| Abstract: | The soil resistance was applied to stand for the soil difference and the new mathematical model in heterogeneous soil was established.The boundary conditions take activation polarization and concentration polarization into account.Confirming the numerical simulation with cathodic protection simulation device proves the feasibility of employing this model to calculate cathodic protection potential. |
