摘要
利用一维扩散过程的奇点理论并结合能量包络的随机平均法，考查“隐藏在余维2分岔点之后”的同宿分岔系统受参激白噪声影响的分岔行为．
By virtue of the singular point theory of one-dimension diffusion process and the stochastic averaging approach of energy envelope, the bifurcation behavior of a homoclinic bifurcation system, which is in the presence of parametric white noise and is concealed behind a cedimension two bifurcation point, is investigated.
