摘要在ZGB模型的基础上 ,我们提出一个ZGB扩散模型 .该模型包括了O和CO的扩散 ,消除了二级相变点 .实际上 ,消除二级相变点的关键步骤是引进了O的扩散 .O的扩散几率大约为 0 2 5左右时二级相变点消失 . We introduce a diffusion model that is based on the ZGB model.This model including diffusion of O and CO eliminates the second-order phase transition.In fact the key step to remove the second-order phase transition is the introduction of O-Diffusion.The second-order phase transition can be removed when the diffusion-probability of O is Small(0.25 or so).
