海面下的

Finally, applications of the anomalous propagation of microwave in tropospheric ducts are discussed: in connection with concrete radar parameters, effects of ducts on radar range and detection performance are discussed, the results obtained are of great value for the overall design of radar systems; by use of the interference standards of ITU-R, the co-ordination area of satellite earth-station under tropospheric ducts environment is studied ; by explaining the relationship between evaporation duct and advection fog, a new way to forecast sea advection fog from evaporation duct is provided.

最后讨论了对流层大气波导环境下电波异常传播特性的应用：结合具体的雷达系统参数，模拟计算了大气波导对雷达作用距离及发现概率的影响，对雷达系统的总体设计具有重要的参考价值；对表面大气波导环境下的卫星地球站通信协调区域进行了确定，从理论上很好地给出了协调距离量级的概念，为卫星地球站与地面微波站之间的协调提供了依据和参考；分析了利用海面蒸发波导来快速预测平流海雾的新方法，完善了平流海雾的预报方法，对海上安全作业和生产具有重要的意义。

That you're 12,500 feet beneath the sea.

你是在海面下12500英尺的地方

In condition of obtaining two parameters of antenna brightness temperature at sea-water area and the oil film area with single microwave radiometer (8mm) of fix antenna, the model of calculating the oil film thickness of s outh China sea with airborne remote sensing was developed. The measured results over sea were closed with calculated values of the model.

提出了在单波段(8mm)固定天线微波辐射计获取海水区与油膜区天线亮温两参数条件下的航空遥感南海海面油膜厚度计算模式，海上航空遥感测量实验与模式计算结果基本符合。

They surged to and fro like the waves of the Icarian Sea, when the east and south winds break from heaven's clouds to lash them; or as when the west wind sweeps over a field of corn and the ears bow beneath the blast, even so were they swayed as they flew with loud cries towards the ships, and the dust from under their feet rose heavenward.

会场喧嚣沸腾，就像从天父宙斯制驭的云层里冲扫而下的东风和南风，在伊卡里亚海面掀起了滔天巨浪。宛如阵阵强劲的西风，扫过一大片密沉沉的谷田，呼喊咆哮，刮垂下庄稼的穗耳集会土崩瓦解，人们乱作一团，朝着

Riptide is a strong underwater current.It moves quickly away from shore and out to sea .

激潮是海面下一种强大的暗流，从海岩岸迅速地流向大海。

It took a sounding by the CTD sensor to detect the thermocline lying just 60 feet under the surface. We had arrived.

用CTD传感器可以探测到海面下不过20米深处的温越层，我们到了。

Except for his thrashing, the air above was as calm as the water below, and just as dark.

除了他的冲击之外，海面上的空气也和海面下的水一样平静，一样黑暗。

Thus, for three tropical cyclones occurred on different regions, three sets of altimeter-derived data of the sea surface wind and wave are selected, their structural features and relations between the wind and the wave under the influence of the tropical cyclones are analyzed respectively, finally, the most frequent occurring relations between the sea surface wind and the wave of the tropical cyclone over the South China Sea and two hindcast methods for wind field of typhoon based on altimeter-derived wind speed are presented.

据此，选取了高度计获取的3个出现在不同海域的热带气旋影响下的海面风、浪资料，进一步分析各个气旋影响下的海面风、浪结构特征及其关系，并给出了南海海域气旋海况下最可能的海面风、浪关系以及基于高度计风速资料的两种台风风场后报方法。

Pacific ocean is almost as large as the other three ocean plus together. the deepest part reach to 10973 meters below the sea and this deapth even exceed the highth of the highest ximalaya moutain in the world

太平洋几乎和其他三个大洋加起来一样大，其最深部分达到海面下 10，973米，这个深度甚至超过了喜马拉雅上上世界最高峰的高度。

Studies of the Weddell seal in the laboratory have described the physiological mechanisms that allow the seal to cope with the extreme oxygen deprivation that occurs during its longest dives, which can extend 500 meters below the ocean's surface and last for over 70 minutes.

有关 W 海豹的实验室研究表明，其生理机制使其能适应最长潜水下的极端缺氧，在距离海面500米下持续70分钟。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.
