Optic fiber hydrophone has the highest sensitivity among current underwater sensors. 光纤水听器作为目前水下声场探测灵敏度最高的器件,所具有的优异性能,使其成为未来新型声纳装置的最佳选择。
The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe. 目前脉冲星普查的有限探测灵敏度和大的频率漂移,使我们难以观测到更遥远的脉冲星。
