在此简讯中,我们用类似力学中处理单摆问题的方法,对一个简单模型导出了无公度相的多谐调制解。它在高温端退化为单谐调制;它在低温端转化为扭折解。它的基波波矢随温度而单调地下降,与实验观察到的现象一致。In this letter, we derive a multi-harmonic modulation solution of the incommensurate phase of a sinple model by a method like that used to solve pendulum problem in mechanics. This solution reduces to single-harmonic modulatioi at the of high temperature limit and transforms into kink solution at the of low temperature limit. The basic wave-vector decreases monotonously with temperature as observed in experiment.
