The EML technique has big advantages for easily keeping large undercooled due to containerless situations. When we measure using this technique the density of liquid metals or molten semiconductors, the volume of levitated droplet-samples must be precisely observed from their shapes. In conventional methods, volume of the droplets obtained by averaging of few hundred images taken by high-speed camera, but large error values appear in temperature dependence data due to the asymmetry of surface oscillation of electromagnetically levitated liquid droplets. In this study, we propose new method to obtain accurate density of high temperature liquid by using the analytical technique of surface oscillations. We confirmed that this technique is useful for precise measurement of high temperature melt density combined with the static magnetic field experiments., 形態: カラー図版あり, 共催: 日本学術会議, Physical characteristics: Original contains color illustrations, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113048}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {電磁浮遊法による高温融体密度計測の液滴表面振動解析による高精度化}, volume = {22}, year = {2006} }
