| 摘 要： | 本文从声波动方程出发,引入了一些近似,建立了平均散射声强与物体表面粗糙度,超声频率和接收掠射角之间的闭形解析表达式。并把理论与文献报道的实验结果进行了比较,二者符合较好。因此,本文理论引用的近似在一定程度上正确地预言了粗糙表面的散射声场。

| Abstract: | This paper, Using wave equation, introduces some approximations, Ananalytical expression of the mean scattered sound intensity as a function of surface roughness, ultrasound frequency and reeiver grazingangle is developed. The theory is compared with experimental results inpaper 1], they agree very well. Therefore, the approximations introducedin this paper's theory correctly predict the scattering sound field byrough surfaces. |
