相同模式内弧立波的强斜相互作用

Strongly oblique Interactions between Internal Solitary Waves with the Same Mode

水文讨论分层流体中相同模式向孤立波的强斜相互作用，包括浅流体情形和深流体情形．采用Lazrange描述方法，发现在浅流体情形相互作用由KP方程描述；在深流体情形相互作用由二维的中等长波方程描述：在无限深情形相互作用由二维的BO方程描述．

In this paper, by using the Lagrangian coordinates, the strongly oblique interactions between solitary waves with the same mode in a stratified fluid are discussed, which includes the shallow fluid case and 'deep fluid case. It is found that the interactions are described by the KP equation for the shallow fluid case, the two-dimensional intermediate long wave equation (2D-LW equation )for the deep fluid case and the two-dimensional BO equation (2D-BO equation)for the infinite deep fluid case.
