cathodic current density的意思|示意

Results show that it is difficult to make cathodic protection on bare steel because of large current density, and that cathodic protection is suitable for coated steel.

试验结果表明，对裸钢采用阴极保护时，所需电流密度较大，实施难度较大；而对有涂层的钢则更宜采用阴极保护措施。

Through adding assistant complexing agent and controlling initial current density, cathodic polarization was intensified in cyanide-free electrolyte.

通过添加辅助络合剂和控制起始电流密度的方法，可以增强无氰电镀时阴极的极化。

With the decrease of film thickness, the cathodic polarization current density of 7B04 Al-alloy increases, and the anode reaction is suppressed.

液膜厚度减小，7B04铝合金阴极极化电流密度增加，阳极反应受到抑制；

The minimum magnetic field intensity needed to induce significant effect on cathodic limiting diffusion current density decreased with increasing ferric ion concentration.

引起极限扩散电流密度明显增加的临界磁场强度随三价铁离子浓度增加而减小。

The 2-d finite element method was an effective method to calculate the potential and current density distribution 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。

Therefore it is significant to find a simple method to describe the distribution of potential and current density under the cathodic protection.

由此可见，寻找一种能满足工程要求的简单方法来求解船体的保护电位及电流密度分布问题具有重要意义。
