摘要

对洛伦兹方程进行了数值研究。结果表明,洛伦兹奇异吸引子可以包括稳定不动点附近的吸引域或实时吸引子,以及与不动点之间的跳跃有关的瞬态集或导体。在洛伦兹方程的每个稳定不动点附近的近周期稳定局部轨道长序列是洛伦兹吸引子的实时吸引子。揭示了这些局部轨道序列的运动规律。发现了三个通用瞬变过程的主曲线,它们代表了洛伦兹吸引子的所有长序列的局部轨道。发现洛伦兹吸引子的导体可以用洛伦兹方程定义的3个时间变量的近次谐波瞬态过程来表示。

Numerical estimates of local and global motions of the Lorenz attractor
The Lorenz equations are studied numerically. It is shown that the Lorenz strange attractor can comprise attraction domains, or real-time attractors in the vicinity of a stable fixed point, and transient sets or conductors, which are related to jumps between the fixed points. It has been found that long sequences of nearly periodic stable local orbits near each stable fixed point of the Lorenz equations are real-time attractors for the Lorenz attractor. The laws of motion are revealed for these sequences of local orbits. The backbone curves are found for three universal transient processes, which represent all long sequences of local orbits of the Lorenz attractor. It has been found that the conductors of the Lorenz attractor are represented by nearly subharmonic transient process for 3 time-variables defined by the Lorenz equations.
