我又来问问问题了，电化学的，看不太懂，想请大家帮忙看下~

Electrochemical Measurements All the electrochemical measurements, either cyclic voltammetry (CV) or impedance spectroscopy,were performed with a Gamry 600 potentiostat in a three electrode configuration. The reference electrode was a KCl saturated Ag/AgCl electrode (CHi instruments, ref 111) and the auxiliary electrode was a platinum wire (CHi instruments, ref 115). The (PAH-MMT)n films were deposited on amorphous carbon working electrodes (CHi instruments ref 104). The electrodes were polished with alumina paste for three cycles of polishing (each one lasting over 2 min) and then intensively sonicated in distilled water. Before the deposition of the PEM ?lm, CVs were acquired at 50mV 3s-1 by cycling the potential di?erence between 0.10 and +0.70 V and back to0.10 V vs Ag/AgCl at a scan rate of 50 mV 3s-1. These CV curves were acquired in the presence of 10 mM Tris bu?er + 150 mM NaCl with or without added potassium hexacyanoferrate at 1 mM (Sigma P9387). The PEM ?lm was deposited on the working electrode only if the potential di?erence between the potential corresponding to the maximum oxidation current and the potential of the maximum reduction current were not separated by more than 80 mV. 能大致解释下，或者翻译下噜，不甚感激！ |
