BZ反应的耦合温度振荡(I)——BZ反应化学振荡的起振温度阈值

COUPLED TEMPERATURE OSCILLATION OF BELOUSOV ZHABOTINSKY REACTION(I) ——TEMPERATURE THRESHOLD OF THE BZ OSCILLATING REACTION

在理想恒温条件下，通过ＢＺ反应中各反应步骤活化能的分析，阐明了ＢＺ反应体系中间物浓度变量演化方程与温度的关系；根据线性稳定性分析法，确定了以温度Ｔ及模型参数ｈ（ＮａＢｒＯ３浓度为定值）为参数的ＢＺ反应振荡动力学分区，使ＢＺ反应振荡阈值的理论更加系统化．通过ＢＺ反应振荡温度阈值的研究。

The authors elucidates the temperature effects on the evolution of the intermediate concentrations in the perfect isothermal BZ reacting system,by analysis of the activation energy of the elementary steps.Using the analysis of linearized stability,it further gives the dynamic rigime of oscillatory behavior on the temperature model parameter plane under condition of constant bromate concentration.This work systematizes sthe oscillafion threshold theory of the BZ reaction.In addition,it predicates a new way to obtain information about the activation energies of the elementary steps,through the study on temperature threshold of the BZ oscillafing reaction.
