KIO_3-H_2O_2-CH_2(COOH)_2-MnSO_4-HCIO_4反应系(简称B-R反应)在0.12~0.20M酸度范围内会出现三种颜色交替的双周期振荡,本文探讨了实验条件和反应机理。
The KIO_3-H_2O_2-CH_2 (COOH) _2-MnSO_4-HCIO_4 reaction system (B-R reaction) shows three-color alternating two-cycle oscillations in the acidity range of 0.12-0.20 M. The experimental conditions and reaction mechanism are discussed in this paper.
