文中还就流动的非线性对物体的波浪扰动力和自由面波形的影响进行了讨论。

The effect of the nonlinearity on total wave exciting force and wave contour is discussed.

作者给出了计算波浪扰动力的公式，使得在时域中有航速船舶波浪扰动力的计算，可以用辐射势和入射波势来表示，而不须求解绕射势。

A proposed "D. Z. Z. formula" for computing wave exciting forces is presented, therefore the exciting forces in time-domain can be given without computing the diffraction potential.

如果某种扰动(如爆炸)只影响一个小的地区，则波浪离开该点(扰动源)非常象水波离开石子入水处。

If the disturbance, such as an explosion, affects only a small area, the waves will move away from that point, much as the waves move away from our pebble.
