利用水平直流电偶极子在海洋环境三层模型中的标量电位解析表达式,结合仿真分析与实验室实际测量,并以铂铌丝电极对模拟电偶极子,分别比较分析空气-海水界面、海水-海床界面对标量电位的影响情况。结果表明:在现有条件下,空气-海水界面上的电位比没有界面存在时的电位近增强1.6倍,海水-海床界面上的电位近增强1.25倍;海床的电导率越小,海水-海床界面处的电位增值越大;界面对标量电位的分布特性没有其它影响。
Based on the analytical expression of scalar potential in the three-layer model of marine environment with the horizontal DC dipole, combining the simulation analysis with the actual measurement in the laboratory, and comparing the air-sea interface with the platinum-niobium wire electrode and the analog electric dipole, Effect of seawater - seabed interface on scalar potential. The results show that under the existing conditions, the potential at the air-sea interface is nearly 1.6 times higher than that at the absence of an interface, and the potential at the seawater-seabed interface is almost 1.25 times stronger. The lower the conductivity of the sea bed, - The greater the potential increase at the seabed interface; the interface has no other effect on the distribution characteristics of the scalar potential.
