| 摘 要： | 本文从拓扑熵、信息熵和Lyapunov指数的定义出发,得到了二维保面积映射时上述三个物理量之间的关系式;通过计算映射的运动轨道的Lyapunov指数,研究了二维保面积映射的拓扑熵随不可积参数变化的规律。

| Abstract: | According to the thrce definitions: the topological entropy, the metric entropy and the Lyapunov exponent, we get the general relations among them in two-dimensional (2D) area-preserving maps. With calculating the Lyapunov exponent of motive orbits of these maps, we study topological entropy's varying law as the stochastic parameter. |
