考虑了非简谐链中类Kac-Baker长程相互作用势的影响。短程和长程相互作用的相互作用导致存在两种类型的孤子的特征不同的宽度为两个速度区域分开的间隙。低速分支存在直到最大临界速度，其中形状达到峰状形式。在高速分支中，我们使用多尺度分析，因为两个不同的尺度是重要的。
We considered the effect of a Kac-Baker-like long-range interaction potential in an anharmonic chain. The interplay of short-and long-range interactions leads to the existence of two types of solitons with characteristically different widths for two velocity regions separated by a gap. The low-velocity branch exists up to a maximum critical velocity where the shape reaches a crestlike form. In the high-velocity branch we used multiple scale analysis since two different scales are important.
