通过界面双电层电容值的变化来解释脉冲电化学光整加工提高精度的根本原因；
The reason for the improvement of precision by the EP is the change of double layer capacity value.
研究证明，电化学电容所具有的大容量是由于电极表面的双电层电容和氧化还原反应导致的“准电容”的共同作用而引起的。
The large capacitance exhibited by these systems was demonstrated to arise from a combination of the double-layer capacitance and pseudo-capacitance associated with surface redox-type reactions.
这些材料都具有一定的电化学储氢作用，煅烧玉米茎后所得多孔碳材料是一种较好的双电层电容电极材料。
XRD and TEM indicated that these materials are disordered porous carbon materials with many nanochannels of different sizes. They have the ability of electrochemical hydrogen storage.
