摘要：

A simple model is used to describe the motion of a chain of anharmonically coupled harmonic oscillators whose frequencies are in s : 1 resonance, or in which combination resonances occur. It is shown that stable soliton-like excitations exist. Exact quantum states, approximate classical solutions, and numerical simulations of the classical equations are presented.
