In order to explore the factors affecting health evolution of knowledge-based enterprise organism,the modeling theory of cellular automata is adopted for analyzing the interactions between core intelligent units,sustaining intelligent units and dynamic environments.

By adding two layers of rods in the absorber, which makes flue gas distributes uniformly and forms primary turbulence zone, the absorber which have double absorption units can gain higher unit absorption efficiency , reduce L/G by 15% when gain equal desulfurization efficiency and reduce spraying nozzles by 20% and volume of sump by 20%.
