The Simulation Research of Circle-Electrode's Electric Field of Steady Current Model

This paper is based on Point-electrode model of electric field of steady current in sea, and regards the seawater as lining,uniformity and apiece-direction congenialitily half-infinity conductor space. Founding on the comparability of steady current field and static current field,the paper calculates the distribution of circle-electrode's electric potential of the steady current in the three-layers medium(air-sea water-seabed) by image method and gets the expession. Thus the paper takes the model of the circle-electrode's electric field of steady current of in the sea .
