摘要：

A chemical Turing instability resulting in steady spatial patterns is examined here when we superimpose a perturbatively small time periodic modulation on its control parameter. Results for both the modified instability threshold and the corresponding growth of the bifurcating solutions are explicitly obtained. In particular, quasiresonant effects originating significant stabilization or destabilization of the system, depending on the model parameters, are predicted for particular values of the forcing frequency. © 1990 American Institute of Physics.
