The objective of this project is to elucidate the mechanism for the bifurcation of chemical oscillations of B-Z reaction in relation with the instability of CSTR operation. Fe^<2+>-Fe^<3+> system as well as Ce^<3+>-Ce ^<4+> system are used as the metal catalyst. The residence time T was varied mainly as the bifurcation parameter. The volumetric capacity of the CSTR used is 30 ml. When T is sufficiently large, there do not appear any chemical oscillations owing to chemical equilibrium. On the other hand, there do not occur any oscillations owing to dynamical equilibrium of CSTR. At T = 21.7 min, there appear mixed oscillations with two different amplitudes. At T = 21.4 min, there does appear chemical chaos. At T = 16.0 min, however, there appear single-peak periodic oscillations again, which have a limit cycle trajectrory in phase space. At T 7.75 min, there appear regular oscillations, which have 8-shaped attractor in phase space. The time period of the oscillations tends to be lengthened with decreasing the residence time. The time period and amplitude tend to increase with increasing the feed concentration of bromide ion and with decreasing the feed concentration of malonic acid.

该项目的目的是阐明与 CSTR 操作不稳定性相关的 B-Z 反应化学振荡分叉机制。 Fe ^ 2+ -Fe ^ 3+ 体系以及Ce ^ 3+ -Ce ^ 4+ 体系用作金属催化剂。停留时间 T 主要随分叉参数变化。所使用的CSTR的容量为30ml。当T足够大时，由于化学平衡，不会出现任何化学振荡。另一方面，由于 CSTR 的动态平衡，不会发生任何振荡。在 T = 21.7 分钟时，出现两种不同幅度的混合振荡。在 T = 21.4 分钟时，确实出现了化学混乱。然而，在 T = 16.0 min 时，再次出现单峰周期性振荡，其在相空间中具有极限环轨迹。在T 7.75 min 时，出现规则振荡，相空间具有8 形吸引子。振荡的时间周期趋于随着停留时间的减少而延长。随着溴离子进料浓度的增加和丙二酸进料浓度的降低，时间段和幅度趋于增加。
