Ensemble Simulation Study of a Chaos Model

Abstract:
The mesoscopic dynamics of a chemical chaos model was studied by stochastic simulations. Ensemble simulations of the model showed that there are intensive intrinsic fluctuations in the unstable motion. However, due to the globally stable character of deterministic chaos, the ensemble points were limited to distribute overall the chaotic attractor. Furthermore, individual simulation runs keep quantitative character of the deterministic chaos.

摘要:
用随机模拟方法研究了化学混沌模型的介观动力学。对该混沌模型的系综模拟发现,在这种不稳定运动中存在强烈的内部涨落,然而由于混沌运动整体上的稳定性,使得系综中的代表点被限制在混沌吸引子上,并且单个代表点形成的随机轨道很好地保持了确定性混沌吸引子的基本特征。
