摘要: 通过数值模拟对3分子自催化反应A+2X?3X在一维和二维介质中的动力学行为进行了研究。发现在一维和二维情形下,如果施以不同的微观反应规则,该反应的渐近行为既可能偏离经典化学反应动力学(平均场理论)所预言的平衡极限行为,也可能与之一致。

Abstract: The dynamic behavior of the trimolecular autocatalytic reaction A+2X?3Xin one and two dimensions is studied by numerical simulations.It is found that the asymptotic behvior of the reaction can be, depending on the microscopic reaction rules, quite different from or the same as the equilibrium limit predicted by classical chemical kinetics(mean-fieldtheory)in both one and two dimensions.
