标题： Capillary-Gravity Waves on Depth-Dependent Currents: Consequences for the Wave Resistance

摘要： 我们从理论上研究了当流体中初始存在一个随深度变化的水流时，由一个小的二维扰动在水-空气界面产生的毛细重力波。 假设线性波理论，我们推导出在无粘流体情况下，扰动所经历的波阻力的一般表达式，该表达式是电流剖面的函数。 然后我们详细分析和讨论了在特定情况下的波阻力行为，即线性水流情况，这是某些风生水流的有效近似。 显示英文摘要

摘要： We study theoretically the capillary-gravity waves created at the water-air interface by a small two-dimensional perturbation when a depth-dependent current is initially present in the fluid. Assuming linear wave theory, we derive a general expression of the wave resistance experienced by the perturbation as a function of the current profile in the case of an inviscid fluid. We then analyze and discuss in details the behavior of the wave resistance in the particular case of a linear current, a valid approximation for some wind generated currents.
