我们计算了等温化学循环的最大功率效率（EMP），其中粒子吸收发生在固定的化学势下，而粒子释放发生在不同的化学势下。我们得到EMP作为Δμ/kT的函数，其中Δμ是最高和最低储层化学势之差，tis是绝对温度。在线性响应极限Δμ≪kT中，电磁脉冲趋向于预期的通用值1/2。
We calculate the efficiency at maximum power (EMP) of an isothermal chemical cycle in which particle uptake occurs at a fixed chemical potential but particle release takes place at varying chemical potential. We obtain the EMP as a function of Δμ/kT, where Δμ is the difference between the highest and lowest reservoir chemical potentials andTis the absolute temperature. In the linear response limit, Δμ ≪kT, the EMP tends to the expected universal value 1/2.
