摘要: 以磁场对声致发光影响研究为基础,结合对声致发光时气泡内状态的现有认识,从气泡外、气泡表面及气泡内各 层次着手,通过理论估算方法分析磁场与气泡可能存在的各种耦合机制,并对特定磁场条件下两种相互作用能量进行数量 估计,评判两者可能存在的各种耦合方式的重要性,进而推测两者相互作用机制.

Abstract: In this paper, the potential various coupling mechanisms between the magnetic field and the sonoluminescing bubble were studied by a theoretical estimation method.The phenomenon of bubble sonoluminescence is an important way to reveal the mechanism of ultrasound cavitation.The magnetic field effects on the sonoluminescing bubble were studied from three areas, including outside the bubble, the bubble surface and inside the bubble.We also pointed the degree of importance of all possible various coupling ways bettwen the magnetic field and the sonoluminescing bubble and infered a interaction mechanisms from the effects.

Key words: approximate estimation, sonoluminescence, magnetic field, coupling mechanism
