电化学体系中非连续型振荡的诱发
THE INDUCEMENT OF RELAXATION ELECTROCHEMICAL OSCILLATION
【摘要】 根据非连续型振荡与慢流型、双稳态现象之间的内在联系,讨论了演化机制可出现多定态分支的电极反应体系,因外控状态参量慢变化导致非连续型电化学振荡的可能性.模型研究表明,适当的外电路阻抗或反应体系温度控制的热补偿机制的存在,可能诱发该类振荡,从而为抑制或诱发利用该类振荡提供了一条可能的途径.
【Abstract】 According to the relationship among the folded show mainfold,bistability and relaxation oscillation,to a electrochemical system in which bistability could be found,it is discussed that the possibility of appearance of the relaxation oscillation induced by a externally controlled parameter changes slow.It is turned out that the relaxation electrochemical oscillation could be induced along two approaches:proper arrangement of external electric circuit or suitable temperature controlling of heat compensation type,which is useful to the inducement or inhibition of electrochemical oscillation in experiment.
【Key words】 relaxation electrochemical oscillation; folded slow mainfold; external electric circuit; temperature controlling of heat compensation;
