摘　　要：推导了机织电极交织电阻的大小范围。建立了场点电势、电极电势、电极电势差三者的数学模型。电极电势为交织点处场点电势的加权平均。采用仿真方法探讨了电极位置、尺寸、接触电阻对电极电势的影响。结果表明,存在两个极值点使电极电势分别取得极大值、极小值;电极电势极值绝对值随电极尺寸增大而减小;接触电阻期望非远大于交织电阻时,电极电势不受接触电阻影响。Range of interlacing resistance of woven electrode is induced. Mathematical models of field point potential, electrode potential and electrode potentials difference are constructed. Electrode potential is the weighted mean of field point potentials at interlacing points. Effects of position, size of electrode, and contact resistance on electrode potential are investigated by simulation. Results indicate that there exists two extreme value points at which electrode potential reaches maximum and minimum, respectively The absolute value of electrode potential extreme value decreases with the increase of electrode＇s size. The electrode potential is independent of contact resistance if the expectation of contact resistance isn＇t far greater than the interlacing resistance.
