China's Yellow Sea and East China Sea continental shelf seabed has basically been at.

我国的黄海和东海的海底基本处于大陆架上。

"These undersea volcanoes lie within British seabed territory recognised by the United Nations," says Dr Copley.

As the seabed erosion rate decreases, the diapir shrinks gradually and disappears finally due to the erosion.

软弱层变形及刺穿对海洋工程设施危害极大。

After the river channel shifted, the discharging center of pressure was generated from the seabed erosion, on which the diapir came into being.

黄河口摆动后，海底快速冲刷，在最大冲刷中心也是最大压力释放中心刺穿体形成，随着海洋侵蚀速率减缓，刺穿作用将逐渐减弱，最终将被冲刷消亡。

So, a new method for calculating the seabed slope angle called the differential method is put forward.

为此，针对单波束测量提出了一种实用的海底倾斜角差分算法。

The results show the mineral taxa, morphological characteristics and the high contents of magnetite and dens revealed the multi-sources and near-derived features of the loess-like loess in Zhifu Island, and the main sources of loess are seabed plain, diluvium and residual sediments in the last glacial period, while thin sediments from Northwest inland desert are rare.

结果表明，芝罘岛黄土状黄土矿物种类、矿物形态特征、磁铁矿和岩屑的高含量等都揭示了黄土来源的多源性和近源性，末次冰期时的海底平原沉积物以及洪积、残积物是芝罘岛黄土状黄土的重要物源，而西北内陆沙漠吹来的细颗粒物质相对较少。

This is a very first bottom of the sea diorama I've made, having thought long and easy over the problem, encasement on 3 sides should give a good impression of under the waves, the diver with no bubbles was a disappointment, I asked and got several replies on this problem as to the colour of the seabed, so going with a mix of sand and mud, I thought this would cover most of the angles.

这是我做的最早的海底场景，考虑了很久，易于问题，三面装箱应该提供一个好的水下效果，潜水员没有气泡令人失望，在这个问题我询问并获得若干的答复，如海床的颜色，与之相配的沙子和淤泥，我认为这将涵盖了最多的角度。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。
