| 摘 要： | 我们研究了采用偶极子接收换能器的驻波场校准系统，通过调整该系统水小箱中的驻波形式，实现局部空间内的均匀声场，从而可以用来进行声压水听器的比较法校准，并与振动液柱法校准结果相比较，从２０Ｈｚ～２０００Ｈｚ范围内两种方法测得的接收灵敏度偏差小于１ｄＢ。

| Abstract: | We have developed a standing wave calibration system for dipole hydrophone. According to regulating the standing wave form in a small water tank of the system, the acoustical uniform region in the part of the tank is achieved and the hydrophones are calibrated in the system by the comparison method. The receiving sensitivity with errors under 1dB is obtained by utilizing the system and the vibrating liquid column calibrator over the frequency range from 20Hz to 2000Hz |
