【摘要】 本文利用实验中得到的电动势随时间变化的E-t图,研究了体系中Mn²⁺,Br^-离子浓度的振荡行为。发现二者在平面上随时间变化的轨迹不宜用二维的极限环理抡来解释,这说明描述体系的振荡行为的极限环至少是三维空间的一条闭轨线,并用xy函数记录仪,观察了极限环在平面上的投影线,探计了反应机理,并推测其模型。更多还原

【Abstract】 In this paper, the Mn2+ and Br- oscillating behaviour of the system were studied by using the E-t graphs, we find that both Mn2+ , Br- curves in the phase plane that can not be explained by limit cycle of two-dimensions. We used xy recorder, so that projections of limit cycles were got. The dimensions ofoscillating behaviour are not less than 3. We suggest the mechanism of reaction, and give a model as oregonator.更多还原
