论文摘要
波动关系是现代热力学的一个里程碑，只有在可以测量一组基本电流时才能建立。在这里，我们证明，如果携带观察值``自己的节拍''，也就是说，它也适用于隐藏过渡的系统，也就是说，在固定数量的可见过渡之后停止实验，而不是外部时钟时间的过去。这表明热力学对称性在过渡空间中描述时对信息丢失具有更大的抵抗力。
The fluctuation relation, a milestone of modern thermodynamics, is only established when a set of fundamental currents can be measured. Here we prove that it also holds for systems with hidden transitions if observations are carried ``at their own beat,'' that is, by stopping the experiment after a fixed number of visible transitions, rather than the elapse of an external clock time. This suggests that thermodynamic symmetries are more resistant to the loss of information when described in the space of transitions.
