Chemical energy 是一些化学的能量,例如food和fuels就有chemical energy. 当一个人吃完饭,就会有力量去做一些动作。 例如:拍手 拍手这个动作就把chemical energy (food) 变成kiic energy (拍手) 再变成 sound energy (拍手的声音) 再举例:绿叶吸取阳光制造食物 就是叶子把 light energy (阳光) 变成 chemical energy (food) 总括来说,chemical energy 就多数用成一些能够发放力量的能,所以才称化学能。 希望帮到你^^ 参考: myself & 教科书 chemical energy =(化学能) =>me something can be 消化 Eg. 1)Food povides the chemical energy we need. 2)Fuels=(go into the car)=coal petrol..... ***When they are buuuurnt the chemical energy they contain is charges to other forms of energy!! chemical energy ; Food contains chemical energy . therefore we can get the energy we need from our breakfast. fuel ; coal(煤) and petrol (汽油)also contian chemical energy 参考: BOOK AND ME 一粒电已经系化学能 例子: 食物 化学能唔可以直接使用 一定要由能量转换既过程先可以用 例子: 食物->热能->动能 电->动能 化学能是存在物件中的化学能量 例如:电池..... 食物 参考: me2023-06-16 04:47:351
E-Fuel,一种让内燃机重振雄风的“蓝色药丸”
就像百年前,马车不知道会被内燃机革了命一样,如今的燃油车也甚有被电车取代的趋势。只不过,没了发动机的声浪和换挡的节奏感,开车似乎也没了灵魂,这是不少车迷始终对电动车提不起兴致的原因。当然,在碳中和愿景下,严苛的排放法规,让内燃机的发挥空间已经越来越小了,即便是性能车,也从以前的V8、V6,到如今被砍成只能疯狂压榨性能的4缸机。对于普通家用车来说,采用2.0T高功率发动机的车型,都算得上且买且珍惜。这一切的确预示着内燃机正在走下历史舞台。但即便新能源车在这些政策的推动下发展迅速,也无法在短短几年内彻底取代燃油车,毕竟百年积累的全球内燃机车型的基数十分庞大,想全部更替为电车没那么简单。从长远发展的角度看,未来油车和电车还会有相当长的共存期。那么,要是发明出一种环保点的油,内燃机是不是还可以再挣扎挣扎?你可别不信,还真有可能,目前已经有德国车企在带头做这种合成燃料了。当然,这一切的前提是,这种理论上可以从制造源头实现碳中和的燃料,真的能实现大规模量产,并且成本可控。而加速推动这一能源项目的,很大程度上受欧盟2035年停止销售燃油车的政策影响。这项政策对于以燃油车产业为经济支柱的部分欧洲国家来说,可以说是毁灭性的打击。所以德国带头出来跳反,要求在这一政策下豁免使用电子燃料,也为传统燃油车延续“生命”,提供了潜在的可能。所以不出意外,在新型燃料研发上最早的,正是德国品牌。比如奥迪,早在2011年就宣布了e-gas项目,即e-fuel的前身,并于2014年生产出“e-diesel“的乙醇柴油燃料,率先在奥迪A8 3.0 TDI quattro上使用。之后,奥迪在2017年正式开启对e-fuel的研究设发,项目正是为了应对2030年欧盟严苛的环保法规。同门的保时捷也在研究e-Fuel,希望使其具有标志性意义的保时捷911等仍采用传统内燃机的跑车可以“永葆活力,长青不老”。宝马为了研发e-Fuel,也在3年前投资了名为Prometheus Fuels的能源公司。然后其他一些燃油车基业庞大的老牌车企,听说这一另辟蹊径的方法后,也有跟上。比如日系的丰田、日产、本田,还有供应商博世,都组建了自己的合成燃料研发团队。可见,对于这些传统汽车制造商来说,肯定不想轻易放弃在内燃机领域积累几十年,甚至上半年才 筑起的技术壁垒。而在电动化领域,他们与新兴品牌又难以拉开差距,那么如果能通过环保燃料,从源头解决排放问题,或许真的还能再战几十年。至于这种新型燃料,被称为e-fue,其中的Fuel,顾名思义是“燃料“的意思,而字母E代表“的正是电能,而且是可再生电力。看到这儿,估计有朋友会感到疑惑,作为一种供给发动机,需要烧起来用的燃料,E-Fuel怎么还跟电扯上关系了?这就涉及到它的生产方式有多“环保”了。据了解,目前E-Fuel主要使用三种“原材料”,分别是二氧化碳或一氧化碳、以及氢气。简单来说,它的合成原理,是通过水电解生成的H2,再与CO2催化反应,进而生成的一种液体碳氢链燃料。这个过程中,为了降低排放指标,其中氢气通过“电解水”的方式获得,二氧化碳或一氧化碳,直接从工业废气或是普通空气中采集而来。至于电解水需要大量用到的电力能源,还并非普通的用热力发电生产的电能,而是通过风力发电或水力发电获得。可以看到,e-Fuel整个生产过程,包括原料,都是只采用可再生能源。而且值得一提的是,别看e-Fuel是合成燃料,但它的抗爆震性和动力性基本能达到98号汽油的水准。同时,有害物质排放和污染大大降低。所以基础上符合当前燃料的规范标准,也不会在现有车辆的燃油传输系统、喷注系统、燃烧等方面受到影响。种种优势加持下,E-Fuel似乎确实能够成为传统燃油车的救星。所以理论上,它的确可以从源头显著减少了传统化石燃料燃烧后的二氧化碳排放,以帮助燃油车实现碳中和。而且,如果使用合成燃料,还可以继续使用加油站等现有的设备,保存内燃机现有的产业链。但是在目前,这种合成燃料还需要解决量产和成本的关键问题。一方面是产能。以保时捷目前的E-Fuel工厂为例,年产能只有13万升,对于市场上庞大的燃油需求来说完全是九牛一毛。另一边是价格问题,E-Fuel目前的成本可比普通汽油贵得多。目前欧洲市场E-Fuel的制造成本大概在10欧元/升,换算成人民币大概73.3元,而这还只是制造成本。倘若再算上运输成本和销售利润,市场价超过100块人民币是情理之中。所以说,环保是有代价的。当然,目前车企们仍在努力优化E-Fuel的研发制造,力图在效率、成本上突破。但可预期的情况下,未来E-Fuel的制造成本大概能压到2欧元/升左右,换算一下也得14.7元人民币,零售价接近20元,依然比目前市面上的燃油贵多了。但无论如何,E-Fuel这种合成燃料,依然给了内燃机存活的一丝希望。如今,距离2035年欧盟禁售燃油车还有十多年的时间,倘若E-Fuel的生产制造和成本,能在这期间取得显著突破,那么或许真的能让燃油车“重振雄风”。*部分图片来源于网络,如有侵权请联系删除【本文来自易车号作者买车家,版权归作者所有,任何形式转载请联系作者。内容仅代表作者观点,与易车无关】2023-06-16 04:47:421

