摘要：

We have experimentally studied the transition to chaos in a quasi-one-dimensional chain of nonlinear coupled oscillators, with periodic boundary conditions. We show that as long as the dynamics are not chaotic, this transition follows an unusual scenario: the period doubling of a T2 torus. During this scenario all oscillators remain in phase. When the chain of oscillators bifurcates to chaos, it loses its spatial homogeneity and localized wave holes randomly propagate along the chain.
