Raised the idea of constructing hybrid capacitor with a battery based positive electrode and a capacitor based negative electrode, experiment proved that a hybrid supercapacitor with a manganese dioxide based positive electrode and an activated carbon based negative electrode showed very good performance, double electrode specific capacitance could be enhanced to 95. 7f / g, that is 2 ~ 3 times that of the carbon based supercapacitors. furthermore, the maximal voltage of a single cell could be expanded to 1. 5v, as a result, the energy density could be ten times higher than that of a carbon based supercapacitors
本論文中我們提出了將電池哈爾濱工程大學碩士學位論文的正極與電容器的負極結合成混合超級電容器的構想，並成功實現了二氧化錳正極和活性炭負極的組合，構成的錳碳混合超級電容器雙電極比容量可達到95 . 7f / g ，比活性炭超級電容器提高了2一3倍，單體工作電壓可以高達1 . 5v ，從而使能量密度提高到碳基超級電容器的十倍。 -
The paper also found that the capacitance of the positive electrode was much smaller than that of negative one, and then it urged to develop new positive materials to make up hybrid capacitor
同時發現，碳基電容器正極容量遠小於負極容量，這也促使繼續開發新的正極材料組成混合電容器。對於法拉第準電容器材料，重點放在對金屬氧化物的研究上。 -
In the fourth chapter, a fourth - order chebyshev low - pass filter employs new low voltage, highly linear, wide inputting range transconductor is proposed, then we presents a new circuit to tune gm value of transconductor accurately, which employs a new switched - capacitor circuit to change the bias current of transconductor, a third order elliptical function low - pass filter with accurate tunable frequency has been designed using transconductor that is not only with voltage common - mode negative feedback, but also with varying bias - triode transistors which can improve the linearity of this circuit
第四章：提出了一種新的低電壓、高線性度、寬輸入范圍跨導，並由此設計實現了四階切比雪夫（ chebyshev ）低通濾波器，接著提出了一種寬輸入范圍且具有電壓共模負反饋的全差分跨導，並採用一種新的開關電容電路實現跨導值gm精確可調，從而可以設計得到高性能具有精確截止頻率的跨導-電容三階橢圓函數濾波器。 -
We also found that it was the smaller capacitance of the positive electrode that limits the performance of the ac electrode, and the capacitor character reached optimization when the ratio between the mass of positive actived material and that of negative actived material. " 2
但是活性炭電極的正極性能較差是影響電容器性能的重要因素，增大正極活性物質的載量使正負極活性物質質量比約為2 ： 1時，電容性能達到最佳。
