中文摘要:
      本文介绍了一种用于多波节复合弯曲振动换能器的穿孔板,并对穿孔板的阻抗变换机理进行了理论分析。本文还对这种换能器的性能进行了测试,并将其用于超声料位仪中,获得了较满意的应用效果。
英文摘要:
      In this paper, a new compound flexural transducer with perforated plate is introduced, and the impedance transforming mechanism of the perforated plate is explained theoretically. In addition, properties of the transducer are measured in this paper. The transducer is applied to ultrasonic level detector, and the result is more satisfying.
