针状电极场的数值模拟及实验研究

摘要

The use of matlab programming has realized the electric field and potential distributions generated by oblique multi-needle electrodes in conductive medium. We have also realized the displays of potential distribution with three-dimensions. In order to realize the simulation and experimental verification and guidance, we design the experimental method to measure the distribution of multi needle electrode. This experiment through their assembly experiment instrument measuring electrode potential, the experimental results are consistent with measurement results.%利用MATLAB编程实现了任意倾斜多针状电极电流所产生电场的数值计算，实现了三维图形的绘制。为实现模拟与实验的相互验证与指导，设计了多针状电极场分布实验测量方法，通过自己组装的实验仪器测量了电极周围的电势分布，实验与数值模拟结果比较吻合，取得了很好的一致性。
