对均匀坡面上两层体系中凹陷内孤立波的浅化问题进行了室内实验研究。单个孤立波的浅化导致波浪破碎，并产生沿斜坡向上传播的多个湍流涌浪或团注。强烈的垂直混合发生在破裂位置近岸的任何地方。描述了破碎机和推进机的运动学，并找到了破碎机的判据。对断裂的能量学进行了研究。在所考察的参数范围内，在断点近岸的第一模波动损失的能量中，有15(±5)%进入垂直混合。
Laboratory experiments have been conducted to study the shoaling of internal solitary waves of depression in a two-layer system on a uniform slope. The shoaling of a single solitary wave results in wave breaking and the production of multiple turbulent surges, or boluses, which propagate up the slope. Significant vertical mixing occurs everywhere inshore of the breaking location. The kinematics of the breaking and bolus runup are described and a breaking criterion is found. The energetics of the breaking are investigated. Over the range of parameters examined, 15 (±5) % of the energy lost from first-mode wave motion inshore of the break point goes into vertical mixing.
