摘　　要：在一类以冲击振子为背景的二维分段连续映象模型中观察到由周期运动向混沌转变的V型阵发道路.它具有两个特点:首先在使用作者提出的“穿越数”来描述周期轨道时,在穿越数-参数平面上可以观察到系统进入混沌之前展示的V型阵发前奏锁相阶梯,这个阶梯常常同时包含类似传统魔梯和类似多重魔梯的结构;其次所观察到的锁相阶梯之后出现的混沌吸引子都是系统函数不连续边界象集的归宿。Type V intermittency is found to exist widely in a kind of two-dimensional maps with a background of impact oscillators. It has two characteristics. Firstly, the prelude phase-locking staircase to type V intermittency before entering chaos includes the traditional-like and multiple-like devil's staircase structures; secondly, the chaotic attractor appearing after the staircase is always the end-results of the image set of the discontinuous borderline.
