一、引言周期性反应如H_2O_2分解,丙二酸的自催化反应,现在研究的已相当多了,G.Nicolis等已作了总结性报导。H-2O_2分解反应的特点系周期性放出O_2和碘浓度成周期性变化。丙二酸自催化反应的特点系log〔Ce~(4+)〕/〔Ce~(3+)〕和log〔Br~-〕和10g(B,.)成周期性变化 I. INTRODUCTION Periodic reactions such as H 2 O 2 decomposition and autocatalysis of malonic acid have been studied quite a bit now. G. Nicolis et al. Have made a summary report. The characteristic of H-2O 2 decomposition reaction is periodic release of O 2 and iodine concentration into periodic changes. The autocatalytic reaction of malonic acid is characterized by periodic changes of log 〔Ce ~ (4 +)〕 / [Ce ~ (3+)〕 and log 〔Br ~ -〕 and 10g
