摘　　要：由于潜艇在声安静技术方面取得的进展，需要用主动声呐作为辅助手段来探测潜艇，从而大大促进了低频大功率发射换能器的研究。本文论述了对低频大功率发射换能器的要求和限制。The advances in the acoustic quieting of submarines will necessitate the use of active sonar as on adjunct as a means of dedecting submarines, bring about a deep research in high power,low frequency projectors The needs and limiting factors for high power, low frequency are discussed and different type projectors of high power and low frequency are compared

关 键 词：发射换能器 低频 大功率 主动声呐 声呐
