Abstract:

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 remarkable peak at the equal-probability point. This behavior is easily understood by the approximation of probability distribution. It is revealed that the behavior at the equal-probability point, like the first-order transitions in equilibrium systems, possesses the feature of first-order-like transitions.

Key words: Bistability state, Fluctuation, Nonlinear, Phase transition
