一个电张弛振子中的瞬态激变

Crisis of transient chaos in an electronic relaxation oscillator

报道一例映孔导致激变后发生的奇异排斥子的拓扑突变 .这种突变以其分数维的突变为标志 ,并引起激变后长混沌瞬态运动行为的突变 。

A sudden topological change of a strange repeller happened after a hole-induced crisis is reported. This change is signified by the sudden change of its fractal dimension, and induces a sudden change of the behaviour of the long chaotic transient motion after the crisis, therefore it should be of importance in both basic theory and practice.
