海平面: 1.sea level 2.sea-level 3.datum level 4.base level mean sea level 平均海平面 sea level change 海平面变动 It"s probable the sea surface will rise. 海平面可能会升高. This land is on low sea level. 这块陆地在海平面下面. atmospheric pressure at sea level is 1013 millibars. 海平面的气压是毫巴. Equality of elevation above sea level. 等海拔高度海平面以上的高度相等 Fully one-fourth of Holland is below sealevel. 荷兰的整整四分之一在海平面下. (heraldry) rising from the sea. （纹章学）从海平面上升的. Holland is a country which horizon is under the sea. 荷兰是一个地平线低于海平面的国家. having a small elevation above the ground or horizon or sea level. 地面、地平线或者海平面以上较小的高度.

elevation是海拔，就是你理解的“陆地到海平面的高度”，地理上有个专有名词altitude高度也是这个意思。sea level是指海平面。和海拔的关系是：sea level is used as a standard in reckoning land elevation or sea depth.作为一个基准，既可以表示陆地高度，也可以表示海的深度。

1、sea level 指海平面 sea levels coastal area是指与海平面处于同一海拔的沿海地区 coastal areas 泛指沿海地区2、low carbon living 指低碳生活 low carbon life 也是低碳生活（之生活方式） 两者无本质区别3、studies["stu028cdiz]n. 研究；学习；学业（study的复数） 希望对你有所帮助

why is the sea level rising every year为什么海平面每年都在上升

按道理sea level应该只有一个, 不能使用复数沿海地区可以有多个，可以使用复数碳排放当作一种概念时，不可数，不能使用复数。但是当作动作讲的时候，可以有多次、多个碳排放动作，可以用复数。

海平面是海的平均高度也称大地水准面。指在某一时刻假设没有潮汐、波浪、海涌或其他扰动因素引起的海面波动，海洋所能保持的水平面。由于地球内部质量的不均一，地球表面各点的重力线方向并非都指向球心一点。这样就使处处和重力线方向相垂直的大地水准面，形成一个不规则的曲面。因而世界各国有各自确立的平均海平面，即大地水准面。我国是将青岛验潮站多年观测的黄海平均海平面，确定为我国使用的大地水准面，依此作为我国的高程起算零点。根据该高程起算面建立起来的高程系统，称为1956年黄海高程系。我国各地面点的海拔，均指由黄海平均海平面起算的高度。 参考资料http://baike.baidu.com/view/202808.htmhttp://baike.baidu.com/view/36833.htm

因为rise不是元音开头的，所以用a因为rise不是元音开头的，所以用a。1.Thewholeplaceisatsealevel整个地区与海平面齐平。2.Themeltingicecausedariseinsealevel.冰川消融造成海平面上升。3.We"reprobablyatanelevationofabout13,000feetabovesealevel.我们可能在大约海拔13,000英尺的高度。

黄海。全国各地的高程都以此为基准进行测算。任何一地点相对于黄海的平均海平面的高差，就称它为绝对标高。平均海面是指某地一定时期内每小时海面高度的算术平均值，又称平均海水面。它是大地测量和海道测量中的高程起算面，又称零面或基准面。mean sea level 指某地一定时期内每小时海面高度的算术平均值， 又称平均海水面。它是大地测量和海道测量中的高程算面，又称零面或 基准面。1956年以前，中国的 高程系有 大沽零点、青岛零点、废 黄河口零点、 吴淞零点、门零点、 罗星塔零点、珠江 基面等。1956年以后，统规定以青岛 验潮站的1950年至1956年 潮汐观测资料算的平均海面作为 高程基准面，并命名为 黄海平均海面。

above是“在...上方”的意思,是个介词,above the sea level是介词短语做表语,表明了主语的位置

c aboveabove the sea level高于海平面over我的理解是高于所有的，如果说高于平均海拔，over mean sea level 就可，above可以笼统的说高过。higher 后面不能加名词sea level

