摘要：
This paper considers the synchronization dynamics in a ring of four mutually coupled biological systems described by coupled Van den Pot oscillators. The coupling parameter are non-identical between oscillators. The stability boundaries of the process are first evaluated without the influence of the local injection using the eigenvalues properties and the fourth-order Range-Kutta algorithm. The effects of a locally injected trajectory oil the stability boundaries of the synchronized states are performed using numerical simulations. In both cases, the stability boundaries and the main dynamical states are reported on the stability maps in the (K-1,K-2) plane. (C) 2006 Elsevier B.V. All rights reserved.
