The Euler equations of incompressible and inviscidfluid are used for control equations of the stern flow field, and the propeller is computed by lift line theory.
选取了不可压缩无粘流体的欧拉运动微分方程作为尾流场的控制方程，螺旋桨则用升力线理论计算。

The resonant flow of an incompressible, inviscidfluid with surface tension on varying bottoms was researched. The effects of different bottoms on the nonlinear surface waves were analyzed.
Higher order waves generated by a moving source in a two-layer inviscid, incompressible fluid of finite depth with small density difference were studied.
