新能源优点英语作文

新能源优点英语作文，关于这个主题相信你已经文思泉涌，作文的评判标准不应该是死板的，作文在现实生活中的意义已经远超于作业的范畴，下面就是新能源优点英语作文的优秀范文参考。

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。

近二十年来，以振动为主要原因造成的恶性事故相继发生，给国家造成了巨大经济损失。而且，振动问题目前仍是新投运大机组不能按期并网、正常投运的主要原因，在机组正常运行期间，振动问题连续不断，影响到正常生产，经常出现机组减负荷和带病运行的情况，甚至使机组被迫停机处理，这些事故屡见不鲜。本系统基于LabVIEW虚拟仪器软件平台，对汽轮机振动信号进行读取加窗，并进行谱分析及自相关分析。LabVIEW虚拟仪器就是在以通用计算机为核心的硬件平台上，由用户设计定义、具有虚拟前面板、测试功能由测试软件实现的一种计算机仪器系统。本系统主要完成了对汽轮机振动信号进行读取，对信号进行矩形窗、汉宁窗、海明窗的加窗选择，然后分别进行信号的幅值谱、功率谱、相位谱分析及自相关分析，并且具有图形操作及显示界面。系统运行结果证明，本系统能够完成对信号的读取，并进行三种窗函数及各种分析的动态选择，并用图形显示结果。Over the last 20 years, mainly due to the vibration caused by the fatal accidents occurred one after another, inflicting huge economic losses.

Coal and oil, used to heat homes and factories and to generate electricity, contain small amounts of sulfur. When the fuels are burned, sulfur dioxide, a poisonous gas, is produced. It is irritating to the lungs. Some cities have passed laws that allow coal and oil to be burned only if their sulfur content is low.汽车不是唯一的空气污染。煤炭和石油，用于家庭取暖和工厂，并产生电力，含有少量的硫。当燃料燃烧，二氧化硫，一种有毒气体，就产生了。它是刺激到肺部。一些城市已通过法律，允许煤炭和石油只有在其被烧毁硫含量低。Most electricity is generated by steam turbines. About half of the sulfur dioxide in the air comes from burning fuel to make steam. Nuclear power plants do not burn fuel, so there is no air pollution of the ordinary kind. But the radioactive materials in these plants could present a danger in an accident. Also, there is a problem in disposing of the radioactive wastes in a way that will not endanger the environment.大部分电力是由蒸汽涡轮机。关于空气中的二氧化硫，使蒸汽一半来自燃料燃烧。核电厂不烧燃料，所以不存在的那种普通的空气污染。但是，在这些植物的放射性物质可能会提出一个意外的危险。此外，还有一个在放射性废物处置的方式，不会危害环境的问题。Another type of pollution, called thermal (heat) pollution, is caused by both the fuel-burning and nuclear plants. Both need huge amounts of cold water, which is warmed as it cools the steam. When it is returned to the river, the warm water may stimulate the growth of weeds. It may also kill fish and their eggs, or interfere with their growth.另一种污染类型，称为热（热）污染，是造成双方的燃料燃烧和核电厂。双方都需要的冷水，这是温暖，因为它大量的蒸汽冷却。当返回到河边，温暖的水会刺激杂草生长。它也可以杀死鱼，它们的卵，或干扰他们的成长。Physicists are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluting material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.物理学家们正在研究发电对环境损害较小的新方法。与此同时，许多发电厂也在实现现代化以减少污染物质。此外，工程师们尝试设计并找到对环境的损害最小的新的发电厂。Thermal energy and power engineeringThis program is to cultivate both master thermal energy and power engineering professional basic theoretical knowledge, computing skills, but also the ability in various forms of generating power plant, refrigeration and air conditioning, new energy related fields in need of economic management knowledge and ability, can be engaged in the electric power industry related to areas of science and technology application, research, development and management of a senior talents.
