摘要：

We consider the energetics of a multistable system driven by a nonthermal fluctuation. An analytical expression of the efficiency of energy transformation of fluctuation into coherent energy is derived for a process driven by a dynamic noise, in an overdumping limit of the system. The method is applied for the calculation of chaotic noise.
