摘要
针对行波磁场的应用评述了其近几年理论和实验的研究进展,包括行波磁场原理、行波磁场发生器的设计、行波磁场在晶体生长过程中的效应。论述了在晶体生长过程中行波磁场引起的子午线流对导电熔体的稳定性、生长界面形貌和溶质分布的影响,指出了该领域当前研究存在的问题并展望了其发展趋势。
Based on the current studies mainly involved in the principle of a traveling magnetic field, the designof a traveling magnetic field generator and the effects of a traveling magnetic field in crystal growth, the development of the researches on the theoretical and experimental results on the traveling magnetic field applications is reviewed. In crystal growth, the effects of a symmetric meridional flow induced by a traveling magnetic field on the stability, growth interface shape and solute distribution of the conducting melt are discussed. The existing problem nowadays and the development trends in this field are pointed out.
