摘要：

Spatial reactors allow the study of the true asymptotic states of dissipative structures in autocatalytic chemical systems in solution. They have permitted the experimental discovery of genuine Turing patterns. However, when reactions at work exhibit bistability between homogeneous steady states in a continuously stirred tank reactor, Turing structures remain elusive. A reason may lie in the existence for such reactions of the phenomenon of spatial bistability. A simple model for this effect is discussed here. (C) 2004 Wiley Periodicals, Inc.
