电位降是当单位正电荷通过一个物质相A的相界面时,因在A的相界面上存在着表面电势,是不定值,故一个物质相中某一位置的“绝对”电位无法确定,也不能测量,人们能测量的只是相同的物相内,两个不同位置的电位差△φ或电势E。
...接触不良导致误差,由一良好电池供应稳定电流,同时加装电位计(potentimeter)以测量与样品串连之标准电阻的电位降(potential drop),同时测量与样品相接之铅块的电位,由所测出的电流与电位,可计算出合金之电导,如欲得电导的真值,怎需准确的测量样品之长度与截面积...

界面电位降与测量电容、薄膜电容及耗尽层电容有关。
The voltage drop of interface is relevant to the measured capacitance, the film capacitance and the depletion capacitance.
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?
但是,通常测量的通电电位并不是管道的真实电位,包含各种IR降。
But the potential on position, which includes IR drops, is not the real protection potential of the pipeline.
