In this case there is a rather good correlation between resistance, half-cellpotential and corrosion rate mapping.
在这个案例里，腐蚀速率图、电阻率、半电池电位存在着很好的相关关系。

The corrosion of the reinforcing steel in concrete is an electrochemical process, and the half-cellpotential is on of the utmost characters in estimating the condition of the rebar.
