摘 要: 报道了Na2SO4稀溶液对邻菲啰啉亚铁离子(ferroin)催化的B-Z体系动力学行为的影响.结果表明,当Na2SO4溶液浓度大于0.30 mol.L-1时,体系呈现周期性振荡,而低于此临界值时,规则的周期性振荡将转化为混沌或拟周期振荡.此外,对其机理进行了初步探讨. The effect of Na2SO4 diluted-solution on the dynamic behavior of the ferroin-catalyzed B-Z system is reported in the present paper.Results indicate that the regular oscillation is observed only at the concentration of Na2SO4 solution being more than 0.30 mol·L^-1,otherwise,the periodic oscillation can be changed into chaos or quasi-periodicity oscillation.In addition,the perturbation mechanism of Na2SO4 solution to the B-Z system is discussed in brief.
