摘要翻译：
本文对RC$电路中被驱动布朗运动和电噪声的实验进行了完整的分析，表明热力学熵产生可能与这些非平衡系统的统计描述中时间反转对称性的破缺有关。对称性破缺可以用单位时间内的动力学熵来表示，一个是正向过程，另一个是时间反向过程。这些单位时间内的熵表征了非平衡涨落的时间序列中的动态随机性，即时间无序性。它们的不同给出了众所周知的热力学熵产生，从而发现它的起源是动力随机性的时间不对称性，即在被驱赶出平衡的系统中的时间无序。

英文摘要：
We here present the complete analysis of experiments on driven Brownian motion and electric noise in a $RC$ circuit, showing that thermodynamic entropy production can be related to the breaking of time-reversal symmetry in the statistical description of these nonequilibrium systems. The symmetry breaking can be expressed in terms of dynamical entropies per unit time, one for the forward process and the other for the time-reversed process. These entropies per unit time characterize dynamical randomness, i.e., temporal disorder, in time series of the nonequilibrium fluctuations. Their difference gives the well-known thermodynamic entropy production, which thus finds its origin in the time asymmetry of dynamical randomness, alias temporal disorder, in systems driven out of equilibrium.
