摘要：

The self-diffusion coefficient, D-S in liquid Sri was measured by a long capillary method in the microgravity environment of the space shuttle, and the validity of a microgravity effect was confirmed for the measurements of diffusion in melts with high melting temperatures. The data of this D-S under microgravity were well reproduced by calculations, particularly in the case closely related to liquid structures. A systematic microgravity experiment is required to obtain further insight and to develop a model for diffusion in group IVB liquids. (C) 2002 Elsevier Science B.V. All rights reserved.
