　　中文摘要：鎂的性質(zhì)很活潑，在熔煉過程中會產(chǎn)生大量夾雜和氣體，大大降低了其合金性能。介紹了合金中夾雜和氣體的種類及來源，綜述了目前國內(nèi)外鎂合金凈化技術(shù)的研究進展，如吹氣法、熔劑凈化法、過濾法、稀土凈化法、電磁凈化法等，并討論了其機理，展望了凈化技術(shù)的未來發(fā)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.
