory and that diffuse surface has the emittance following Lambert’s law. At the same time, the experiment on the aluminum rough surface of V-grooves was carried out in the case of specular reflection, and the fine agreement was obtained between calculated and experimental results},
