  effective entropy
We introduce fundamental theoretical macroparameters: the effective entropy and the effective action.
      
Because the effective entropy is nonzero at low temperatures, we can write the third law of thermodynamics in the form postulated by Nernst.
      
We establish that the ratio of the effective action to the effective entropy in the low-temperature limit is determined by a holistic stochastic-action constant depending on the Planck and Boltzmann constants.
      
For example, an approximate Gaussian with 0.5 and 0.1 had an effective entropy only 10% lower than that of a uniform distribution of values.

By means of the stochastic thermodynamic formalism of finite chemical reaction systems under the influence of external noise,the effective master equation and the effective stochastic entropy balance equation are set up for a simple coupled chemical reaction system with membrane equilibrium.The statistical content of corresponding effective stochastic entropy production is then analyzed,and the stochastic thermodynamic effects of internal fluctuation and external noise due to chemical reaction coupling are revealed for such a simple model.According to the stochasitc simulation of macroscopic perturbation,the influence of chemical reaction coupling is shown on the stability behaviors of the reaction systems at nonequilibrium steady states.

根据受噪声作用的有限化学反应系统的随机热力学理论,以存在膜平衡交联的简单反应模型为例,建立了交联体系的有效主方程及有效随机熵平衡方程,进而阐释了这类体系中有效熵产生的统计内涵,初步揭示出内涨落和来自化学反应交联的外噪声的随机热力学效应.并通过对宏观扰动的随机模拟,在一定程度上分析了化学反应交联对体系宏观稳定性的影响

By using Novikov's Law and MSR theorem, both the effective master equation and effective entropy balance equation, generally valid for finite chemical reaction systems influenced by Gaussian white noises, have been established. It is shown that there are three kinds of conjugated stochastic forces and fluxes. A general expression of effective entropy production explicitly involving the contributions from both the internal fluctuations and the external noises is deduced. Furthermore, for the case of the non-macroscopic...

By using Novikov's Law and MSR theorem, both the effective master equation and effective entropy balance equation, generally valid for finite chemical reaction systems influenced by Gaussian white noises, have been established. It is shown that there are three kinds of conjugated stochastic forces and fluxes. A general expression of effective entropy production explicitly involving the contributions from both the internal fluctuations and the external noises is deduced. Furthermore, for the case of the non-macroscopic order noises,by means of the Kramers-Moyal expansion of the effective master equation, a stochastic formalism simulating the macroscopic stability criterion of nonequilibrium steady states in finite chemical reaction systems influenced by white noises is also established, and then an illustration quoting the simple case with additive noises shows the weakening effect of the external noises to the stability of chemical reaction systems.

通过分析噪声对跃迁概率的不同影响,借助Novikov定理及MSR理论,建立了受多源白噪声影响的有限化学反应体系的有效主方程及有效熵平衡方程,导出非平衡定态时这类噪声体系熵产生的一般表达式,揭示涨落熵产生的统计内涵及噪声贡献,并针对非宏观量级的外噪声,借助扰动按分布参数分离法及有效主方程的Kramers-Moyal展开,进一步对简单加合性噪声建立了非平衡定态宏观稳定性判据的随机模拟,论证了噪声对化学反应体系定态稳定性的弱化作用.

This paper begins with analyzing the distributing characteristic of the reading image frequency chart, partitioning the frequency chart, building area gray-degree model, ulteriorly shielding the entropy yawp and calculating the effective entropy, respectively realizes the threshold auto-setting. The experiment results show that the arithmetic can effectively solve the problem for multi-threshold auto-setting. ;;;
