摘要
利用边界积分方程和机电互易原理得到声显微镜的模型，并对模型简化，得到了一个可以反演的形式，并利用频率和距离两参数的等效性，提出了一种反馈材料固液界面反射系数的方法。
The transient pulse echo of acoustic microscope has been computed by a timedomain bound-ary element method and electro mechanical reciprocity theory. A simple equation of the pulse echo has been obtained under some approximation and a frequency depth inversion method has been forwarded.
