通过直接数值时间推进，采用两种不同的计算方法，我们跟踪了当初始能量超过相同波长的最高能量周期波时，驻留重力波在深水表面上的发展。文中详细研究了运动的两个方面：一是最大表面倾角接近45°瞬间的波型序列；二是自由面上形成尖端的条件。当一个尖端形成时，它可以垂直落入波谷，包围“气泡”。
By direct numerical time stepping, using two different methods of calculation, we follow the development of a standing gravity wave on the surface of deep water when it is given an initial energy exceeding that of the most energetic periodic wave of the same wavelength. Two aspects of the motion are studied in detail: the sequence of wave profiles close to the instant when the maximum surface slope angle is close to 45° and, second, the conditions under which a sharp cusp is formed at the free surface. When a cusp is formed, it can fall vertically into the wave trough, enclosing “bubbles of air.”
