| 摘 要： | 本文提出一种能从多层介质的超声反射脉冲提取有用的被检测信号的方法,被检测信号的特点是产生该信号的介质不与声学探头直接接触,而且该信号在多层介质中的衰减必须予以考虑。这种方法能用于多层介质中超声无损检测。

| Abstract: | This paper proposes a method, by which the useful measured signal can be obtained from the ultrasonic reflection pulse of a multilayered medium. A proximity acoustic sonde indirect contact with the reflecting medium is used. Attenuation in the multilayered medium should be taken into account. This method can be used for ultrasonic NDT in a multilayered medium, for example cement bond log. |
