| 摘 要： | 本文假设随机粗糙表面符合Ｌａｐｌａｃｉａｎ分布，建立了来自粗糙表面的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。其结果的近似程度比文献［１］予言的更好。

| Abstract: | In this paper,the mean scattered sound intensity by a surface described by aLaplacian distribution of heights is calculatcd.A new formulation of the mean scattered Sound intensityas a function of surface roughness,ultrasound frequendy and receiver grazing angle is developed.Theapproximation of the results is better than that of the paper1]. |
