双催化剂对A-B2类反应的最优构象
摘要:
在平面网格上将两个相邻格点定义为一个“超结构”，并在此基础上给出了一种新的元胞自动机模型用于模拟CO在α,β NMRD双催化剂表面的氧化反应.这里反应只在同一个超结构内发生，并以演化几率为参数，来控制超结构内反应物的反应过程.在模拟中，以平均反应速率最大对应的构象为最优构象,给出了以3×3网格为晶胞，α所占比例为1/9～8/9，及以4×4网格为晶胞α所占比例为1/16～15/16时的一系列α,β双催化剂的最优构象.

Optimum Configuration of Bicatalysts for A-B2 Reactions
Abstract:
A new Cellular automaton model for the bicatalytic CO＋O2 surface reaction is introduced by means of building oriented two-pointed "superstructure" in lattice.Reactions can only happen in superstructures.
We use reaction probability as variable to control reactions in superstructures.We use rate-per-α as variable to determine the optimum configuration for a series of α′s occupation from 1/9 to 8/9(3×3 lattice as unit) and from 1/16 to 15/16(4×4 lattice as unit).
