[求助] 发150金币帮助翻译一段文字

本人由于时间紧张,发150金币求高手帮忙翻译一下以下文字,谢谢
由图5可见,添加未经任何处理AC的电极,其对应的氧化电流要比经过特定处理后的电极所对应的氧化电流要大,而且该电流峰对应的积分电量(放电容量)呈现减少的趋势。对上述现象可进行如下解释:活性炭颗粒中存在大孔、中孔、微孔三种不同类型的孔,其中对于电极放电容量影响最大的是中孔,而现在的三种试样中,中孔的量出现了较大幅度的变化,在(b)、 (c)试样中,有大量的中孔被铅粉或氧化铅粉吸附,从而堵塞了部分孔隙结构,导致电极中中孔比例下降。图5中还可以观察到,在-0.2V附近,理应放电结束,电流几乎变为零,但目前的情况是电极仍然以一定的氧化电流持续一段时间,即电极多放出了一定的电量。根据电极反应原理分析,推测此处的电流可能来自于高比表面活性炭与硫酸电解液所形成的固液相双电层电容放电。

As shown in figure 5, oxidation current of the modified  electrode with the untreated AC was much bigger than that modified with treated AC. Furthermore,  a obvious reduce of corresponding Integral power(discharge capacity) was presented. the possible reason was following: there are three  types of activated carbon particles: macropore,mesopore and micropore. the discharge capacity of the electrode was matters most withthe mesopore. in here, the amountof the  mesopore was substantial changes in the three samples. a large number of mesopore was clogged with lead powder or oxidation adsorption lead oxide, which blocked part of the pore structure, leading to the drops of the percentage of mesopore on the electrode  in the in (b), and (c) sample.   discharging  process should be ended near 0.2 V(current almost to zero),  but continue currentstill last for a period of time  (more rechangeing)be observed as shown in Figure 5. According to the electrode reaction principle , speculated that the current may come from high surface and electrolyte activated carbon sulfuric acid formed by solid liquid electric double layer capacitance discharge.
