高功率密度（１０６～１０１０）Ｗ／ｃｍ２脉冲电子束、离子束和激光束与靶物质相互作用产生瞬态高温、高压和烧蚀作用，其过程已被用于材料改性、表面涂复及低维材料研究等广泛领域。重点介绍赝火花（Ｐｓｅｕｄｏｓｐａｒｋ）脉冲粒子束在纳米科技中的应用
High power density (106-1010) W / cm2 pulsed electron beam, ion beam and laser beam interact with target material to produce transient high temperature, high pressure and ablation. The process has been used for material modification, surface coating and Low-dimensional materials research and other fields. The application of Pseudospark pulsed particle beam in nanotechnology is emphasized
