在最近已被证明，亥姆霍兹自由能差的两个平衡配置的系统可以从有限时间（非平衡）测量的工作进行切换系统的外部参数的合奏。在这里，这个结果作为一个恒等式在主方程形式主义中建立起来。例子进行了讨论，并提供了数值说明。
In has recently been shown that the Helmholtz free-energy difference between two equilibrium configurations of a system may be obtained from an ensemble of finite-time (nonequilibrium) measurements of the work performed in switching an external parameter of the system. Here this result is established, as an identity, within the master equation formalism. Examples are discussed and numerical illustrations provided.
