在水下的

In this paper, a space model of antisubmarine homing torpedo's trajectory has been established based on the surface warship attacking underwater target, a formula which can be used to calculate the trajectory length of antisubmarine horning torpedo is also given.

在建立了水面舰艇发射反潜自导鱼雷攻击水下目标的空间弹道模型的基础上，提出了反潜自导鱼雷全弹道长度的一种计算公式。

Underwater security is a challenging job for the long-lasting antiterrorism task.

反恐将在相当长的时间内成为一个难以回避的主题，近岸水下反恐则是一项具有挑战意义的工作。

In the future, a few archaeologists may be able to use expensive equipment, such as the special diving suit and robot below, to investigate underwater remains in places too cold or deep for rubber suit and aqualungs.

以后，一些考古学家可能会用上像以下图示中的特殊潜水服和机器人等昂贵设备，去探索那些太冷或过深的地方的水下历史遗迹，在这些地方橡胶潜水服和氧气瓶派不上用场。

In the fluvial deposit environment, the quartz superficial characteristic is primarily by the inferior circle, the conchoidal breakage fracture and the submarine hit pit, revealing the transformation of current to the quartz; In lake-deposit environment, quartz sand superficial characteristic is by primarily abraded edges and parallel cleavage, the quartz maintained the primitive characteristic, indicating the quartz received few transformation of fluent, different quartz grain has their different curve character.

在河流沉积环境，石英砂的表面特征以次圆、贝壳状断口和水下撞击坑为主，显示了水流对石英砂颗粒表面的改造；在湖泊沉积环境中，石英砂的表面特征以多棱角和平行解理面为主，石英砂颗粒保持了原始的特征，表明了石英砂颗粒受到水流的改造比较少。不同沉积环境中石英砂颗粒表面结构特征都具有自己的曲线特征。

In the design of the structure, a new 2-D scanning machine is put forward which has overcome the limit of common underwater TV system influenced by the environment of water. It can scan 360 degrees in horizontal plane and 90 degrees in vertical plane, and there isn't dead angle.

根据以上内容的研究和分析，在结构设计方面，提出了二维扫描机构，它克服了一般水下电视系统由于使用特殊环境的限制不能进行扫描的缺点，可以进行水平360度，垂直90度全方位扫描，并且不存在盲区。

According to the manual, this binocular is immersible in 1.5m deep water for one hour and operational from -43 to+55 degs.

按照说明书的说法，该镜可以浸没于1.5m深的水下一小时，并且可以在-43 ~+55℃的温度条件下使用。

At the same time, new information about the underwater target can be got and the detectability can be increased.

在机载激光探测水下目标过程中，若采用偏振激光代替激光脉冲进行探测，不但可以压缩回波信号的动态范围，减少水面回波的影响，而且还能增加新的信息和可探测性。

In the future, a few archaeologists may be able to use expensiveequipment, such as the special diving suit and robot below, to

以后，一些考古学家可能会用上像以下图示中的特殊潜水服和机器人等昂贵设备，去探索那些太冷或过深的地方的水下历史遗迹，在这些地方橡胶潜水服和氧气瓶派不上用场。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
