通过几个实例的分析 ,说明二维映象中V型阵发的层流相所占据的相空间区域常常具有一维特征 .这些一维相空间区域对应于已经由边界碰撞分岔消失的周期点的“鬼魂”留下的一段稳定流形 .它们构成类似于一维映象中阵发发生后层流相迭代通过的“隧道” .隧道的开口有明确的位置 .V型阵发的湍流相所对应相空间区域具有二维特征 .解析讨论了这些特征的形成机制 .
The analysis of several examples shows that the phase space occupied by the laminar phase of the V-shaped burst in the two-dimensional image often has a one-dimensional characteristic.These one-dimensional phase-space regions correspond to the periods that have disappeared by the boundary collision bifurcation The “ghost” of the point leaves a steady stream of manifolds that form a “tunnel” that is similar to the passage of the laminar phase after a burst in a one-dimensional image. The opening of the tunnel has a definite position. The corresponding phase-space region has two-dimensional features, and the formation mechanism of these features is analyzed and discussed.
