深海底的

The cuvier's beaked whales dive deep into the ocean in search of food .

居维叶突吻鲸要潜到很深的海底进行捕食，当这些鲸鱼捕食的时候，它们发出的声纳信号遇到物体会反射给鲸鱼，这个过程称作声纳定位。

So far, these are the only animals scientists know of that could live in the deep undersea world.

到目前为止这些动物是迄今位置科学家所知道的唯一的可以生活在这么深的海底世界的动物！

Multi-beam Bathymetric System, which integrating new and high technology, is the most advanced bathymetric technique in the world right now.

多波束测深系统是当代高新技术的集成，是世界上目前进行水深测量最先进的手段，其特点在于用它可以对海底地形进行全覆盖无遗漏的测量，精度高、效率快。

Yet vast areas of the Pacific are unmapped and the Indian Ocean has hardly been touched. We know that several depressions in the floor are deeper than Mt.

我们已经知道有几个海床坑处的深度高于珠穆朗玛峰的高度，但是我们不能确定我们已经找到了海底最深的地方。

At the same time, however, technology also enabled fishermen to reach far deeper than ever before, into areas where bottom trawls can destroy in minutes what has taken nature hundreds in some cases thousands of years to build.

同时，技术的发展也使渔民可以到达从前不能到达的更深的地方进行海底拖网捕捞。这种捕捞会在几分钟内毁灭掉大自然几百年甚至上千年才能形成的一切。

Because plants can't grow at such depth, some animals adapted to survive by breaking down meat fin or even oil and in the waters of the Antactic, scientists discovered the Osedax - the region's first known whale bone eating worms.

但植物在如此深的海底无法生长，所以一些生物已经适应了靠吃一些小的东西，甚至是大西洋里的油状物质为生。而且科学家发现了，O，是该水域中第一已知的靠吃虫为生的生物。

Ballard's small titanium subs and rovers, with cameras that could dive to bone-crushing depths of 12,000 feet, finally gave the world its first glimpse of the sunken ship, and the gash that ultimately spelled its doom.

90年前，当泰坦尼克号从英国南安普敦出发时，被认为是永不会沉没的。但是在1912年4月14日，它却在自己的处女航中碰上了冰山，沉没在北大西洋的2英里深的海底里。

Researchers used cell-phone-like tracking devices, for example, to record the Arctic migration of narwhals, a whale with a long twisted tooth, and remotely operated submersible s to reach several kilometers down into the oceans to study delicate marine animals that are impossible to collect.

研究员们用一种类似于微型电话的探测器来追逐，比方说，可用来追踪有一个弯曲的大牙齿北极独角鲸的迁移。遥控潜水器到达数千米深的海底去研究那些微妙的不容易追踪的生物。

The device includes a drill spigot inserting into the marebase sand layer through the upper cover soil layer, there sets air inlet, sand discharging pipe and vibration connecting pipe in the drill spigot; there sets a sand absorption head on the bottom of the air inlet and sand discharging pipe; the bottom of the vibration connecting pipe connects with the vibration head; the sand absorption head is made up of a centre cavity, ring cavity and sand absorption pipe.

该装置包括一穿透上部覆盖土层插入到海底深埋砂土层的钻孔套管，在钻孔套管内，设有进气管、排砂管和振动连接管；进气管和排砂管的下端连接一个吸砂头；振动连接管的下端连接振动头；吸砂头由一中心腔室、环状腔体和吸砂管构成。
