It is not the life buoy on board ship that saves the man when he is drowning nor is it his belief that it is an excellent and successful invention .
在一个人溺水的时候,不是在船上的救生圈就能救他;也不是相信这是一个优秀和成功的发明,就能够救他。
Data from a tsunami wave passing overhead are sent to a buoy on the sea surface , which zaps the information via satellite to monitoring stations in hawaii and elsewhere .
海啸波通过监测区时的数据被发送至海平面上的浮标,浮标通过卫星将信息传达给夏威夷和其他地方的监测站。
Depending on wave height and speed , as well as wavelength and water density , each buoy can produce up to 40 kilowatts of electricity .
The buoy examines patterns in shore-based radar to determine the ship 's location and points its camera in that direction .
浮标检查模式,通过岸基雷达来确定船舶的位置,并伸出它的摄像头。
The tsunami first reached a monitoring buoy just minutes after the quake occurred , and soon thereafter scientists released a forecast of wave heights and arrival times .
地震仅发生几分钟后海啸就突破了检测浮标,之后科学家很快发布了海啸高度和到达时间的预测。
Voltage is induced when waves cause coils located inside the buoy to move relative to the magnetic field of the anchored shaft . This process generates electricity .
波浪运动导致浮标内部的线圈与锚定的磁性中轴作相对运动,从而产生电能。
Following installation at the test site , a number of operations and tests will follow , examining the response of the buoy 's structure and mooring system to waves , and the power produced by the onboard generator .
Earlier in the day air force pilots saw white metallic objects , an aeroplane seat , an orange buoy and jet fuel stains in the water roughly 400 miles north of the archipelago in two areas around 35 miles apart , but there were no signs of life .
Petty officer 2nd class manuel izquierdo and petty officer 1st class brandon kelly look on after dropping a self locating data marker buoy , near the japanese fishing vessel ryou-un maru , in the gulf of alaska in this u.s. coast guard handout photo , april 4 , 2012 .
