With the triode working characteristic in saturation field we implemented the conversion from constant-currentcharge to tiny-current charge and decreased leakage.
利用三极管在饱和区的工作特性，方便地实现了由恒流充电至涓流充电的转换，减不了充电过程中的水损耗。

Elemental composition and BET surface area of pyrolysis carbon were investigated. X-ray diffraction pattern and constant-currentcharge-discharge properties of pyrolysis carbon were studied.
元素分析、氮气物理吸附和X射线衍射分别考察了裂解炭的元素组成、BET比表面积以及微晶结构变化；
