| 中文摘要: |
| 本文所介绍的水听器核准器是由一动圈活塞式换能器和由它激励的一端开口的水柱组成．水柱中的声压由驱动电流的大小来控制．在校准器的水柱中用比较法来校准水听器的低频接收电压灵敏度． |
| 英文摘要: |
| The concerned hydrophone calibrator consists of a column of water that is ex cited by an electrodynamic piston transducer, acoustical pressure in the water column be- ing generated by the driving current of the electrodynamic transducer. The low-frequency receiving voltage sensitivity of an undetermined hydrophone is to be calibrated by compari son with a standard hydrophone in the column of water. |
