中文摘要：

针对一类描述钙离子振荡行为的生物数学模型,讨论两种类型钙振荡的三耦合生物细胞系统在链式与环式连接情况下的同步问题。通过分析和数值模拟,进一步说明链式耦合所需的临界值要大于环式耦合所需的临界值,即链式耦合往往需要更大的临界值才能达到系统的同步状态。

英文摘要：

The synchronizations in chain and ring connections related to three coupled systems are investigated.It is concluded that the criteria value in the chain connection is bigger than that in the ring connection to obtain synchronization in our analysis and simulations.
