摘要：

The oscillations of a linear triatomic molecule with the first atom driven at a constant velocity v are studied numerically. As v increases, we observe a sequence of transitions from quasiperiodicity to chaos, mode locking, and chaos, another mode locking, then to chaos before the atoms break off. The largest Lyapunov exponent does not increase linearly with the driven velocity. The mode-locking structure for the last onset to chaos has a universal fractal dimension 0.871 +/- 0.001 at a winding number far from the golden mean.
