In the most basic sense PCR simply means that the electric current applied to the cell is reversed periodically - but unlike pure AC the average (nett) current is still biased in one direction (otherwise there is no net electrochemical action). ==Equipment== The earliest (and simplest) PCR arrangements simply use an offset AC (sine wave) voltage where the potential will reverse for a time each cycle (e.g. a half wave rectifier with leaky diode). Modern PCR equipment uses electronic switching to do the reversal allowing a square wave form with precise control of the timing and currents for forward and reverse currents. Often PCR cycles will incorporate zero current phases as well (this could be seen as a variation on pulse charging adding the short reversals during rest periods). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Periodic current reversal」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
