For any irreversible process, the efficiency is less than that of the Carnot cycle. 任何不可逆过程中，效率是小于的卡诺循环。
The results show that iron-amine complex gets one electron as the redox mediator on the electrod, this is a quasi-reversible diffusion controlled process. 结果表明，铁胺络合物在悬汞电极上的电化学还原过程为受扩散控制的准可逆过程，电极上发生单电子转移。
