摘　　要：鉴于超声单波(回波)金属检测仪存在不能检测损伤大小和形状的问题,我们依据多波地震勘探的理论,对超声多波金属检测仪进行了研究,并对其特性、原理及与其配套的三分量换能器等进行了分析,取得了实质性突破。According to the theory of the multi-wave seismic exploration, and due to the fact that the ultrasonic multi-wave metal detector cannot locate a crack and detect its, size and shape, this article studies the principle and characteristics of the ultrasonic multi-wave metal detector and also the 3-heft energy-exchange instrument in match with the ultrasonic multi-wave metal detector. The results demonstrate substantive achievement.
