中文摘要:
      本文介绍了一种3-3连结复合压电宽带发射换能器。探讨了它的结构设计及计算方法。进行了实测与应用,作出了优缺点评价。换能器中心频率200~500KHz,带宽Q为2.0~2.8.最大发送响应149.7dB.横向耦合小,波形简单,余振短。在高分辨率检测技术中有独特的应用。
英文摘要:
      A 3-3 connective composite piezoelectric transmitting transducer is introduced in this paper. the construction, calculation and design method are discussed. The measuring result and application effect have been evaluated, The central frequency of the transducer is 200-500 KHz. The quality factor Q is 2.0-2.8, and the max. transmitting response is 149.7 db. The transducer has a minimal transverse coupling and simple wave shape, and is very short the after-pulse. It can be used in the high resolution detecting equipment.
