从网上给你找的，看合适不?不合适的话再给你找EnergyEnergy makes the world go， It is indispensible to both animal life and human We get heat energy from the food we eat， light energy from the sun and electricity from In the hot summer when there ia a power outage we feel all the more the need for electric energy which powers the electric fan md air-There are different sources of The rivers and streams are a good source for electrie The san provides us with light， heat and There is also sound energy in the radio transformed from electric The energy can be changed from one form to It can never be exhausted nor It just goes on changing in It is important for us to make use of Solar energy is being made to generate electricity， to cook and to Atomic energy is used in industry and aviation and many other We are now doing our best to inake energy serve our people in every way possible这是关于解决能源短缺的文章:Energy shortage is a very serious problem in the Many people worry that energy resources on the earth will be exhausted if we use them in an unchecked This， most people agree， will cause serious problems and even crisis and jeopardize the survival of mankind On the one hand， most people agree that the problem can be solved in one way or One is to conserve and save our Energy refers not only to coal， oil， or natural gases but also to goods， land and water， Most countries have realized the wastefulness in their using of They are trying to conserve For example， some countries have a daylight saving system to use less electricity for Some cities have enforced water savers at public such as restrooms and Some have enforced serious penalties on overuse of electricity， water， and farming By these means， people hope the drain on energy resources could be slowed However， conservation alone cannot solve the Another way， perhaps the best I think，， is to develop new energy Obviously， no matter how hard we try to save energy resources and how abundant they are， we will use them up sooner or I think there are many energy resources that we can develop and We don%26rsquo;t have to depend only on the current conventional energy There are many other energy resources that we can develop such as nuclear power， waterpower and solar These resources， if developed， can completely replace the conventional energy and thus solve the problem of energy 这是具体关于太阳能的并附翻译:In general vacuum tube collectors are used in solar process heat Another possibility is to use transparent insulated flatplate A critical point however， is that most of the common transparent insulating materials can not withstand hightemperatures because they consist of Thus， temperature resistive collector covers combining a high transmisivity with alow U-value are One possibility is to use capillaries made of glass instead of Measurement results of collector efficiency and incident angle modifier will be presented as well as calculated energy gains forthree different collectors: a vacuum tube collector (Giordano I， France)， a CPC vacuum tube collector (microthermEnergietechnik， Germany) and a new flat plate collector using glass capillary as transparent insulation (SET， Germany)一般来说，太阳能热利用系统中都是采用真空管集热器。另一种则是采用透明绝热的平板集热器。然而由于普通透明绝热材料是由塑胶材料构成，一个关键问题就是不耐高温。因此，需要一种既耐高温又具有低传热系数的透明集热盖板，而使用由玻璃制成的毛细管替代塑胶材料则成为可能。文章将提供集热器效率、附带的角度改变量以及3种不同类型集热器的得热量的测试数据。这3种集热器分别是某种真空管集热器；某种CPC真空管集热器；一种使用玻璃毛细管作为透明隔热材料的新型平板集热器。
题目：Geothermal resources 正文：Geothermal resources in the world's oldest energy It is estimated that the total thermal energy of the Earth's interior， about all the coal reserves of about 7 billion Year from Earth's interior heat loss through the surface， equivalent to 1，000 million barrels of oil burning On geothermal sources， there are several Is generally believed that the geothermal evolution of radioactive elements mainly come from the earth's interior heat release， followed by rotation of the Earth's rotation can be generated and gravitational differentiation， chemical reactions， heat release and other rock and mineral During the formation of the Earth， the total amount of these heat dissipation of heat over the Earth， an enormous heat reserves， so that partial melting of crustal igneous and metamorphic Basic calculation is now out， the planet's core temperature reaches 6000 ° C， temperature of the bottom crust 900-1000 ° C， the surface layer at room temperature (about 15 meters from the ground) about 15 kilometers of the following， the increase of temperature increased with The average temperature of geothermal is about 3 ° C/100 m Geothermal warming rates in different regions are different， close to the average warming rate is called the normal temperature range， higher than the average warming rate of the region， said geothermal Geothermal anomaly area is research and development of geothermal resources of the main Crustal plate edge， deep fault and the volcanic belt at the other， is obvious geothermal Exploration of geothermal resources survey， the general use of surface geothermal survey， drilling and various geophysical Infrared remote sensing technology in exploration in recent years achieved remarkable The late 20th century， the exploitation of geothermal resources were mainly shallow， heat storage， and have a fluid (water or artificial irrigation) lead to heat transfer to the surface of the wet geothermal Hot dry rock geothermal resources and low-temperature geothermal fields of wetland research development and utilization in the pilot China， rich in geothermal resources， has a long mining history， past the main advantage of hot spring bath After 1970， in Guangdong Fengshun， Huailai， Tianjin， and Tibet to have been carried out in thermal power generation， building heating， Agricultural greenhouse heating， warm water breeding， irrigation and other aspects Shi Yan Xing Kaifagongzuo， made some 译文：世界上最古老的能源之一。据测算，地球内部的总热能量，约为全约煤炭储量的7亿倍。每年从地球内部经地表散失的热量，相当于1000亿桶石油燃烧产生的热量。 关于地热的来源，有多种假说。一般认为，地热主要来源于地球内部放射性元素蜕变放热能，其次是地球自转产生的旋转能以及重力分异、化学反应，岩矿结晶释放的热能等。在地球形成过程中，这些热能的总量超过地球散逸的热能，形成巨大的热储量，使地壳局部熔化形成岩浆作用、变质作用。 现已基本测算出，地核的温度达6000°C，地壳底层的温度达900－1000°C，地表常温层（距地面约15米）以下约15公里范围内，地温随深度增加而增高。地热平均增温率约为3°C/100米。不同地区地热增温率有差异，接近平均增温率的称正常温区，高于平均增温率的地区称地热异常区。地热异常区是研究、开发地热资源的主要对象。地壳板块边沿，深大断裂及火山分布带等，是明显的地热异常区。 普查勘探地热资源，一般采用地表地热调查、钻探和各种物探方法。近年来红外线遥感技术在勘查中取得显著效果。20世纪末，地热资源的开采对象，主要是埋藏浅、热储量大、有流体（地下水或人工灌水）把热能传引到地表的湿地热田。干热岩地热资源和低温湿地热田的开发利用处在研究试验阶段。 中国的地热资源丰富，有悠久开采历史，以往主要利用温泉洗浴治病。1970年后，在广东丰顺、河北怀来、天津和西藏等地曾进行地热发电、建筑物采暖、农业温室采暖、温水育种、灌溉等多方面试验性开发工作，取得一定成果。
