摘　　要：简要地介绍了近几年来国外等离子技术的开发研究情况和发展现状。在过去几年里，等离子技术中最显著的变革，是用石墨燃炬代替铜燃炬和钨燃炬，石黑燃炬较水冷金属燃炬更安全，并且减少了冷却水的损耗和维护燃炬的费用，使石墨燃炬的工作成本低于其它燃炬。此外，由于等离子技术能够提供充分燃烧和高温反应，因此，等离子技术的应用及其各种工艺流程也得到不断发展。This paper briefly described the present condition and development of plasma technology abroad in the recent years.The most prominent change in the technology uptodate is the substitution of graphite fame torch for the copper flame torch and tungsten flametorch because the former is safer and can reduce consumption of thecooling water and maintenance cost There is an uninterrupted progress in the plasma technology and process flow abroad since it can provide sufficient combustion and high temperature reaction.
