We provide a strategy for the exact inference of the average as well as the fluctuations of the entropy production in nonequilibrium systems in the steady state, from the measurements of arbitrary current fluctuations. Our results are built upon the finite-time generalization of the thermodynamic uncertainty relation, and require only very short time series data from experiments. We illustrate our results with exact and numerical solutions for two colloidal heat engines.
我们提供了一种策略，可根据任意电流涨落的测量结果，精确推断稳态非平衡系统中熵产生的平均值及其涨落。我们的结果基于热力学不确定性关系的有限时间推广，并且只需要来自实验的非常短的时间序列数据。我们用两个胶体热机的精确解和数值解来说明我们的结果。
