【摘要】 对于具备快、慢两种不同时间尺度的生物细胞内钙振荡的高维动力系统,应用非线性动力学分岔分析理论结合数值仿真,研究了参数变化时,钙离子浓度呈现出的不同类型的簇振荡模式。依据Izhikevich提出的分类判据,在Marhl和Haberichter等人提出的数学模型中得到了"点-环"型"sub Hopf-sub Hopf"和混沌两种簇振荡现象。更多还原

【Abstract】 Based on the calcium oscillatory model with fast and slow time scales, bifurcation analysis and numerical simulation are applied to study the different calcium oscillations as one important and amendable parameter varying. Based on the strategy proposed by Izhikevich, "Sub Hopf-Sub Hopf" bursting of "point-cycle" and chaotic bursting type in Marhl-Haberichter model are studied.更多还原
