Spectroscopic Study of the Emission from Solids （1st report） -Monochromatic emittance and total emittance of the smooth and the rough surfaces of metals- 固休ふく射の分光研究 （第１報） -金属半面および粗面の単色ふく射率と全ふく射率- 金山, 公夫 31880 馬場, 弘 31881 application/pdf The monochromatic emittances of smooth and rough surfaces of aluminum and brass were measured directly，at 200℃ specimen temp., whose surfaces were scratched by the sand papers of various grain size. The rolled surfaces of metals on the market were used for the smooth surfaces. At the same time, the total emittances on these surfaces were measured by the vacuum radiometer of thermo-couple type. Agreement was obtained between the total emittance calculated from definite integral of the monochromatic emittance and the total emittance measured directly. departmental bulletin paper 北見工業大学 1970-12 application/pdf 北見工業大学研究報告 5 2 669 677 https://kitami-it.repo.nii.ac.jp/record/6246/files/2-5-2.pdf https://kitami-it.repo.nii.ac.jp/records/6246 jpn
