摘要
证明了一类加保护的电子张弛振荡电路可以由一组不连续保守映象来描述 .因为系统映象的不连续性而导致映象具有不可逆性 ,使得这个不连续保守系统展示出非常特殊的“类耗散”行为 ,文中报道了在该系统中发现的规则类吸引子和混沌类吸引子 .
It is proved that electronic relaxation oscillators with over\|voltage protection could be described by a group of discontinuous conservative maps. The noninvertibility of the map induced by piece\|wise smooth property leads to a special behavior of the system, which may be called quasi\|dissipative property. The discovered regular and chaotic quasi\|attractors are reported.
