摘要
本文假设随机粗糙表面符合Ｇａｕｓｉａｎ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．本文理论结果与文献［１］报道的实验结果符合较好．
In this paper,the mean scatterd sound intensity by asurface described by a Gaussian distribution of heights is calculated. A new formulation of the mean scattered sound intensity as a function of surface roughness,ultrasound frequency and receiver grazing an gleis developed.The theory is compared with experimental results in paper ,they agreed very well.
