摘要：

This paper illustrates the possibility, in simple loaded string models, of trapping most of the system energy in a single degree of freedom for very long times, demonstrating in particular that the robustness of the trapping is enhanced by increasing the connectance of the system, that is, the extent to which many degrees of freedom are coupled directly by the interaction Hamiltonian and/or the strength of the couplings.
