摘　　要：运用有限单元法,并结合电化学测试,研究了电场作用下阵列电极的直径及其排布方式对电流密度分布的影响。结果表明:随着阵列电极直径的增大,电流密度变小;正多边形排布的阵列电极上的电流密度分布最均匀;以其他形式排布时,越靠近几何中心的电极上的电流密度越大。Influences of arrayed electrode diameter and arrangement mode on the distribution of current density under the action of pure electric field were studied by finite element method in combination with electrochemical measurement.Results showed that the current density decrease as the diameter of arrayed electrode increase.When arrayed electrode arranged in an equilateral polygon,the current density distributed uniformly.However,when arrayed electrode arranged in other forms,the current density close to electrode geometric center became higher.
