But actually to get the right wave dynamics, you have to use a different scaling which is based on the Froude number.

但实际上， 为了获得正确的波浪动力学，您必须使用基于弗劳德数的不同缩放比例。

The first part of the equation rediscovered a bit of existing theory: it is an approximation of a well-known equation in wave dynamics.

方程的第一部分重新发现了一些现有理论：它是波浪动力学中众所周知的方程的近似值。