答案是C，一般表示在位置上高于某人某物时用above，这句话的意思是这座山高于海平面1000英尺，所以用above。希望我的答案对你有帮助~~

翻译为“海拔2000米”。

The Lake of Heaven Changbaishan is in Jilin Province, Northeast China. Much of this beautiful, mountainous area is thick forest. Changbaishan is China"s largest nature reserve and it is kept in its natural state for the people of China and visitors from all over the world to enjoy. The land varies in height from 700 meters above sea level to over 2,000 meters and is home to a great diversity of rare plants and animals . Among the rare animals are cranes, black bears , leopards and tigers. Many people come to Changbaishan to study its unique plants and animals. Others come to walk in the mountains, to see the spectacular waterfalls or to bathe in the hot water pools. However, the attraction that arouses the greatest appreciation in the reserve is Tianchi or the Lake of Heaven. Tianchi is a deep lake that has formed in the crater of a dead volcano on top of the mountain. The lake is 2,194 meters above sea level, and more than 200 meters deep. In winter the surface freezes over. It takes about an hour to climb from the end of the road to the top of the mountain. When you arrive you are rewarded not only with the sight of its clear waters, but also by the view of the other sixteen mountain peaks that surround Tianchi. There are many stories told about Tianchi. The most well-known concerns three young women from heaven. They were bathing in Tianchi when a bird flew above them and dropped a small fruit onto the dress of the youngest girl. When she picked up the fruit to smell it, it flew into her mouth. Having swallowed the fruit, the girl became pregnant and later gave birth to a handsome boy. It is said that this boy, who had a great gift for languages and persuasion, is the father of the Manchu people. If you are lucky enough to visit the Lake of Heaven with your loved one, don"t forget to drop a coin into the clear blue water to guarantee your love will be as deep and lasting as the lake itself. 天 池 长白山在中国东北的吉林省，这个美丽的山区大部分是茂密的森林。长白山是中国最大的自然保护区，保持着它的原始状态，以供中国人民和世界各地的游客们欣赏。这里地面的高度从海拔700米到2000多米不等，是多种多样稀有动植物的生长地。珍稀动物有白鹤、黑熊、豹子和老虎。许多人到长白山来研究珍奇的动植物。另外一些人则是到山里来走一走，看看那些蔚为壮观的瀑布，或者在温水池里泡个澡。然而保护区里最令人欣赏的地方则是天池，或者说是天上的湖。 天池是一个深水湖，是由山顶一个死火山的火山口形成的。湖的海拔高度为2,194米，水的深度超过200米，到冬天湖面就全部结冰了。从路的尽头到山顶约需一个小时。你一到达山顶就会得到回报—你不仅可以看见天池那清澈如镜的湖水，而且还可以看到天池四周的16座山峰。 天池有着许多传说故事，其中最著名的是关于从天上下凡的三位少女的故事。她们在天池洗澡时，突然有一只鸟飞到她们的上方，把一个小小的水果扔在最年轻的那个姑娘的衣服上。当她拿起来闻的时候，水果飞进了她的嘴里。姑娘吞食了这个果子，后来就怀孕了。过了一段时间，她生下了一个漂亮的小男孩。据说这个男孩就是满族人的祖先，具有语言天赋和很强的说服力。 如果你有幸与你所爱的人去游天池，别忘了投一枚硬币到清澈碧蓝的湖水中，以确保你们的爱情像湖水一样深厚、持久。

