摘要
用声反射和折射定理分析气泡与水的分界面处入射声波的反射与折射作用,振动类比电路和气泡的多阶谐振公式分析气泡的声散射作用,建立尾流中气泡的主动声特性模型。通过分析尾流中气泡的主动声反射/散射模型,为后续的多个气泡及尾流的主动声反射/散射模型奠定基础。
The theory of reflection and refraction is used to analyze the sound wave on the interface of the bubbles and water. The resemblance between vibration and electric theory and the multi-stage resonance formula is used to study the scattering of the bubbles in the water. After analyzing the active acoustic characteristic of the bubble, the active acoustic reflection/scattering model of the bubble is created in the ship wake. The following research on the active acoustic characteristic of multi-bubbles and ship wake is based on these.
