摘　　要：以酒石酸和葡萄糖混合物的双组份有机物作为B-Z化学振荡反应底物,在KBrO3-MnSO4-H2SO4-丙酮环境中进行化学振荡反应.通过研究确定该双组份有机底物的振荡体系出现化学振荡现象的各反应物的有效浓度范围,并系统地研究和讨论影响化学振荡的诱导期、周期、振幅、图形和寿命等诸多因素.提供化学振荡现象的实验依据,推断化学反应的过程,建立化学振荡反应的模型,为B-Z化学振荡反应体系增添新的内容.This paper presents a study of the concentration range of reactants of oscillation reaction in Tartaric acid-Glucose-KBrO3-MnSO4-H2SO4-Propanone system. It has set up a new B-Z reaction system with a typical oscillating wave . Effects of many factors on the oscillation have been examined. The period and preoscillatory time as function of the initial concentration of each reaction have been studied. The relationship equation between period and concentration and the apparent activation energy have been got .The oscillation reaction model and reaction mechanism have been established. It is composed of produced Br2, used up Br2 and Mn2+ catalysis unit.
