摘要：
According to the Born approximation solution of the scattering of three-dimensional elastic waves, the scattering from an ellipse void in a long Al rod is analyzed comparatively. And the identification of flaw geometrical character is discussed with two dimensional inverse Born approximation under low frequency, the corresponding simulation for circular void is carried out.
