  1. Finally, some important conclusions were drawn, that is, using distributed pzt transducers, ultrasonic guided waves are generated and received in a pipe. usually, there are many different modes of guided wave propagating in the pipe and these modes are generally dispersive, the specific exciting signal of a harming windowed toneburst with a central frequency of 70khz for decreasing the effect of dispersion was selected. and guided wave are generated using 16 distributed pzt transducers in a circumferential direction for suppressing flexural modes

    首先,對當前本課題研究領域的進展作出綜述,並簡要介紹與超導波技術相關的理論基礎;其,建立了一套有效的實驗裝置,在此實驗裝置基礎上,重點研究了採用分散式pzt傳感在管中激勵和特定模態超導波的方法:根據在管狀波導中傳播的超波具有頻散現象及多模態特徵,選擇具有單一頻率的特定信號激勵超導波,使其頻散最小;同時採用分散式傳感抑制不同模態的波型。
