摘　　要：空化是液体特有的一种复杂流体动力学现象,研究空化机理具有十分重要的意义,涉及众多领域.本文从最新研究成果:空化初生、空化运动方程、空化流场的实验测量及空化流场的数值模拟等方面综合分析了空化现象形成的机理,介绍了空化技术在实践中的应用,且进一步对空化的研究做了展望.The mechansim studies of cavitation which is a kind of complex hydrodynamics phenomena have significant on the multitudinous field. The formation mechansim on cavition is reviewed for therecet advances, including the incipient cavition,the bubble equations of motion,the experiment as well as the numeical simulation. Furthermore, the progress of technology application in practice is presented in detail.And some prospective cavition topics in this field are stuggested.
