Messages can be sent across theocean by radio or by cable(电缆). The cable lies on the sea bottom and it has to have very good insulation. If any part of it is weak, the water will get through and stop all signals .The first cable under the sea was between England and France. It...
Touga is a country formed of about 169 islands in the South Pacific Ocean.Most of the country's 100,000 people live on the main island,called Tongatapu.Like most island nations,Tonga gets its Internet through a cable that runs deep under the sea. ...
a long-distance communications cable laid on the sea or ocean bottom, to depths of several thousand meters. The first sea cable for telegraphy was a one-conductor cable with gutta-percha insulation. It was laid in 1850 across the Strait of Dover between Dover and Calais. A transatlantic teleg...
According to the relative criterion requirement,thesubsea cableshould be buried under seabed1. 根据规范要求,油田平台间海底电缆需要埋设在泥面以下1。 4) ocean-bottom cable 海底电缆 1. Multiple suppression of the seismic data collected byocean-bottom cable; ...
A device is described which prevents, during deployment of an ocean cable system, torque build-up in a heavy armor cable section from being abruptly applied to a next-connected light armor cable section. A set of helically-wound steel armor rods rigidly attached to the heavier cable section fo...
Cable has strong nonlinear characteristics under the static or dynamic force, and if the frequency ratio of the boundary excitation meet some conditions, c... H Shentu,L Zhou 被引量: 0发表: 2015年 Influence of axial ligation on the spin state and exchange coupling in heterotrimetallic bis[iro...
In the present study, the penetration characteristics of anchor piles into the soil under which subsea HVDC cables are embedded were evaluated using numerical simulations and field verification tests. The numerical simulation for the soil penetration phenomena of anchor piles was carried out using the ...
This paper proposes a novel motion-tracking control methodology for an underwater cable-driven parallel mechanism (CDPM) that achieves calculation of dynamic tension constraint values, tension planning, parameter linearization, and motion tracking. The control objective is divided into three sub-objectives...
