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。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.
