摘　　要：对传统的管内阴极保护电位分布计算方法进行改进，以原位测得的极化曲线为依据，对阴极保护条件下不锈钢管内电位分布进行数值模拟。结果表明，其理论值与实测值符合较好，而且能够预测分散能力随时间的变化。Based on the polarization curves measured on original potential,a numerical simulation inside stainless steel pipes under cathodic protection after the improvements of the conventional potential distribution calculations of the cathodic protection inside stainless steel pipes was made.The results show that the theoretical value is in good agreement with the measured value,and the numerical simulation can predict distribution capacity change with time.
