The " electrode" is not equal to the electric pole. Because every electrode of a voltaic cell consists of two contrary poles.

由于原电池中每一个电极体都包含着两个相反的电极，故"电极体"并不等于电极。

The hydrophobic adsorption film gradually grows and passivates on jamesonite from -78 mV to 42 2 mV.The electrode process of jamesonite at 522 mV is quite controlled by the reaction that is depended on ion diffusion.When the electrode potential is over 622 mV,the hydrophilicity on jamesonite becomes strong due to covering an amount of PbSO4 from the electrochemical reactions.

Objective: Pino et al reported that strip lesions were produced when the distance between two probe was 2 to 6mm, and it resulted in unipolar lesions when they were spaced more than 6 mm apart. However, in clinical studies and some other reports, bipolar radiofrequency treatment was also effective when the distance was 10mm. Therefore, we duplicated Pino et al's experimente to study the lesion morphology when the distance of two radiofrequency cannulae was arranged between 2 and 10mm.
