[交流] 【求助】求助极化曲线问题 已有2人参与

以下是corrosion science 主编建议,

You must describe IN THE PAPER want you have done with regard to Tafel slopes and their conversion to corrosion current density.  You must also describe IN THE PAPER what the accuracy of the corrosion current density is, and discuss BOTH these issues IN THE PAPER.  

You should query whether it is even possible to measure Tafel slopes from this system.  You can do this in many ways.  One matter which you could look at is whether the polarisation curves are in fact ohmic in behaviour, and you can do this by plotting I vs E on linear axes.  Such linear behaviour could occur for example, particularly in the cathodic region, if the current is controlled by electron transfer through a resistive oxide film.  If the ohmic plot is linear, then clearly the Tafel equation cannot be fitted.

I might also suggest that the Tafel slopes for the cathodic reaction look very large.
编辑提出的三个问题各是让咋改啊,不明白啊~~~~~
万分感谢!!!急
