| 摘 要： | 我们从单摆运动规律入手论述非线性动力学.有关非线性动力学的一些概念如混沌、吸引子、分形、Lyapunov 指数和自组织临界性等都作了讨论,并且评论了混沌和同宿轨道,同宿轨道和孤波,孤波和湍流.湍流和自组织临界性之间的关系.这些为进一步研究非线性动力学提供了线索.

| Abstract: | In this paper,nonlinear Dynamics begin with the motion laws of the pendulum.The principal con-cepts of nonlinear Dynamics such as chaos,attractor,Lyapunov exponent,fractal and sclf-organizedcriticality are discussed.The relations between different terms are reviewed:Chaos-homoclinio orbit-solitary wave-turbulence-self-organized criticality.These provide clues for further study of nonlinear Dynamics. |