地球上的水，是在不停地运动着的。它无处不在，通过蒸发、冷凝、降水等连续不断地循环。水的循环过程具体可以分为以下三个步骤： 第一步是蒸发和蒸腾的水分子进入大气。 吸收太阳辐射热后，水分子从海洋、河流、湖泊、潮湿土壤和其他潮湿表面蒸发到大气中去；生长在地表的植物，通过茎叶的蒸发将水扩散到大气中，植物的这种蒸发作用通常又称为蒸腾。据估计，在一个生长季中0.4公顷的谷物几乎就可以蒸腾200万升的水，等于同等面积内43厘米深的水层。通过蒸发和蒸腾的水，水质都得到了纯化，是清洁水。 第二步是以降水形式返回大地。 水分子进入大气后，变为水汽随气流运动，在适当条件下，遇冷凝结形成降水，以雨或雪的形式降落到地面。降水不但给地球带来淡水，养育了千千万万的生命，同时，还能净化空气，把一些天然的和人为的污物从大气中洗去。 降水是陆地水资源的根本来源。我国多年来平均年降水量为632毫米，而全球陆地平均年降水量是834毫米。 第三步是重新返回蒸发点。 当降水到达地面时，一部分渗入地下，补给地下水；一部分从地表流掉，补给河流。地表的流水，即径流可以带走泥粒，导致侵蚀；也可以带走细菌、灰尘和化肥、农药等，因而径流常常是被污染的。最后千流归大海，水又回到海洋以及河流、湖泊等蒸发点。这就是地球上的水循环。 推动这种循环的永恒动力是太阳辐射。进入到地球上的太阳能约有23％消耗于海洋表面和陆地表面的蒸发上，当水汽凝结时，这些能量又重新释放出来。就全年平均情况来看，大约从北纬40度到南纬30度是一个广大的辐射过剩区域，而极地周围的高纬度地区是辐射亏损区。海陆之间，在不同的季节有着不同的亏损和盈余。只有把热量从盈余的地区向亏损的地区输送，才能达到全球的能量平衡。而水分循环是这种能量输送的主要途径之一。水在海洋中能够形成洋流，水又能够以气液相变的形式来大量地储存和输送能量。这种能量输送保持了全球的能量平衡，使得辐射的亏损区不至于太冷，辐射过剩区不至于太热，为生物提供了一种适宜的生活环境。 有时水循环会出现一些较特殊的情况。在高纬度和高海拔区，自大气层降下的不是水而是雪。落在极地区或山地的雪积久可成冰，水因此得到保存，算是退出循环，退出时间一般为几十年、几百年或几千年。因此，冰雪的固结与消融，影响着参与水循环的水的总量，进而影响全球海面变化。 南极冰盖和格陵兰冰盖是世界上最大的冰库。如果全部融化，海洋的水位就会上升大约60米，这意味着各大洲的沿海地区、包括许多世界级大城市都将被淹没，海平面将达到纽约曼哈顿摩天大楼的20层楼那么高。 水分循环的过程是非常复杂的。除了这种海陆之间的水分循环外，海洋有自己的洋流等水圈内部的水循环；大气圈里有随着大气环流进行的大气内部水循环；大气圈与陆地之间，大气圈与洋面之间，有着水汽形成降水，降落的水分又被蒸发的直接循环；岩石圈上存在着地表水与地下水之间的转换与循环；生物体内也有着生物水的循环等。 水分循环把地球上所有的水，无论是大气、海洋、地表还是生物圈中的水，都纳入了一个综合的自然系统中，水圈内所有的水都参与水的循环。像人体中，从饮水到水排出体外只要几个小时；大气中的水，从蒸发进入大气，到形成降水离开大气，平均来说，完成一次循环要8～10天；世界大洋中的水，如果都要蒸发进入大气，完成一次水分循环的过程，需要3000～4000年。 水分循环系统是一个水的自然净化系统。水不断地从潮湿的表面蒸发，或者从植物表面蒸腾，当水蒸气进入大气时，大部分杂质留下来。雨水到了地面经过沙石的过滤和沉淀，成为洁净的水。在这个净化过程中，海洋起着巨大的作用。太阳、海洋和大气像一个巨大的蒸馏装置，时刻不停地运转着。 由于水分循环的存在，使得水成为地球上最活跃的物质，使全球的水量和热量得到均衡调节。正是由于这种年复一年、日复一日永不停息的水分循环，才使得大气圈气象万千，使得地球表面千姿百态，生机盎然。假如水分循环停止，将再也看不到电闪雷鸣、雨雪霜雹；再也没有晴、雨、阴、云的天气变化；再也看不到江、河、湖、沼；当然更不会有森林、草原；动物与人类也将不存在。------------------------------------------------On Earth"s water, is in does not stop the movement. Its there is noplace in, through does not evaporate, the condensation, theprecipitation and so on continuously unceasingly circulates. The watercyclic process specifically may divide into following three steps: First step is evaporates with the transpiration hydrone enters theatmosphere. After absorbs the solar radiating heat, hydrone from sea, rivers,lake, moist soil and other moist surface evaporation to atmosphere in;The growth in the surface plant, proliferates through stem leaf"sevaporating the water to the atmosphere in, plant"s this kind ofevaporation usually is called the transpiration. It is estimated, in agrowth season 0.4 hectares grain nearly may the transpiration 200myrialiters water, be equal to in the same level area 43 centimeterdeep water level. Through evaporated with the transpiration water, thewater quality all obtained the purification, was the clean water. Second step is returns to the earth by the precipitation form. After the hydrone enters the atmosphere, becomes the water vapor alongwith the air current movement, under the suitable condition, meets thecondensation knot to form the precipitation, descends the ground bythe rain or the snow form. The precipitation not only brings the freshwater to the Earth, has raised the great amount life, simultaneously,but also can purify the air, washes off some natural and theartificial contamination from the atmosphere. The precipitation is the land water resources radical origin. Ourcountry for many years the average year precipitation has been 632millimeters, but the global land average year precipitation is 834millimeters. Third step is rereturns 蒸发点. When the precipitation arrives the ground, part of permeatingunderground, military supplies ground water; A part falls from theplace sheet current, military supplies rivers. The surface runningwater, namely the runoff may carry off the putty grain, causes thecorrosion; Also may carry off the bacterium, the dust and the chemicalfertilizer, the agricultural chemicals and so on, thus the runofffrequently is polluted. Finally thousand class turn over to the sea,the water to return to the sea as well as the rivers, the lake and soon 蒸发点. This is on Earth"s water cycle. Impels this kind of circulation the eternal power is the solarradiation. Enters the solar energy approximately has 23% consumptionto the Earth on to the sea surface and on land surface evaporating,when the water vapor congeals, these energies rerelease. Looked on thewhole year average situation that, probably from north latitude 40 tosouth latitudes 30 is general radiations too much regions, but aroundthe polar