wave trough

In this paper, flume experiments are carried out to observe the sliding course of gentle-slope seabed, which exhibits as local superficial soil body, acted upon by the shearing actions of wave peak and wave trough, sliding downwards to form sheet flow.

论文研究利用水槽试验手段，观察得到缓坡海底滑动过程，表现为浅表局部软弱土体在波浪波峰波谷的剪切作用下发生成层运动并向深处发展的滑动；

As the wave bore down on us, the trough deepened.

当波涛向我们压来时, 波谷加深了.

The author provides a computation pattern of the celerity of wave crest and wave trough ( Vc, Vt), and the influenced distance of unsteady flow ( S).

提出水位变化幅度（△H），波峰、波谷传递速度（V峰、V谷），以及不稳定流波及其距离（S）的计算模式。

A sprinter's greater visibility is also assisted by the bow wave being bigger and the following trough being deeper.

游的快的运动员的可见度也得益于前面更大的涡流和其后的更深的波谷。

As wave bore down on us the trough deepened.

当波涛向我们压来时波谷加深了.

Tow sediment wave fields are developed in a depth zone of about 1 000 1 100m in the north eastern Rockall Trough.

北大西洋洛克尔海槽东北部水深约1000～1000m处有两个大型沉积物波发育区。

Sedimentary structures are mainly massive bedding, large trough cross bedding and oblique bedding with few parallel bedding, wave bedding and horizotal bedding;

沉积构造以块状层理、大型槽状交错层理和斜层理为主，见平行层理、波状层理和极少量的水平层理。
