在海上

This method is based on the Snell law of acoustic propagation in water. Different velocity gradients among linear layers in water are utilized to draw the sound ray chart, and a mathematical model of the geometric operational range is built. Furthermore, the geometric homing range is predicted with sound ray density, a prediction system of geometric operational range for acoustic homing torpedo is designed and the function of the system is realized through a system software. The sea trial demonstrates the prediction validity of the system.

该方法基于声波在水中传播的Snell定律，利用水中各线性分层间不同的声速梯度，绘制声线图，建立了几何自导作用距离的数学模型，并通过声线密度对几何作用距离进行预报，设计了声自导鱼雷几何作用距离预报系统，并通过系统软件实现了其功能，经测试，该系统在海上试验中取得了良好效果。

Unless we turn around in the next five minutes, we'll have to ditch into sea because we won't have enough fuel to get back to the airstrip.

除非我们在5分钟之内折返，我们得在海上迫降，因为我们没有足够的燃料飞回机场。

At the time of this story, they were all at sea.

在这个故事发生的时候，他的所有船只都在海上。

I say it is to wage war by land, sea and air.

我的回答是：在陆地上、在海上、在空中作战。

The way of an eagle in the sky, the way of a snake on a rock, the way of a ship on the high seas, and the way of a man with a girl.

19鹰在空中飞行；蛇在磐石上爬动；船在海上航行；男女相恋。

A few have managed to stay at sea for several months. In 2004 a sea glider built by the Scripps Institution of Oceanography in San Diego (and called Spray after Slocum's self-steering sailing ship) even managed to cross the strong currents in the Gulf Stream on a voyage to Bermuda.

很少有人能够成功在海上待上几个月。2004年由在圣地亚哥斯克里普斯海洋学研究所制造的海洋滑翔器（取名自斯洛克姆的自动转向帆船的&喷沫&）甚至在百慕大群岛的航行中成功的穿越了强大的墨西哥暖流。

A few 'institutional' nouns take no definite article when a certain role is implied: for example, at sea, in prison, and at/in college.

有几个'体制'名词采取没有明确的文章时，一定的作用是不言而喻的：例如，在海上，在监狱中，并在/大学。

A time of turkeys, stuffing, and pumpkin pie. A time for Indian corn, holiday parades and giant balloons

他们在海上顛簸了兩个月之后，终于在酷寒的十一月里，在现在的马莎塞州的普里茅斯登陸。

At sea their infiltrations to Guadalcanal were nearly all by night, and the fact that Japan has been beaten in most of the great night battles is probably due to superior U.S.

在海上他们对瓜达康纳尔岛的渗透几乎都在晚上，而但凡日本在大型夜战的失败都是因为美军有更强的侦查装备和火力。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
