摘　　要：基于流动电解液导致电极表面双电层结构变化的特性,解释了海水中电极拖曳天线在流动电解液中的运动极化噪声机理,分析了电极对在流动海水中的噪声变化规律。并使用全固态银/氯化银电极设计进行实测实验,结果表明电极对拖曳天线运动极化噪声受周围流动导电液体影响,且影响主要集中在低频频段,频率越高流速影响越小。并且电极对极差电压与海水流速变化率成正比,噪声信号与加速度传感器输出信号具有强相关性,与理论分析一致。Based on the characteristics of the change of the electric double layer structure on the electrode surface caused by the flowing electrolyte,the motion polarization noise mechanism of the electrode towed antenna in the flowing electrolyte in seawater is explained,and the noise change law of the electrode pair in the flowing seawater is analyzed.The experimental results show that the polarization noise of electrode pair towed antenna is affected by the surrounding flowing conductive liquid,and the influence is mainly concentrated in the low frequency band.The higher the frequency is,the smaller the influence of flow velocity is.Moreover,the electrode pair range voltage is directly proportional to the change rate of seawater velocity,and the noise signal has strong corre⁃lation with the output signal of acceleration sensor,which is consistent with the theoretical analysis.
