存在一个巨大的IR降(欧姆电位损失)没有补偿或校正，因此曲线图中显示的很多电压并不是界面电位。

There is a huge IR drop (ohmic potential loss) that has not been compensated or corrected for, so the interfacial potentials are nothing like the many Volts appearing in the plots?

在地球的表面，就在我们站立的地方，是这个巨大电池的零电位。

The earth's surface, upon which we stand, is the zero volt end of that battery.
