空间关联与非均匀化学反应体系非平衡定态的涨落熵产生

SPATIAL CORRELATION AND ENTROPY PRODUCTION OF THE FLUCTUATIONS AT NONEQUILIBRIUM STEADY STATE OF INHOMOGENEOUS CHEMICAL REACTION SYSTEMS

用随机位方法分析了理想化学反应。扩散体系分布函数非平衡蜕变的热力学效应，揭示了非Ｐｏｉｓｓｏｎ空间关联对非平衡态熵的影响，并计算了熵产生。证明涨落熵产生完全来自化学反应局域涨落，与通过扩散耦合引起的各体积元之间的空间关联无关。

By a stochastic potential approach the thermodynamic effects of the nonequilibriumdeviation of distribution function of the ideal chemical reaction systems are analyzed. Furthermorethe influences of the non-poisson spatial correlation to both nonequilibrium entropy and entropyproduction are calculated. It truns out that the entropy production of the fluctuations originatestotally from local fluctuations of chemical reactions,independent of spatial correlations due to thediffusion coupling among cells.
