摘要
本文从气泡壁面线性运动方程出发，对水中孤立气泡的声耗散机理进行了分析．结果表明：气泡对声波具有明显的耗散作用；耗散作用由声散射和声吸收两部份组成；热传导在气泡对声波的耗散作用中起决定性作用；气泡处于谐振时，对声波具有最大的耗散作用．
The dissipative mechanisms of an isolated bubble in water for sound wave are analysed on the basis of the linearized theory of oscillations of a gas bubble.It is shown that the dissipative effects are obvious and contain the scattering and absorption of sound by a bubble;the heat conduction is decisive in the dixsipative effects of bubble; and the dissipative effects are maximum at resonance.
