the electrode system is one of the most sensitive and crucial parts in eit system.in this paper a method for eit electrode structure and parameter optimizing design,taking example for compound electrode,has been presented,which is based on the coercive equipotential node model of the line electrode.an imitation research plat-form of electrode structure and parameter optimizing design has been developed.by the methods,the variety influ-ences of electrode structure and parameters on reconstructed image and measurement sensitivity can be obtained.this will provide theory basis for the electrode construction optimizing design of real eit system.
