报导了BrO3--Ce3+-H2SO4-水杨酸-丙酮体系的振荡行为及其一些影响因素,并求出其在26~47℃温度范围内诱导期的表观活化能[1],及其在0.03~0.1mol.L-1浓度范围内的变化规律,并推测其可能的诱导期机理及振荡机理。

This paper reports the oscillating behavior in the oscillating system of BrO3^--Ce^3＋-H2SO4- Salicylic Acid-Acetone and the effect of some factors. According to Arrhenius equation, the apparent activation energy of the oscillatary induction period of this system are obtain within temperature range of 2：6 47℃. And proposing the likely principle of the oscillatary induction period and oscillation period