high latitude area radiates the loss area. Between the sealand, has the different loss and the earnings in the different season.Only has the quantity of heat from the earnings area to the loss localtransportation, can achieve global the energy balance. But thehydrologic cycle is one of this kind of energy transport main ways.The water can form the ocean current in the sea, the water can be madthe liquid phase changes the form comes massively the storage and thetransportation energy. This kind of energy transport maintained theglobal energy balance, causes the radiation the loss area not as fortoo coldly, the radiation area as for too is not too much hot, hasprovided the living conditions for the biology which one kind issuitable. Sometimes the water cycle can have some more special situation. In thehigh latitude and the high elevation area, the arrogant aerospherelowers is not Shui Er is a snow. Falls accumulates in extremely localor the mountainous region snow may become the ice, the water thereforeobtains the preservation, is withdraws from the circulation, thewithdrawal time generally is several dozens year, several hundred yearor several millenniums. Therefore, snow and ice solidifying withmelts, is affecting the participation water cycle water totalquantity, then affects the global sea level change. The south pole ice cap and the Greenland ice cap are in the world thebiggest ice bunker. If completely melts, the sea water level can risethe about 60 meters, this meant each big continent the coastal area,is all submerged including many world-classs big city, the sea levelachieved the New York Manhattan skyscraper 20 buildings are that high. The hydrologic cycle process is extremely complex. Besides this kindof sea land between hydrologic cycle, the sea has ocean currenthydrosphere interior the and so on own water cycle; In the aerospherehas the atmospheric internal water circulation which carries on alongwith the atmospheric circulation; Between the aerosphere and the land,the aerosphere with 洋面 between, has the water vapor to form theprecipitation, descends the moisture content the direct circulationwhich evaporates; On the lithosphere has between the surface water andthe ground water transformation and the circulation; Biological invivo also has the biological water the circulation and so on. Hydrologic cycle Earth on all water, regardless of is the atmosphere,the sea, the surface or in the biosphere water, all has bought intoline with in a comprehensive natural system, in the hydrosphere allwater all participate in the water the circulation. In the picturehuman body, discharges in vitro from the potable water to the water solong as several hours; In the atmospheric water, from evaporatesenters the atmosphere, to forms the precipitation to leave theatmosphere, on average, completes a time of circulation to want 8 ~ 10days; In world ocean water, if all must evaporate enters theatmosphere, completes a time of hydrologic cycle the process, needs3000 ~ in 4000. The hydrologic cycle system is a water nature purification system.Water unceasingly from moist surface evaporation, or from plantsurface transpiration, when the steam enters the atmosphere, themajority of impurities stay behind. The rain water arrived the groundafter grit filtering with the precipitation, becomes the pure water.In this purification process, the sea is playing the huge role. Thesun, the sea and the atmosphere like a huge distilling apparatus, thetime does not stop is revolving. As a result of the hydrologic cycle existence, causes Shuicheng forthe Earth on the most active matter, causes global the water volumeand the quantity of heat is under the proportional-plus-floatingcontrol. Is precisely because this kind never ceases year after year,day after day the hydrologic cycle, only then causes the aerosphere tobe spectacular, causes the earth"s surface differ in thousands ofways, vitality abundant. If the hydrologic cycle stops, again also theblind lightning flash will be thunderous, the sleet frost hail; Againalso does not have clearly, the rain, to be cloudy, the cloud weatherchange; Again also the blind river, the river, the lake, moor;Certainly cannot have the forest, the prairie; The animal and thehumanity also will not exist. ----------------------------------------------------其实也就是 蒸发>降雨>地表径流>流入大海>蒸发Evaporates > Rains > Surface runoff > Inflow sea >Evaporates

