zero current potential

基本解释

Through electrostatics and examples of low-frequency alternating current and direct-current circuit, the problem of zero potential point is queried and clarified.
通过静电学、低频交流、直流等电路实例，质疑了电势零点问题，并对此进行了澄清。
A constant current is applied to the center electrode and an auxiliary current of the same polarity that is automatically adjusted to maintain zero potential is applied to the guard electrodes.
测井时，主电极通以恒定的电流，屏蔽电极通以极性相同的辅助电流，自动调节屏蔽电极上的电流，使得两个屏蔽电极上保持相同的电位。

零流电位
Zero current potential E_(zcp) of I-E curves was measured and shows linear to log C_(Cu)~(2+) in the wide range of 3.0×10~(-6)～4.0×10~(-5) mol·L~(-1) with the slope 59 mV/pCu~(2+).
选取零流电位E_(zcp)作为测量参数,探讨了零流电位E_(zcp)与Cu~(2+)离子的关系。实验结果表明:零流电位E_(zcp)与Cu~(2+)浓度对数值log C_(Cu~(2+))在3.0×10~(-6)～4.0×10~(-5)mol·L~(-1)范围内呈线性关系,斜率为59 mV/pCu~(2+)。