石油和天然气是怎样开采的?
Two hundred years ago, the world experienced an energy revolution that launched the Industrial Age. Ever since then, with the rapid increase of population density, the industrialized world"s thirst for energy has more than tripled. Petroleum and natural gas are exploited as versatile and high quality energy products. Uranium is also tapped to fuel nuclear reactors and provide atomic energy.两百年前,全球经历了一场能源革命,由此引发了工业时代的到来。从那时起,随着人口密度的迅速增加,工业国家对于能源的需求成倍成倍增加。石油和天然气被看作是用途多、质量好的能源产品而得到开发,而铀也得以开发,为核反应堆提供燃料并供应原子能源。Cheap energy is the lifeblood of human society. But there is a dark side to the near monopoly of non-renewable fossil fuels like coal, oil and natural gas, along with controversial uranium, to supply our growing energy demands.廉价能源是人类社会的命脉。但是,几乎垄断煤炭、石油和天然气等不可再生化石燃料,以及有争议的铀,以满足我们日益增长的能源需求,还有一个阴暗面。The supply of these fuels is physically limited, and their use threatens our health and environment.

求电热水器的英文资料
Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have many uses.Domestically, water is traditionally heated in vessels known as kettles, cauldrons, pots, or coppers. These vessels heat a batch of water but do not produce a continual supply. Appliances for providing a more-or-less constant supply of hot water are variously known as water heaters, boilers, heat exchangers, calorifiers, or geysers depending on whether they are heating potable or non-potable water, in domestic or industrial use, their energy source, and in which part of the world they are found. In domestic installations, potable water heated for uses other than space heating is sometimes known as domestic hot water (DHW).In many countries the most common energy sources for heating water are fossil fuels: natural gas, liquefied petroleum gas, oil, or sometimes solid fuels. These fuels may be consumed directly or by the use of electricity (which may derive from any of the above fuels or from nuclear or renewable sources). Alternative energy such as solar energy, heat pumps, hot water heat recycling, and sometimes geothermal heating, may also be used as available, usually in combination with backup systems supplied by gas, oil or electricity.In some countries district heating is a major source of water heating. This is especially the case in Scandinavia. District heating systems make it possible to supply all of the energy for water heating as well as space heating from waste heat from industries, power plants, incinerators, geothermal heating, and central solar heating. The actual heating of the tap water is performed in heat exchangers at the consumers premises. Generally the consumer needs no backup system due to the very high availability of district heating systems更多资料:en.wikipedia.*rg/wiki/Water_heatinghome.howstuffworks.c*m/water-heater.htm2023-06-16 04:49:281
高中英语作文:人类活动破坏环境
每年的6月5日是世界环境日,近两年人们越来越重视环境日的宣传,因为人类的活动破坏了我们赖以生存的环境,人类已经意识到环境的改变。让我们行动起来,保护环境人人有责。下面是我为大家整理的一篇关于世界环境日的高中英语作文:人类活动破坏环境。 Some people believe that the Earth is beingharmed(damaged) by human activity. Others feel that human activitymakesthe Earth a better place to live. What is your opinion?Usespecific reasons and examples to supportyouranswer. People have been living on the Earth for thousands of years.Humanactivity influences the Earth. Some people believe that theEarth isbeing harmed by human activity. Others feel that humanactivitymakes the Earth a better place to live. In my opinion, theearth isbeing damaged by human activity. There are manystatementssupporting my opinion. Human activity has damaged natural environment and almostexaustednatural resources. Modern industry needs more and moreresources,including minerals, fuels and water. So we confront ofthe seriousproblems such as the lack of fuels and water.Ecological balance isdamaged because factories occupy many placeswhere animals andplants live. More and more buildings areconstructed and forestsbecome less and less. If we cannotrecognize these problems andsolve them soon, we would finally losethe environment suitable forour living. An other serious problem is the green-house effect.Humanactivity decreases forests and increases the usage of fuels sothatthe gas of carbon dioxide is output more and more and there arenotenough plants to absorb it. The green-house effect is moreobviousand more sensible these years. Due to the effect, icebergsin thesouth polar and north polar melt and the sea level becomeshigherthan before. I am worried about the cities nearby the sea andhopescientists find an effective method to eliminate thegreen-houseeffect. Although we have advanced machines and our life seemsmorecomfortable than before, we have less chances to approachnaturesand less spaces to act. The cities become bigger and if wewant tohave a picnic with our friends, we have to drive a longdistance tofind a natural place. In fact, the spaces of humanactivity arebeing damaged by the skyscrapers and factories. From the above statements, we can conclude that humanactivitybrings the Earth many damages. Fortunately people haverecognizedthe point and I believe that the Earth will become abetter placeto live with our ceaseless efforts.2023-06-16 04:49:471

