| 摘 要： | 非统性化学反应现象（包括化学振荡、化学波和化学混饨等）的研究近二十年来进展较快，BZ反应＊、NADH氧化的生化反应＊及卤类化合物主导的其它反应体系［’－’］的混饨、双节律等复杂非线性现象不断被发现并得到不同程度的确证．无卤无机反应体系的复杂非线性现象未见报导，我们选择H202－KSCN－CllS04－N。OH无卤体系K7］进行探索，此反应在连续搅拌反应器（CSTR）和封闭反应器（batch）皆有振荡现象，在体系中加入鲁米诺（11J．－－－－n由产生发光振荡现象问，我们对这个反应体系的进一步研究发现复杂振荡（包括非周期过程）…

| Abstract: | Complex periodic oscillations which are associated with Farey sequences and sustained aperiodic oscillations (maybe chemical chaos) have been first observed in Hydrogen Peroalde-Potassium Thiocyanate-Cupric Sulfate System in a CSTR. When pH is high (generally at pH>9), oscillations in pH and Pt potential in solution are synchronous,and pH increases as Pt potential in solution increases; when pH is low (gernerally pH<9),oscillations in pH and Pt potential are antiphase. Birthymicity of two oscillations appears at a same condition. A simple explanation is discussed. |
