运用菲涅尔环带法,建立了计算水浸聚焦探头声束轴线上的声压分布的数学模型.按照这一数学模型编程计算的声束轴线上的声压分布规律与实测结果相符合.
The mathematical model for calculating the sound pressure distribution on the beam axis of water immersion focusing probe is established by Fresnel zone method.The distribution of sound pressure on the beam axis calculated by this mathematical model is consistent with the measured results.
