摘　　要：实海测试中发现海水流动对银-氯化银电场探测电极的性能影响很大。为此选择以硅藻土为基材,对银-氯化银电极进行包覆处理,通过连续检测银-氯化银电极对在静止、低流速和高流速等情况下的极差噪声的变化。通过时域噪声振动幅值与频域噪声在不同频段噪声变化,研究包覆处理的效果,结果表明:海水流动会显著增加银-氯化银电极的极差噪声,且流速越快噪声增幅越大。所设计的包覆层能够有效地抑制水流对电极对极差噪声的影响。Water flow has great influence on Ag/AgCl electrode in practical test.So the diatomaceous earth is chosen as the mean coating material to test the self-noise of Ag/AgCl electrode in different surroundings,such as static and different flow of sea water.The amplitude of time domain noise and frequency domain noise in different frequencies are used to analyze the effect of cladding process.The results show that the water flow of sea water significantly increases the self-noise,and the increase of noise is positive to the water speed.The cladding layer can prevent the influence of water flow on self-noise.
