化学体系对外冲击响应的一般表达式

General Expression for the Chemical System Response to External Impact

B. Zilbergleyt

摘要:

本文给出了离散化学平衡热力学中化学体系状态基本图的修正。它将两种以前发现的基本地图类型结合在一起,涵盖了更广泛的情况,使我们能够获得更详细的图片,并更深入地了解一般化学系统对外部影响的反应。在这项工作中修改的一般表达式允许在响应处理中有更大的灵活性。图的解决方案,分岔图,包含单稳态热力学分支之前和双稳态区域后的分岔点。在静态图上,第一个区域由两个区域组成-真正的热力学平衡和开放平衡;第一个区域在动态图上被跳过。在双稳态区,系统应力由于外界冲击的进一步增大而通过混沌振荡释放,并被两个分岔子分支所包围。现在,对应于修正图的分叉图基本上更接近于某些实验图,例如,在电化学系统的实验中获得的。

英文摘要:

The paper presents amended basic map of states of chemical systems in discrete thermodynamics of chemical equilibria. Uniting two previously found basic map types in one and covering a wider range of situations, it allows us to obtain more detailed pictures and deeper understanding of what is the general chemical system response to the external impact. Amended in this work general expression allows for more flexibility in the response treatment. Graphical solutions to the map, bifurcation diagrams, contain the monostable thermodynamic branch prior to and the bi-stable area after the bifurcation point. On the static diagrams the first consists of two areas - true thermodynamic equilibrium and open equilibrium; the first area is skipped on the dynamic diagrams. In the bi-stable area, the system stresses, caused by further increase of the external impact, discharge themselves through chaotic oscillations, enveloped by two bifurcation sub-branches. Now bifurcation diagrams, corresponding to the amended map, are essentially closer to some experimental graphs, obtained, for instance, in experiments with electrochemical systems.
