中文摘要:
      在功率超声领域,换能器的阻抗匹配占有相当重要的地位,但有关在较宽频带内都能适用的匹配方案尚少有报道。为满足实验室研究工作需要,我们研制了两套简易匹配装置,可分别对20~50kHz和0.2~2.0MHz频率范围内的超声换能器实现阻抗匹配。
英文摘要:
      Impadance match plays an important role in the range of power ultrasound.But design of impedance matcher suitable to rather broad band has been hardly reported.With request of research work we have studied two simple match equipments,which can well match ultrasonic transducers of frequency ranging from 20~50kHz and 0.2~2.0MHz, respectively.
