摘要 研究了外噪声对细胞内钙离子体系振荡的影响,结果表明外噪声可以在确定性体系不存在振荡的区域诱导出随机钙离子振荡。随着噪声强度的改变,振荡会在某一强度下显示最佳的行为,表明随机共振现象的出现。 The influence of external noise on calcium oscillation in a cell is investigated.It is shown that calcium oscillation is induced by external noise in deterministic steady state.With the variation of the noise intensity,the oscillation shows the best performance in certain intensity,implying the occurrence of stochastic resonance.
