The 2-d finite element method was an effective method to calculate the potential and currentdensitydistribution of cathodic protection fields.
有限元法已被证明是计算阴极保护场中电位、电流密度分布的有效方法。

The results showed that the component contents, particle size distribution, discharge rate obviously affected currentdensitydistribution, but less affected the SOC.
结果表明，材料的组分含量、粒度分布、放电倍率对电流密度影响较大，对SOC状态影响较小。

By using this kind of shielding effects, the electric currentdensitydistribution can be improved, the back-corona can be reduced and the high voltage and low current state can be obtained.
