内外波动激活的非平衡反应速率过程

Internal and External Fluctuation Activated Non-equilibrium Reactive Rate Process

Chun-Yang Wang

摘要:

统一考虑了内、外噪声涨落对非平衡开放系统活化速率过程的影响。用反应通量法计算了粒子通过鞍点的概率、速率常数和有效透射系数。我们发现,内部噪声的复杂性总是有害的粒子的扩散。然而,外部调制可能有利于速率过程。

英文摘要:

The activated rate process for non-equilibrium open systems is studied taking into account both internal and external noise fluctuations in a unified way. The probability of a particle diffusing passing over the saddle point and the rate constant together with the effective transmission coefficient are calculated via the method of reactive flux. We find that the complexity of internal noise is always harmful to the diffusion of particles. However the external modulation may be beneficial to the rate process.
