水面

This is mainly caused by excellent absorption properties and an enormous amount of specific surface.

这主要是由于优良的吸收性能和大量的具体浮出水面。

The main clue of the paper is that in view of the danger and rapidness, taking practicable signal processing technology, sending torpedo information to acoustic countermeasure system rapidly and accurately.

本文研究工作的主线是针对鱼雷攻击的危险性和快速性，采取切实可行的信号处理方法，快速准确地向水面舰艇水声对抗系统提供鱼雷报警信息。

This paper analyzes the process of depth charge intercepting torpedo, establishes a model of ship evading acoustic homing torpedo, and obtains the evasive turning angle as evading torpedo in different torpedo alert areas by using Monte-Carlo method.

本文分析了水面舰艇使用悬浮式深弹拦截鱼雷过程，建立了舰艇使用悬浮式深弹时规避声自导鱼雷数学模型，采用蒙特卡洛法通过计算机仿真，得出了在不同的鱼雷报警区域内舰艇规避鱼雷时的规避转向角。

According to the operational application characters of rocket assisted torpedo, as well as the definition, applicable occasion, and implementing means of ship-to-air missile, ship-to-ship missile, and acoustic homing torpedo salvo, this paper analyses and achieves the definition and conception of rocket assisted torpedo salvo in order to improve the actual training and operation, and enhance the anti-submarine capability of surface formation.

针对火箭助飞鱼雷这一反潜利器，本文根据其作战使用特点，参考舰空、舰舰导弹及管装声自导鱼雷齐射的定义、使用时机和组织实施方法，分析了与实际训练和作战相契合的火箭助飞鱼雷齐射相应的定义和概念，对火箭助飞鱼雷的作战使用及发挥我方水面舰艇编队反潜作战能力具有重要意义。

The mission saw several landmarks in the history of the Chinese navy, said Rear Admiral Du Jingchen, commander of the fleet. It is the first time for the naval vessels, shipboard planes and Special Forces to combine together for a non-warfare mission. It is also the first time for the Chinese navy to cooperate with international navies for the same mission on the same waters.

据编队指挥员杜景臣少将称，在过去4个月的护航过程中，海军舰队开创了海军史上多项第一，如第一次组织水面舰艇、舰载机和特战队员多兵种跨洋执行非战事行动，以及第一次与多国海军在同一海域执行任务。

If you never leave the dock, you'll never have an enterprise to keep afloat.

如果你从没离开过甲板，你就永远不会有浮在水面的一个企业。

No, there is mechanical surface agitation of the water .

不。有一种使水面波动装置。

Ship's main mission is to provide the necessary surface fleet of regional air defense capabilities and commitment to anti-submarine, anti-ship and land attack support mission.

42级舰的主要使命是为水面舰艇编队提供必要的区域防空能力，并承担反潜、反舰攻击和对陆支援的任务。

Fleet to provide air defense and anti-submarine, surface ships and large-scale enemy at war, including large-scale combat aircraft.

提供舰队防空和反潜，与敌方大型水面舰艇交战，包括打击大型航空母舰的能力。

They placed an inflatable jacket around the wreck as it lay on the seabed. Then by filling the jacket with air we raised the wreck to the surface.

他们将一可充气的外盖套套住躺在海底的残骸，然后向套中充气，这样我们就能将残骸捞出水面。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
