Popis:	Shear cell method is one of the most advanced experimental techniques to measure diffusion coefficients in liquids. In order to measure the diffusion coefficient more accurately, error factors of this method were studied. The shearing convection in the shear cell method is one of the major error factors of the measurement of diffusion coefficient. To clarify the effect of shearing convection on diffusion coefficient, the measurement of diffusion coefficient of Au in Ag melt was carried out at temperatures of 1,300 K and 1,500 K with the variation of diffusion time. The time dependence of Au diffusion coefficient in Ag melt was obtained and the feature of experimental error arising from the shearing convection was clarified. 資料番号: AA0048709006 レポート番号: JAXA-RR-04-044E
