The finite element method was applied to calculate the potential distribution and current distribution on a cathodically protected steel pipe pile. In the calculations, the pipe pile, includion both the submerged and buried sections, was considered as a whole.

把钢管桩作为一个整体，用有限元法计算了几种条件下的电位分布和电流分布情况，讨论了水的电阻率、表面涂层、阳极与钢管桩的距离以及阳极长度等因素对电位分布的影响。

The interference corrosion of external steel structures located next to cathodically protected systems was evaluated based on electric field theory of stable currents.

摘要采用稳流电场理论，根据阴极保护体系周围电场分布、受电干扰构件位置和构件表面电化学行为等参数计算阴极保护系统对外部金属构件的电干扰腐蚀。

The statistical maths analysis and sample distribution assumption tests of four factors, i.e., pipe earth potential, cathodically protected potential, corrosion current density of 16Mn mild steel in soil and coating resistance have been accomplished.

根据表征输油管线运行状态的四项参数即管地电位、阴极保护电位、土壤腐蚀性以及防腐层电阻建立了统计分布模型，并对新老管线数据分布模型的均值和方差进行了显著性水平检验。

Current distributions in a cathodically protected crevice between a simulated coating and segmented mild steel electrodes were measured in diluted NaCl solutions. The effects of the control potential, solution conductivity and crevice thickness on the current distribution were studied.

1前言在联合采用绝缘覆盖层和阴极保护技术防止土壤或水中的钢结构，特别是地下油气管线外壁腐蚀的情况下，阴极保护能否完全防止剥离覆盖层下的缝隙腐蚀成为近些年来阴极保护领域的一个研究热点［'］。
