摘要
采用固态粉压型Ag/AgCl电极对参数已知的水下低频交流电场进行探测。通过改变水中电场信号的特征参数进行对比实验,以检测电极对信号频率和幅值的响应特性。实验结果表明:发射信号在0~4Hz、15-35mV的范围内时,Ag/AgCl电极的探测灵敏度随发射信号幅值的增加而增强,并且探测信号能够真实地反映发射信号的频率特征。最后,提出了电场探测电极的响应性能的表征参数。
The all-solid powder-pressed Ag/AgCl electrode is used to detect the underwater extremely low frequency electric field whose parameters are known. The characteristic parameters of the under water ELFE signals are changed for contrast experiment to detect the response of the electrode to the signal frequency and amplitude. The experimental results show that when the underwater ELFE signal is in the range of 0-4 Hz and 15-35 mV, the detection sensitivity of the Ag/AgCl electrodes will increase with the amplitude of the transmitted signal, and that the detected signal can really reflect the characteristics of signal frequency. And the performance parameter of the Ag/AgCl electrode responsive to the underwater ELFE signal is calculated.
