| 摘 要： | 本文根据电极传感器是等势体这一特性建立了一种新型的电流激励有限元线电极模型，真实的仿真了物理线电极模型。由得到的仿真结果表明，采用等势体线电极模型可以更细腻地反映实际传感器测量最敏感场域中的电场分布及其变化，有助于从理论上分析测量过程中，电流从流入电极到流出电极的空间分布规律，实现电阻层析测量系统中传感器的优化设计。

| Abstract: | This paper presents a new method of electrode modeling on the basis that a metalized electrode should be treated as an equipotential body in the finite element analysis. The physical width of an electrode is represented by a defined set of nodes through which the current flows in and out of the medium. The simulation results show that this new model could yield more accurate details of electric field distribution particularly in the vicinity of current electrode region. This in turn helps in analyzing the current and sensitivity distribution in the area regard as the most sensitive region in ERT. The results therefore can be used to optimize the design of electrode system for ERT annlications. |
