浅水船波的近似寻求有效的临界速度U =（gh）1/2附近。对于足够薄的物体（支柱或船舶），控制方程是色散的。给出了对所有F2 ≤ O（1）都有效的简单解析解。随着厚度的增加，也会出现非线性。本文讨论了一种适用于稍超临界速度下尖头半体的孤子解。
Approximations for shallow-water ship waves are sought which are valid near the critical speed U = (gh)1/2. For sufficiently thin bodies (struts or ships) the governing equation is dispersive. Simple analytic solutions are given which are valid for all F2 ≤ O(1). As the thickness increases, nonlinearity also enters. A soliton solution is discussed which applies to a sharp-nosed half-body at slightly supercritical speed.
