中文摘要:
      本文提出了一种利用补偿原理直接测量压电换能器串联谐振频率fs和并联谐振频率,fp的新方法一补偿法。在这种方法测量原理的基础上,进行了实际测量,并设计了一种实用的测量电路。采用此方法测量的测量结果与电桥法的结果相符得很好。
英文摘要:
      Put forward in this paper is a new and simple method for measuring the serial resonant frequency fs and the parallel resonant frequency fp of a piezoelectric transducer. The main point of this method is to cancel the susceptance of the transducer by paralleling an inverse susceptance to get a pure admittance or, to cancel the reactance by serializing an inverse reactance to get a pure resistance. A practical measuring circuit is given. The measured result by this method coincides with that by the bridge method very well.
