在水下

Both push the limits of human survival at extreme depths: one using sophisticated technology and the other just a single breath. World-class divers Dave Apperley, Pete Mesley and Tim Cashman form a team to explore the wreck of RMS Niagara, a luxury liner sunk by a German mine in 1940. For over 60 years it has remained submerged in nearly 400 feet (120 metres) of water off the northern tip of New Zealand.

连白痴都能潜到水下一百米的沉船处，但若想安全地回到水面，就要靠技术了，在这个陌生的环境，这些潜水者寻找著世上最深的沉船之一，他们将用上足以媲美太空装备的科技，这可说是星舰迷航记症侯群，一心探索未知的领域，但有些人则很排斥水下呼吸器，只凭一口气潜到深海。

The eastern Laizhou Bay is an important potential area of littoral placer gold deposits of China, in Which both eluvial-deluvial and alluvial placer gold deposits are found. And placer gold anomaly is discovered in the littoral sand barrier, beach, subaqueous bar, subaqueous estuarine delta, seawater shallower than 14m, ancient lagoon, ancient alluvial layers and ancient coastline.

To solve the difficult depiction about the underwater counterwork system's static structure and dynamic process by traditional model at one time, and to meet the requirements of modeling for layering and extension, the model based on Object Petri Net was proposed.

针对通常的模型不能同时描述水下对抗系统的静态结构和动态过程，而且在层次化、可扩充性等方面也不能满足建模需求的问题，采用对象Petri网建立了水下对抗系统的模型。

Two methods of correlation of parasequence are put forward in fan delta and near shore sub-water fan sedimentary environment.

提出了在扇三角洲和近岸水下扇沉积环境中沿物源方向的相序递变对比法和垂直物源方向的侵蚀叠置对比法2种准层序对比模式以及在扇三角洲沉积环境中沿物源方向的扇三角洲前缘亚环境中的层组相变对比模式和近岸水下扇环境中叠置砂体对比模式、相变对比模式、薄砂层对比模式、相似渐变等5种层组对比模式。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

The model of mine's trajectory is built,and the model of wallop is built.Then the underwater trajectory of the airdropped mine is simulated by Matlab/Simulink.At last,This paper gets the result of simulation and analysis.

在建立了六自由度的水雷水下弹道数学模型和水雷入水击水力计算的数学模型基础上，通过实例对水雷的水下弹道在Matlab/Simulink环境下进行了仿真计算，最后给出相应的仿真结果和分析。

Herakleion and Menouthis were rich and proud cities until something reduced them to rubble and buried them in the mud beneath 30 feet of sea water, French underwater explorer Franck Goddio said at the American Geophysical Union conference

法国水下探险家Franck Goddio在美国地球物理联合会大会上说，一些不明物质使Herakleion城和Menouthis城分化为碎石并被埋到35英尺深的水下，在这之前这两座城市一直十分富足并让人引以为荣的。
