Interfacial processes as well as formation of dissipative structures have been suggested to play a key role in early pre-biotic evolutionary stages, mainly due to the ability of such processes to induce aggregation and spatial structuring. In this context we would like to draw attention to our recent findings regarding a remarkably wide collection of interfacial chemical reactions which form dissipative spatial structures. Three types of interfacial processes were found to yield this phenomenon: photochemical oxidations at liquid/air and liquid/liquid interfaces; gas/solution reactions; and reactions at membrane surfaces. The phenomenon we describe is the first major example of a network of chemical reactions that develop into macroscopic far-from-equilibrium concentration patterns.
界面过程以及耗散结构的形成被认为在早期生命起源前的进化阶段中起着关键作用，这主要是因为这些过程具有诱导聚集和空间结构化的能力。在此背景下，我们想提请注意我们最近关于形成耗散空间结构的大量界面化学反应的研究结果。发现有三种类型的界面过程会产生这种现象：液/气和液/液界面处的光化学氧化；气/溶液反应；以及膜表面的反应。我们所描述的现象是化学反应网络发展成宏观非平衡浓度模式的第一个主要例子。
