风能
(wind energy)
地球表面大量空气流动所产生的动能。由于地面各处受太阳辐照后气温变化不同和空气中水蒸气的含量不同,因而引起各地气压的差异,在水平方向高压空气向低压地区流动,即形成风。风能资源决定于风能密度和可利用的风能年累积小时数。风能密度是单位迎风面积可获得的风的功率,与风速的三次方和空气密度成正比关系。据估算,全世界的风能总量约1300亿千瓦,中国的风能总量约16亿千瓦。风能资源受地形的影响较大,世界风能资源多集中在沿海和开阔大陆的收缩地带,如美国的加利福尼亚州沿岸和北欧一些国家,中国的东南沿海、内蒙古、新疆和甘肃一带风能资源也很丰富。中国东南沿海及附近岛屿的风能密度可达300瓦/米2(W/m2)以上,3~20米/秒风速年累计超过6000小时 。内陆风能资源最好的区域 ,沿内蒙古至 新疆一带,风能密度也在200~300W/m2,3 ~20米/秒风速年累计5000~6000小时。这些地区适于发展风力发电和风力提水。新疆达坂城风力发电站1992年已装机5500千瓦,是中国最大的风力电站
在自然界中,风是一种可再生、无污染而且储量巨大的能源。随着全球气候变暖和能源危机,各国都在加紧对风力的开发和利用,尽量减少二氧化碳等温室气体的排放,保护我们赖以生存的地球。
风能的利用主要是以风能作动力和风力发电两种形式,其中又以风力发电为主,
以风能作动力,就是利用风来直接带动各种机械装置,如带动水泵提水等这种风力发动机的优点是:投资少、工效高、经济耐用。目前,世界上约有一白多万台风力提水机在运转。澳大利亚的许多牧场,都设有这种风力提水机。在很多风力资源丰富的国家,科学家们还利用风力发动机铡草、磨面和加工饲料等。
利用风力发电,以丹麦应用最早,而且使用较普遍。丹麦虽只有500多万人口,却是世界风能发电大国和发电风轮生产大国,世界10大风轮生产厂家有5家在丹麦,世界60%以上的风轮制造厂都在使用丹麦的技术,是名副其实的“风车大国”。
wind energy
Kinetic energy proced by earth surface large amount of air flow. The steam contents are different in diversity and air since the floor accepts sun irradiation queen air temperature change everywhere, difference arousing everywhere pressure as a result, area flows to low pressure , is to form wind in high-handed air of level direction. Wind energy source resource decides the Yu Feng Neng density sum but the wind energy source year making use of accumulates hour number. Wind energy source density is that the unit faces the wind covering an area of the groundless power gaining , the cube and air density direct proportion with wind speed concern. Evidence is estimated, the whole world wind energy source all quantity about 130 billion kilowatt , Chinese wind energy source all quantity about 1,600,000,000 kilowatt. Wind energy source resource accepts the landform effect more, world wind energy source resource is many contraction zone focusing on littoral and open continent, Inner Mongolia , Xinjiang and Gansu Province area wind energy source resource enrich Chinese southeast along the coast, also very much if American California composes in reply along the bank a few Northern Europe countries. Littoral and neighbouring Chinese southeast island and islet wind energy source density may amount to 300 watts of/ rice 3 ~ 20 meters of/ second of wind speed year accumulative totals exceed 6000 hours above 2 (W/m2). Best inner Lu Feng Neng resource area, one takes along Inner Mongolia to Xinjiang, wind energy source density also is in 6000 hours of 200 ~ 300 W/m2 , 3 ~ 20 meters of/ second of wind speed year accumulated 5000 ~. These area is suitable for developing wind power generating electricity preparing wind power carrying water. That Xinjiang reaches the hill slope city wind power power station already packing machine in 1992 is a maximal Chinese wind power power station 5,500,000 watts.
The sources of energy the middle, wind in Nature to be that one kind of regenerate , the nothing contaminate and reserves are gigantic. With the fact that the global climate is changed into the warm energy crisis,stepping up to the wind power exploitation and making use of in every country , cut down a carbon dioxide to the full waiting for green-house gas emission , protect the earth on which we rely for existing. The wind energy source making use of is two kinds forms mainly assume driving force with the wind energy source preparing wind power generating electricity , generate electricity among them with wind power give first place to,
Assume driving force with the wind energy source , be to make use of wind to come to set various mechanism in motion directly, waiting for this wind power engine merit if drive a water pump to carry water is: Investment is few , work efficiency is tall , economy is rable. At present, make an appointment with in the world having one Baiowan stage manner to mention water machine strenuously in turn over. Many grazing land of Aussie, set up have this wind power to mention water machine. In many countries of wind power abound in natural resources, scientists making use of the wind power engine to chop fodder , grinding face and processing feed and so on.
