中文摘要：镁的性质很活泼，在熔炼过程中会产生大量夹杂和气体，大大降低了其合金性能。介绍了合金中夹杂和气体的种类及来源，综述了目前国内外镁合金净化技术的研究进展，如吹气法、熔剂净化法、过滤法、稀土净化法、电磁净化法等，并讨论了其机理，展望了净化技术的未来发展。
英文摘要：The property of magnesium is very active, which leads to produce lots of inclusions and harmful gases as well as reduce the properties of the alloy. The variety and origin of the inclusions and gases are introduced. The current development of research on the purification technology in domestic and overseas such as gas purge method, flux purification method, filtering purification method, rare earth purification method, electromagnetic purification method and so on are summarized. Besides, the principle of the methods is investigated. Finally，the development prospect of purification technology of magnesium alloy is presented.
