With sufficient forward bias, the diffusion capacitance can easily exceed the space charge region capacitance. 当正向偏压足够高时,扩散电容很容易超过空间电荷压电容。
The effect of the diffusion capacitance can be troublesome. 扩散电容会引起麻烦。

Through the impedance spectra simulated with equivalent circuit, the relation of the content of conductive material and adhesives with the parameters is researched. The parameters include the resistance of electrode, polarization resistance, diffusion resistance, electric double layer capacitor, limiting capacitance and so on. 通过对等效电路和交流阻抗图谱的模拟分析,研究了电极电阻、极化电阻、扩散电阻、双电层电容、极限容量等参数与导电剂、粘结剂含量的关系。
The thermal diffusion between different metals also can be improved by increasing the annealing time. The as-prepared composite film electrodes annealed at 300 ℃ for 4h presented specific capacitance of 1211 F · g-1. 同样,增加热处理时间也可促进金属间的热扩散程度,在300℃热处理4h得到的复合膜电极给出了1211F·g-1的比电容值。
