摘要：

The scattering of low frequency ultrasound by a cluster of arbitrary ellipsoidal inclusions is studied numerically, using the extended quasi-static approximation. The statistical variations in the scattered intensities are investigated. The relationship between the back-scattered signal and the attenuation of the ultrasound is determined. The implications of these results for the ultrasonic examination of steels containing inclusions are discussed.
