摘　　要：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。A review of recent progress in the reactor for reaction-diffusion pattern is presented.Up to the 1980s,chemical waves for the closed systems were studied mainly in Petri dish;And in recent two decades,various novel spatially extended open reactors（CFUR）are designed for investigating the asymptotic behaviors and the characteristics of phase transition,such as one side fed reactor（OSFR）,two side fed reactor,disc gel reactor,annular gel reactor and Couette reactor,etc.The reaction media are mainly gels,membranes,ion exchange resins and mesoporous glasses.As a result,the advances of reactor design have greatly promoted the deve-lopment of pattern formation.Furthermore,the difficulties encountered,such as gas-bubble and three-dimension effect for two dimension reaction-diffusion patterns,are discussed.The future directions of reactor design and pattern formation are proposed.
