有关新能源研究论文英文

题目：Geothermal resources 正文：Geothermal resources in the world's oldest energy sources. It is estimated that the total thermal energy of the Earth's interior, about all the coal reserves of about billion times. Year from Earth's interior heat loss through the surface, equivalent to 1,000 million barrels of oil burning heat. On geothermal sources, there are several hypotheses. 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 crystal. 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 effect. 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 depth. The average temperature of geothermal is about 3 ° C/100 m rate. 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 anomalies. Geothermal anomaly area is research and development of geothermal resources of the main target. Crustal plate edge, deep fault and the volcanic belt at the other, is obvious geothermal anomalies. Exploration of geothermal resources survey, the general use of surface geothermal survey, drilling and various geophysical methods. Infrared remote sensing technology in exploration in recent years achieved remarkable results. 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 field. Hot dry rock geothermal resources and low-temperature geothermal fields of wetland research development and utilization in the pilot phase. China, rich in geothermal resources, has a long mining history, past the main advantage of hot spring bath treatment. 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 achievements.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。

一、新能源汽车的优点：

1、环保，新能源汽车不采用燃油动力装置，不需要柴油，汽油，而是清洁能源，比如电，太阳能，等，减少二氧化碳的排放。

2、不限号，在大城市新能源汽车是不限号的，更方便出行。

省燃油钱，如果使用燃油费大概6角到8角每公里，然而新能源只需要电费而已。

4、传动效率高，新能源一般采用电机传动效率高。

5、政策补贴，现在的新能源汽车享受政策补贴一辆车还能省不少钱。

二、新能源汽车的缺点：

1、汽车续航里程短，新能源汽车一般都是电动的，电池的蓄电量有限，持续行驶的里程也会受限

2、汽车售后服目前好不成熟，新能源汽车各方面都还在摸索、改善中，对于新能源汽车的售后维修，基本没有很多熟练的维修人员，不能及时维修

3、汽车成本较高，电动车为了能反复充电和续航，必然需要好的电池，好的电机，成本相当高

4、汽车充电难、充电慢，新能源汽车应为受限于各方面的条件，还没有完全普及，充电桩有限。

新能源汽车的优点：

1、节约燃油能源。一般是用天然气、石油气、氢气、电力作为动力。2、减少废气排放，有效的保护环境。电动汽车不产生尾气，没有污染。氢能源汽车尾气是水，对环境没有污染。因为基本属于零排放，所以也在限号范围外。3、效率高。一般新能源汽车采用新技术，新结构，使它的效率更高。4、噪声低。新能源汽车缺点：1、因为新能源汽车处于起步阶段，技术还不是很成熟。所以充电比较慢，需要数小时。2、车辆保有量低，充电、加气、维修等不太方便。而且新能源汽车充电难，因为普及面小。3、续航里程短。一般车辆排量较小，动力不足，不适合长距离行驶。4、价格不低。现在价格在5-10万的新能源汽车，只有纯电动汽车有批量生产，选择性不是太大。

扩展资料:新能源汽车是指采用非常规的车用燃料作为动力来源（或使用常规的车用燃料、采用新型车载动力装置），综合车辆的动力控制和驱动方面的先进技术，形成的技术原理先进、具有新技术、新结构的汽车。新能源汽车包括纯电动汽车、增程式电动汽车、混合动力汽车、燃料电池电动汽车、氢发动机汽车、其他新能源汽车等。

新能源汽车两大阶段:第一阶段是以混合动力汽车为主，燃料电池车等新能源汽车为辅的发展方向，开拓新能源汽车市场。第二阶段是在纯电动汽车技术成熟的'基础上，纯电动汽车逐步替代混合动力及燃料电池汽车以至于完全占据新能源汽车市场，实现零排放的阶段。中国新能源汽车产业始于21世纪初。2001年，新能源汽车研究项目被列入国家“十五”期间的“863”重大科技课题，并规划了以汽油车为起点，向氢动力车目标挺进的战略。“十一五”以来，我国提出“节能和新能源汽车”战略，政府高度关注新能源汽车的研发和产业化。

新能源汽车的优点一：环保

纯电动汽车在运行过程中可以做到零污染，完全不排放污染大气的有害气体。即使按所耗电量换算为发电厂的排放，造成的污染也少于传统汽车，因为发电厂的能量转换率更高，而且集中排放可以更方便地假装减排治污设备。

新能源汽车的优点 二：省钱

2014年，国家和地方政府给予电动汽车最高万元的补贴，这一举措使电池成本居高不下的电动汽车的售价能够下降到与传统汽车相当的水平。而在油价高企的今天，电动汽车的运行费用是要远小于传统汽车的。

新能源汽车的优点 三：噪音小

电动机在运行中的噪音和振动水平都要远远小于传统内燃机。在怠速和低速情况下，电动汽车的舒适性要远高于传统汽车，随着速度的提升，胎噪和风噪成为噪音的主要来源，两者才回到同一水平上。电动汽车的这一特点对于提升汽车的NVH性能无疑会有很大的帮助。

新能源汽车的优点 四：节能

电动汽车的百公里耗电量为15-20kwh，算上发电厂和电动机的损耗之后，百公里的能耗约为7公斤标准煤。传统汽车按百公里耗油量10L计，能耗约为10公斤标准煤。并且在城市的拥堵环境里，电动汽车的节能优势会进一步放大。

新能源汽车的缺点 一：充电难

在国内充电设施建设滞后的情况下，充电是电动汽车所面临的的一大难题。公共场所充电桩的缺乏严重影响了电动汽车的出行。

新能源汽车的缺点 二：续航里程短

受限于电池的容量，目前大多数的纯电动汽车续航里程都在100-200公里。虽然一再有专家说90%的人每日行驶距离不超过50公里，但是中国消费者对续航的要求比美国人更高，因为很少有中国家庭拥有超过1辆汽车，而美国人可以做到一辆纯电动汽车通勤，一辆传统汽车旅行。纯电动汽车可以满足老百姓平时上下班，但是周末外出，节假日出游的需求，又该如何解决呢？

新能源汽车的缺点 三：充电慢

目前大多数充电桩都是慢充桩，一辆车充满需要5-8小时。虽然可以利用夜间休息时间充电，但是如果遇到什么突发情况，纯电动汽车的充电慢的缺点就会凸显无疑。

新能源汽车的缺点 四：售后服务有待加强

电动汽车结构虽然简单，但是由于动力部分和传统汽车相去甚远，在维修起来还是会遇到一些麻烦。第一个问题就是维修技师的缺乏，现在绝大部分的技师能够修传统汽车，但是缺少电器方面的知识，贸然维修电动汽车不但可能造成车辆的损坏，还有一定的危险性。第二个问题是零部件的稀缺，电动汽车生产量和保有量都少，因此零部件少，价格还高。

以上就是由电动邦我给您分析得关于新能源电动汽车的四大优缺点 。 不知道是否对你们有所帮助，不过时代在更新，相信新能源电动汽车以后的发展肯定会越来越好，并且完善功能。
