摘要：

The surface reaction model of Ziff, Gulari, and Barshad (ZGB) is investigated on finite systems with ''hard'' oxygen boundary conditions. The rate of production of CO2 is calculated as a function of y and system size. When the rate of CO adsorption y is above the first-order transition value y2, the reactive region is found to extend into the system a distance xi which scales as (y-y2)-0.40 when y --> y2.
