海床

This physiographic framework is provisional and may be revised if better physiographic names are proposed.

东海大陆棚相当地宽，且其海床平坦，但局部有明显的地貌起伏，这是受到晚更新世海水面升降及弧后盆地张裂的火山活动影响。

Rocky Mountains. A similar approach is being used to analyze the producibility of natural gas hydrates – methane trapped in ice in arctic regions and beneath sea beds.

类似的做法正在被用来分析天然气水合物的可生产性-甲烷被困在北极地区和海床以下的冰里面。

For all we know, the ship may be just doing bottom profiling.

我们都知道，那船在做海床测绘。

Today enough soundings are available to enable a relief map of the Atlantic to be drawn and we know something of great variety of the sea-bed's topography .

今天测量术已经足可以描绘出大西洋的地貌图，并且我们知道辽阔的海床的一些地貌变化。

That is fraught with difficulties as there is no seabed agreement between the riparian states.

在沿岸的国家之间还没有海床协议的情况下，这是困难重重的。

Water table, the gravels and sands of the former river bed, and its sandbars, will be saturated

这里讲了一种特别的和上面原理一致的胆识小范围的情形，那就是扇形的坡面，河床，海床等。

In the Gulf of Mexico , trawlers ply back and forth year in year out , hauling vast nets that scarify the seabed and allow no time for plant and animal life to recover .

墨西哥湾的拖捞船年复一年地来来往往，拉着巨大的拖网，破坏了海床，甚至不给海洋动植物恢复的机会。

There were literally tens of thousands of these corallimorphs covering the sea floor

在一岩石上面，这里有大量的红综色海葵，成千上万的布在海床上

How far can the evidence observed on the sea floor support the existence of plate movements?

在多大程度上，海床的证动据可支持板块移的存在？

Debris falling out of the ship was strewn over a 1/2 mile across the sea floor.

沉船的残骸散开来在海床上铺了半英里。

I smile at your play with that little bit of a broken twig.

我微笑着看你玩那一段小小的树枝。

They may be produced for almost any shaft angle.

他们可能在制作中几乎任何一个轴角。