The application making use of wind power to generate electricity, with Denmark is the earliest , usage is more common and. Be that world wind energy source electric power generation Great Power and electric power generation wind wheel proce Great Power but though Denmark only having more than 5,000,000 population,the manufacturer world 10 gales wheels are proced has 5 being in Denmark , the world 60% the above wind wheel manufactory technology all in using Danish, is "pinwheel Great Power " true to self's name.
② 有关风力发电或太阳能发电文章的英文
Fossil energy and nuclear energy are considered nonrenewable energy
types. Nonrenewable energy is obtained from sources at a rate that exceeds
the rate at which the sources are replenished. For example, if the biogenic
origin of fossil fuels is correct, we could consider fossil fuels renewable
over a period of millions of years, but the existing store of fossil fuels is
being consumed over a period of centuries. Because we are consuming
fossil fuels at a rate that exceeds the rate of replenishment, we consider
fossil fuels nonrenewable. Similar comments apply to nuclear fuels such
as uranium, as we observe in later chapters. Solar energy is considered
a renewable energy for the following reasons.1
Renewable energy is energy obtained from sources at a rate that is less
than or equal to the rate at which the source is replenished. In the case
of solar energy, we can use only the amount of energy provided by the
sun. Because the remaining lifetime of the sun is measured in millions
of years, many people consider solar energy an inexhaustible supply of
energy. In fact, solar energy from the sun is finite, but should be available
for use by many generations of people. Solar energy is therefore considered
renewable. Energy sources that are associated with solar energy, such as
wind and biomass, are also considered renewable.
Solar radiation may be converted to other forms of energy by several
conversion processes. Thermal conversion relies on the absorption of solar
energy to heat a cool surface. Biological conversion of solar energy relies
on photosynthesis. Photovoltaic conversion generates electrical power by
the generation of an electrical current as a result of a quantum mechanical
process. Wind power and ocean energy conversion rely on atmospheric
pressure gradients and oceanic temperature gradients to generate electrical
power. In this chapter we focus on thermal conversion.We first discuss the
source of available solar energy, and then consider solar energy technology
in two of its three forms: passive solar, and active solar. The third form of
solar energy, solar electric, is discussed in the next chapter. We end this
chapter with a discussion of solar power plants.
③ 风能发电的历史英语作文
风很早就被人们利用--主要是通过风车来抽水、磨面……。人们感兴趣的,首先是如何利用风来发电。风是一种潜力很大的新能源,人们也许还记得,十八世纪初,横扫英法两国的一次狂暴大风,吹毁了四百座风力磨坊、八百座房屋、一百座教堂、四百多条帆船,并有数千人受到伤害,二十五万株大树连根拔起。仅就拔树一事而论,风在数秒钟内就发出了一千万马力(即750万千瓦;一马力等于0.75千瓦)的功率!有人估计过,地球上可用来发电的风力资源约有100亿千瓦,几乎是全世界水力发电量的10倍。全世界每年燃烧煤所获得的能量,只有风力在一年内所提供能量的三分之一。因此,国内外都很重视利用风力来发电,开发新能源。
The wind was used by people for a long time-mainly through windmills to pump water and grind the surface... People are interested in how to use wind to generate electricity.
Wind is a new energy source with great potential. People may still remember that in the early eighteenth century, a violent wind swept across Britain and France destroyed 400 wind mills, 800 houses, 100 churches, and 4 More than a hundred sailing ships, thousands of people were injured, 250,000 big trees were uprooted. As far as pulling trees is concerned, the wind can emit 10 million horsepower (that is, 7.5 million kilowatts; one horsepower is equal to 0.75 kilowatts) in a few seconds! Someone has estimated that the amount of wind resources available for power generation on the earth is about There are 10 billion kilowatts, almost 10 times the world's hydroelectric power generation. The energy obtained by burning coal every year in the world is only one third of the energy provided by wind power in a year. Theref
