非理想性对BZ反应体系热力学性质的影响

作者在对非理想BZ反应体系动力学行为研究的基础上，进一步研究了非理想性对BZ反应体系热力学性质的影响．通过非平衡态热力学理论分析，并根据实测浓度振荡变化时序数据进行计算，结果表明：非理想BZ反应体系中出现的双峰振荡较单峰振荡具有更大的熵产生周期平均值，表明维持多环极限环的时间自组织行为比单环极限环需要更大的熵流，而且惰性电解质的加入，使这种差别进一步扩大．

Influence of Nonideality on Thermodynamical Properties of BZ Reaction System

Based on the research of dynamic behavior of the nonideal BZ reaction system, the influence of nonideality on thermodynamical properties of the BZ reaction system is further analyzed. According to the nonequilibrium thermodynamic theory, as well as the experimental time-series data of the concentration oscillation, it is concluded that the two-peak oscillation possesses a larger periodical average of entropy production than the one-peak oscillation in the nonideal BZ reaction system. The larger entropy flux is needed to keep the temporal self-organization of the limit multi-cycle than that for the limit mono-cycle in the nonideal BZ reaction system. Moreover the additive inert electrolyte in thermodynamic behavior further increases this kind of difference.
