摘要：

Nonlinear waves in a one-dimensional periodic system are investigated. If the system is linearized, it has Bloch type solutions. It is shown that envelopes of the Bloch wave obey the nonlinear Schrodinger equation. Therefore, soliton propagations are observed in the system. Our method is applicable to many nonlinear periodic systems.
