The polarographic catalytic wave of Cobalt in Ethylene Diamine-Nitrite solution has been applied to determine trace Cobalt in soil and plant by staircase voltammetry on static mercury dropelectrode.
用阶梯扫描伏安法研究了钴—亚硝酸盐—乙二胺体系在静汞电极上的催化波，用以测定土壤和植物中的微量钴。

Otherwise, the current drawn from the cell electrodes will cause a voltage drop across the internal resistance of the electrode and may polarize the cell.
否则，从电池电极吸取的电流将会在电极的内阻上产生电压降并可能使电池极化。

The results of measurements on paste type R20 battery showed that Zn electrode polarization played an important role on the sharp drop of cell voltage near the end of the discharge.
