一个大的偏差函数的数学特征的统计特性的非典型事件。近年来，在非平衡统计力学中，大偏差函数已被用来描述普遍规律，如涨落定理。尽管如此重要，大的偏差函数在实验室实验中并不容易获得。因此，为了理解大偏差函数的物理意义，有必要更详细地考虑它们的实验可测性。这方面的大偏差进行了讨论，提出了未来的问题。
A large deviation function mathematically characterizes the statistical property of atypical events. In recent years, in non-equilibrium statistical mechanics, large deviation functions have been used to describe universal laws such as the fluctuation theorem. Despite such significance, large deviation functions have not been easily obtained in laboratory experiments. Thus, in order to understand the physical significance of large deviation functions, it is necessary to consider their experimental measurability in greater detail. This aspect of large deviation is discussed with the presentation of a future problem.
