摘要
A simple two-component irreversible surface reaction model introduced by Ziff, Gulari, and Barshad has been studied using computer simulations. The model has a second-order kinetic phase transition. We have determined some of the critical exponents and find that the model belongs to the universality class of Reggeon field theory and directed percolation. © 1990 The American Physical Society.
