本文综述了在反应-扩散斑图研究中反应器的进展情况。直到20世纪80十年代,人们主要在培养皿中研究封闭体系的化学波。为了研究体系在远离平衡态条件下的复杂时空动力学行为,近20年来人们设计出许多新颖的空间开放反应器(continuously fed unstirred reactor,CFUR),如单边进料反应器(one sidefed reactor,OSFR)、双边进料反应器、圆盘形凝胶、圆环形凝胶反应器以及Couette反应器等。反应介质主要为各种凝胶、微孔膜、离子交换树脂以及中孔玻璃。空间开放反应器的设计和发展极大地促进了化学斑图动力学的发展。同时,讨论了反应-扩散斑图反应器结构设计遇到的困难如气泡和三维效应,并且对反应器设计与斑图研究未来发展方向进行了探讨。
This article reviews the progress of reactors in reaction-diffusion pattern studies. Until the 1980s, people mainly studied the closed-system chemical wave in petri dishes. In order to study the complex space-time dynamic behavior of the system far away from the equilibrium state, many novel continuous fed unstirred reactors (CFURs) have been designed in recent 20 years, such as one sidefed reactor OSFR), bilateral feed reactors, disc gels, circular gel reactors, Couette reactors and the like. The reaction medium is mainly all kinds of gel, microporous membrane, ion exchange resin and mesoporous glass. The design and development of space open reactor has greatly promoted the development of chemical motif kinetics. At the same time, the difficulties encountered in the structure design of reaction-diffusion speckle reactors, such as bubbles and three-dimensional effects, were discussed. The future development of reactor design and pattern research was also discussed.
