We experimentally examine the equivalence between the entropy production evaluated from irreversibility of trajectories and the physical dissipation in dissipative processes via electric resistor-capacitor (RC) circuits. The examinations are performed for two nonequilibrium steady states that are driven by an injected current and temperature difference, respectively. Such an equivalence demonstrates a parameter-free method to evaluate the entropy production of a system. The effects of configurational and temporal resolutions are also studied.
我们通过电阻-电容 (RC) 电路实验检验了由轨迹不可逆性评估的熵产生与耗散过程中的物理耗散之间的等效性。检验是针对分别由注入电流和温度差驱动的两个非平衡稳态进行的。这种等效性展示了一种无参数方法来评估系统的熵产生。还研究了结构和时间分辨率的影响。
