Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, The thermal conductivity of powder materials, such as regolith and dust layer, is important properties for understand the thermal evolutions and conditions of solid bodies. We measured the effective thermal conductivity of glass beads of several sizes from -25 to 50 degC under vacuum conditions. The experimental results indicated that both solid and radiative conductivity increase with increasing the particle size, which is not consistent with a previous study. Considering the mechanism of these trends will have important meaning., 形態: カラー図版あり, 形態: CD-ROM1枚, Physical characteristics: Original contains color illustrations, Note: One CD-ROM, 資料番号: AA0065390022}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {Experimental Consideration of Thermal Properties of Soils on Solid Bodies}, volume = {44}, year = {2011} }
