摘要：

We investigate the percolation properties of a two-state (occupied-empty) cellular automaton, where at each time step a cluster of occupied sites is removed and the same number of randomly chosen empty sites is occupied again. We find a finite region of critical behavior, formation of synchronized stripes, additional phase transitions, as well as violation of the usual finite-size scaling and hyperscaling relations, phenomena that are very different from conventional percolation systems. We explain the mechanisms behind all these phenomena using computer simulations and analytic arguments.