最后一句beautiful应该改成beauty吧

海拔是指地面某个地点高出海平面的垂直距离。网络上，海拔一词也经常被用为一个人身高的代指。海拔就是超出海水面的高度。但海面潮起潮落，大浪小浪不停，可以说没有一刻风平浪静的时候，而且每月每日涨潮与落潮的海面高度也是有明显差别的。因此，人们就想到只能用一个确定的平均海水面来作为海拔的起算面。海拔也就定义为高出平均海水面的高度。这就是通常人们所说的高程或绝对高程。（Above sea level） 由平均海平面起算的地面点高程，称为海拔高度或绝对高程。平均海平面， 大地水准面也称大地水准面。由于地球内部质量的不均一，地球表面各点的重力线方向并非都指向球心一点。这样就使处处和重力线方向相垂直的大地水准面，形成一个不规则的曲面。因而世界各国有各自确立的平均海平面，即大地水准面

“我们的工厂和家庭（可引申为“生产和生活”）燃烧煤炭和石油。每年都会有一些地方发生森林火灾。许多科学家认为气候正在变暖。南北极的地球温度大概上升了7摄氏度。冰雪将会融化。海平面将上升约7米。由此造成的结果是：伦敦、东京和纽约这样的城市都将被水淹没；许多沿海的港口、城镇都将消失在水下。还有一些科学家认为，煤炭、木材和油燃烧时产生的粉尘、烟雾和其他污染物将遮挡住阳光。之后地球温度将会降低，欧洲和北美洲将会被冰川覆盖。当空气中的化学物质同雨水混合，即产生酸雨。酸雨会毁坏森林，杀死湖泊和江河中的生物，造成极大地伤害。（此处为中文通顺，稍微调整了一下前后文句子顺序。）人们开始意识到问题的严重性。他们发现顺应自然比征服自然更重要。人们正在努力用各种方式拯救地球。但是最重要的工作之一是让人们明白：拯救地球就是拯救人类自己。”LZ，我猜想你文中的earth应该是首字母大写的Earth。Earth是专有名字，也就是“地球”的意思，但earth是“土壤”的意思。你看一下，如果原文是Earth，那么我这边的翻译就没问题。如果是earth，就需要把文中的“地球”替换成“土壤”。就是这些，希望能帮到你。

Christina is on a two-week vacation. This is the first vacation she has had for a long time. The last vacation she took was more than two years ago. Now she is visiting a friend in San Francisco.

要

900米。海平面的相关定义有“全球海平面”、“本地海平面”以及“相对海平面趋势”等。由于多种因素影响，海平面不是完全平的，海洋表面有三个较大的隆起区域，一个在澳大利亚东北部海区，隆起高达76米，还有三个较大的凹陷区域，一个在印度洋上，凹陷深达112米。 海平面（Sealevel）是海的平均高度。指在某一时刻假设没有潮汐、波浪、海涌或其他扰动因素引起的海面波动，海洋所能保持的水平面。

是 above the sea level ， sea 做level的定语，就是特指了，需要有定冠词。如果非要用 above sea level 也不算错，尤其在口语表达上面。

The sea level rises海平面上升.As the sea level rises, more islands will disappear. 随着海平面上升，将会有更多岛屿因而消失不明白可以追问我，满意的话请点击【采纳】

应该用above

above sea level 因为此时的sea 为统称,above the sea level 也没有错.最佳答案好像应该是后者

选【B】 在海平面之上用的是above the sea level,是固定用法

above 用于表示地平线，海拔之类的表示希望能采纳，谢谢了

你好， sealed eyeliner 意思是： 密封的眼线笔请采纳seal 动词, 密封, sealed 密封的eyeline 眼线. eyeliner 眼线笔

