In Chap. 1, the point was made that the greatest pressure in the oceans, about 110 MPa, is not particularly challenging in engineering terms. It is at the high end of the pressure range used in much hydraulic equipment and industrial machinery. The humble hydraulic car jack and road digger...
An obvious difference is that the field is noisy over major topographic features because it is based on extrapolating the pressure to sea level. Another difference is the meridional height gradient (created by the meridional temperature gradient through a depth of the atmosphere), which is not so...
Thepercentage of primary production grazed by the female C. euxinus wascalculated as 14.5% in April and 9.5% in September. 展开 关键词: grazing pressure vertical migration copepod Calanus Black Sea DOI: 10.1023/A:1003142209456 被引量: 40 ...
Compressed air may be utilized with pressure control and air relieving capabilities to the contained air pocket or pockets for the purpose of varying the sea-pressured air pressure and subsequently the surface vessel's draft depth. The design or design improvement enhances a surface vessels ...
Caves also record ancient life and past climates.The Mariana Trench, the Pacific Ocean The Mariana Trench, with the maximum depth of 11,034 meters, is the deepest part of Earth’s surface. Pressure there is intolerable, but creatures like sea cucumbers (海参) still exist. Scientists ...
The atmospheric pressure is 100 kPa and the total pressure on the top surface of the submarine is 900 kPa Calculate the depth of the top surface of the submarine below the surface of the sea. depth=___[3] 相关知识点: 试题来源: 解析...
Although overpressure distribution in the pre-Cretaceous section is broadly related to depth, large-scale compartmentalization of the main Jurassic/Triassic reservoirs has resulted in the generation of a number of distinct pressure cells. These pressure cells are bounded by major structural faults (e.g...
At a depth of 1000 m in an ocean (a) What is the absolute pressure? (b) What is the gauge pressure? (c) Find the force acting on the window of area 20 cm×20 cm of a submarine at this depth, the interior of which is maintained at sea level atmospheric pressure. (The density ...
