摘要

摘要: 本文研究了白噪声参数激励下的Hopf分叉系统的两次分叉行为.明确了由于噪声的介入而使得系统的分叉类型产生了实质性的改变并导致了分叉点的漂移.

Abstract: The present work is concerned with the behavior of the second bifurcation of aHopf bifurcation system excited by white-noise. It is found that the intervention ofnoises induces a drift of the bifurcation point along with the subtantial change inbifurcation type.