顾名思义，所谓海拔就是超出海水面的高度。但海面潮起潮落，大浪小浪不停，可以说没有一刻风平浪静的时候，而且每月每日涨潮与落潮的海面高度也是有明显差别的。因此，人们就想到只能用一个确定的平均海水面来作为海拔的起算面。海拔也就定义为高出平均海水面的高度。这就是通常人们所说的高程或绝对高程。（Above sea level） 由平均海平面起算的地面点高程，称为海拔高度或绝对高程。平均海平面，也称大地水准面。由于地球内部质量的不均一，地球表面各点的重力线方向并非都指向球心一点。这样就使处处和重力线方向相垂直的大地水准面，形成一个不规则的曲面。因而世界各国有各自确立的平均海平面，即大地水准面。我国1987年规定将青岛验潮站1952年1月1日~1979年12月31日所测定的黄海平均海水面作为全国高程的起算面。并推测得青岛观象山上国家水准原点高程为72.260m。根据该高程起算面建立起来的高程系统，称为1985国家高程基准。我国各地面点的海拔，均指由黄海平均海平面起算的高度。如何得出一个确定的平均海水面呢？对此，测绘专家们很早就想到通过在沿海设置验潮站的办法。选择对一个国家或地区来说具有位置适中、外海海面开阔、海底平坦、地质结构稳定、有代表性和规律性的半日潮等特点的港区建立一个长期使用的验潮站，根据长期验潮资料来确定一个平均海水面，把它作为零高程面。然后用精密水准测量联测到陆地上预先设置好的水准原点，测定出这个点的海拔高度作为一个国家或整个地区的起算高程。网络时代的今天,海拔一词也经常被用为一个人身高的代指.

就是海面呀一般我们从海平面来记录高度.你在家里放一盆水伸一个尺子进去,水上的高度,我们叫水面上多高,水下的深度,我们叫水面下多少.地理上的高度,就是用海平面做为零开始测量的,说珠峰有8848.8,那就是相对于海平面的.这个记量的方面,可以用气温计还想象.7度,与零下5度.0度本身就相当于海平面.

According to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills (see picture) to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere. 据美国政府公布，太平洋海岸外的离岸风电场每年可产生900吉瓦的电力。不过海水太深，即使是最高的风电机（见图）也到不了海底。挪威的离岸正进行一项实验，可以将离岸风电机装在任何地方。 The project, called Hywind, is the world"s first large-scale deepwater wind turbine. Although it uses a fairly standard 152-ton, 2.3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture), a technology Hywind"s creator,the Norwegian company StatoilHydro,has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable; these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywind"s stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September. 该项目称为Hywind，是世界上第一个大型深水风力涡轮发电机。虽然它采用了比较标准的152吨，发电量为2.3兆瓦的涡轮机，Hywind代表着崭新的技术。涡轮机安装在一座浮动的平台上，塔体水面高度213英尺（见图），最近由挪威国家石油海德罗公司 (StatoilHydro）研发。其安装在内置石块的钢铁支架，深入海底达328英尺，并由三根钢缆固定在海床之上，将平台保持稳定，及以防涡轮机被波浪推动作上下摆动。Hywind风电机证明能在寒冷及恶劣的海洋环境中保持稳定性，甚至适用于水深极深的角落。假若一切能按计划进行，涡轮机最快可在9月初，在离挪威西南海岸6英里之处开始发电。 To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it"s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar"s to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades (see picture ). 为了大规模发电，商业风电场将不得不使用比Hywind更大的涡轮机，但要在海洋中央的浮石上平衡如此高的大型涡轮机是很困难的。为了使涡轮机更重，整个spar设计了一种新型的风力涡轮机，其变速箱位于海平面，而不是叶片后面（见图） 大规模风力发电，需要使用比Hywind更大型的商业化的风力涡轮机，但是，大型的涡轮机难以在漂浮于海洋中的平台上平衡。为了增加涡轮机的重量，整座平台的设计须配合新型的风力涡轮机，变速箱会安装在水的平面上，而非叶片的背后（见图）。 Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet"s surface to one of the best low-carbon power sources available. Hywind只是一次试运行，但完善浮式风电场技术的好处可能非常大。在海上，风力通常比靠近海岸的地方更大、更稳定，因为所有现有的海上风车都是在海岸附近种植的。从陆地上看不到深海农场，这有助于克服风车的视觉障碍。如果这项技术流行起来，它将为地球表面的广大地区提供最好的低碳能源之一。 Hywind目前仍处于试验阶段，但完善漂浮式风电技术将带来极大效益。在海中心的风力一般都比靠近岸边强而稳定，现有的离岸风电机都装在近岸。在近岸看不见深海风电场，这有助于减少因美观而反对设置离岸风电机的声音。假若这项技术得到普及，它能以广大的地球表面提供予拓展最上成的低碳能源之用。
