摘　　要：叙述了铝合金熔体精炼理论和工艺方面某些有说服力的研究成果，涉及“临界流速、“污染－净化动态平稳”概念，引出旋转喷吹净化工艺的优越性，提出了净化工艺应遵循的原则，指明了铝熔体中Ａｌ２Ｏ３和Ｈ２之间的相互依存关系。Some brief of convinced study result, as the conception of “Critical vetocity of degassing gas”, “Kinetic Balance of ContaminationRefinement” was showed. Raised the discipline for refinement technology of aluminium alloys and explained the interaction phenomenom of Al_2O_3 with H_2 inside the aluminium melt.
