摘要: The dissipative mechanisms of an isolated bubble in water for sound wave are analysed on the basis of the linearized theory of oseillations of a gas bubble. It isshown that the dissipative effects are obvious and contain the scattering and absorptionof sound by a bubble the heat conduction is decisive in the dissipative effects of bu-bble; and the dissipative effects are maximum at resonance.
