摘　　要：人们企图避免和缓解空化带来的危害,但空化瞬间聚集的高能量,可广泛应用于众多工业领域,如清洗、制浆、材料切割、岩石破碎、油井解堵、材料的超细粉碎、改善材料的表面性能、有机污染物降解、促进化学反应等。文章综述了超声空化、水力空化、射流空化和湍流空化效应的机理及其应用的研究进展,为拓展空化的形成方法和应用范围提供了可借鉴的研究思路。The cavitation damages always should be avoided or abated,but the spot energy which is gathered by cavitation can be applied in multitudinous industry field,such as cleaning,pulping,material cutting,rock broking,oil well block eliminating,material super-fine crushing,improving material＇s surface nature,organic pollutes degradation,and promoting chemical reaction,etc.In this paper,mechanism and application research progress of ultrasonic cavitation,water cavitation,jet cavitation and swirling jet cavitation are summarized;thus it provides a salutary lesson for developing cavitation formation techniques and enlarging the areas of its application.
