迄今为止,化学振荡的研究主要限于描述物质浓度的振荡,有关热力学量的振荡报导极少.这可能是由于振荡机理(或模型)中的热力学量无法确定的缘故.我们采用将标准化学亲合势作为可调参数的方法,并依据非平衡态热力学理论中热力学量与物质的浓度关系,使得热力学量振荡的研究变为现实.本文用计算机数值计算,得出了开放系Brusseltor各元反应的反应速率、化学亲合势及体系熵产生随时间的变化行为,展示了它们的振荡特征。
Until now, the study of chemical oscillations has mainly been limited to the description of the oscillations of the material concentration, with very few reports on the amount of thermodynamic oscillations which may be due to the uncertainty of the amount of thermodynamics in the oscillating mechanism (or model) Potential as an adjustable parameter method and based on the relationship between the amount of thermodynamics and the concentration of matter in the theory of non-equilibrium thermodynamics, making the study of thermodynamic volume oscillation become a reality.In this paper, the Brusseltor open-system reaction The reaction rate, chemical affinity and entropy of the system change with time, showing their oscillation characteristics.
