摘要:

介绍由保面积映像不连续、不可逆耦合构成的"类耗散系统",并以两个系统为例介绍类耗散系统的主要性质.这样的系统中会出现规则或混沌的,能把外部的迭代吸引过来的"类吸引子",但迭代一旦到达类吸引子,又会展示典型的保守性运动.这类系统中可能出现"类V形阵发",在适当的参数改变时,还可以展示从典型的保守系统向近似于耗散系统的连续转变.更多的特异性质还有待于继续研究.

关键词: 保面积映像, 耗散系统, 保守系统, 吸引子, V型阵发

Abstract:

Introduces so-called "quasi-dissipative systems" and their main characteristics with two sample systems. In such systems regular or chaotic quasi-attractors may appear, which can attract the iterations outside. However, as soon as the iterations reach the quasi-attractors, they perform typical conservative motion. There can be "type V quasi-intermittency" in the systems. Also, when a suitable parameter changes the system can display a continuous transition from a typical conservative system to a system that is very similar to a dissipative one. More characteristic properties are being studied and will be reported soon.

Key words: area-preserving map, dissipative system, conservative system, attractor, type V intermittency
