zero current potential

基本解釋

Through electrostatics and examples of low-frequency alternating current and direct-current circuit, the problem of zero potential point is queried and clarified.
通過靜電學(xué)、低頻交流、直流等電路實例，質(zhì)疑了電勢零點問題，竝對此進(jìn)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.
測井時，主電極通以恒定的電流，屏蔽電極通以極性相同的輔助電流，自動調(diào)節(jié)屏蔽電極上的電流，使得兩個屏蔽電極上保持相同的電位。

零流電位
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+).
選取零流電位E_(zcp)作爲(wèi)測量蓡數(shù),探討了零流電位E_(zcp)與Cu~(2+)離子的關(guān)系。實騐結(jié)果表明:零流電位E_(zcp)與Cu~(2+)濃度對數(shù)值log C_(Cu~(2+))在3.0×10~(-6)～4.0×10~(-5)mol·L~(-1)範(fàn)圍內(nèi)呈線性關(guān)系,斜率爲(wèi)59 mV/pCu~(2+)。
