具有双稳态的化学反应中的涨落现象

摘要

In this paper, the fluctuation of the bistability chemical reactions system is studied.The fluctuation is always very small except in the narrow region, where we find a remarkablepeak at the euual-probability point. This behavior is easily understood by the approximation ofprobability distribution. It is revealed that the behavior at the equal-probability point, like thefirst-order transitions in equilibrium systems, possesses the feature of first-order-like transitions.