The Cause: ( Acid rain is caused by *** oke and gases that are given off by factories and cars that run on fossil fuels. When these fuels are burned to produce energy the sulfur that is present in the fuel bines with oxygen and bees sulfur dioxide; some of the nitrogen in the air bees nitrogen oxide. These pollutants go into the atmosphere and bee acid. ) -Sulphur dioxide It is the primary cause of acid rain. Sulphur dioxide is released from burning of fossil fuels and industrial plants. -Nitrogen oxides It is another cause of acid rain. Nitrogen oxides are released from vehicles and power plants. Effects: -Vegetation Acid rain washes away esssential nutrients that the plants are in need. In adition it makes the soil acidic and aids the release of aluminium and copper ions which are harmful to plants. -Aquatic life When pH is less than 4.5 calcium metaboli *** in fresh water fish will be affected leading to poor health and stunted growth. As a result diversity and population of some fish species will be reduced. -Building materials Acid rain will cause damage to mon building materials (such as limestone and marble) statues and monuments Many metals will bee oxidised.

How to Solve Energy Crisis 120字的作文拜托了各位 谢谢
Man is faced with a grave problem—the energy crisis, which is becoming increasingly serious. First, with the increase in the world"s population, the demand for fuels is growing steadily. Second, the rapid development of industry and agriculture calls for an increasing amount of coal, oil and natural gas. Confronted with the energy crisis, we should take a series of effective measures to save energy. For one thing, it is high time that people all over the world realized the severe fact that our natural resources have been fixed since the earth was created. For another, the governments of all countries are supposed to lay down the rules and regulations to restrict the amount of gas used by cars. Finally, scientific researches should be encouraged to work out efficient methods of saving fuels and to seek new sources of energy. Personally, I believe that solar energy is a possible source of clean, inexpensive and abundant energy. It does not pollute the environment and costs only as much as the installation of solar panels to absorb the sun"s rays.

易车讯 日前,我们从保时捷官方获悉,保时捷与西门子能源联合多家公司,在智利彭塔阿雷纳斯建立一座生产近碳中和燃料(eFuels)的工厂开启动工,预计2022年中启动生产。保时捷发起该示范项目,并将在其内燃机车型中使用eFuels燃料,保时捷表示:911是eFuels最适配的车型,当然,其他深受客户喜爱的经典车型也将与eFuels适配。目前,这一可再生燃料的相关测试进展十分顺利。eFuels将有望使内燃机的二氧化碳排放量减少高达 90%。此外,保时捷将从2022年起,在保时捷美孚1号超级杯的赛车中率先使用这一产自智利的燃料。“Haru Oni” 项目选址智利南部麦哲伦省(Magallanes),利用当地完美的风力气候条件和低成本的绿色风能,生产这一近碳中和的燃料。生产过程的第一步,电解器利用风能将水分解为氧气和绿色氢气;随后,将从空气中过滤出的二氧化碳与绿氢结合,形成合成甲醇,最终将其转化为eFuel。该试点工厂计划于2022年中启动生产,预期2022年可生产约13万升eFuels燃料。此后,工厂产能将分两阶段扩大,到2024年产能可达约5,500万升,2026年达到5.5亿升左右。2023-06-16 04:51:501

为什么说能源是经济的命脉?
Two hundred years ago, the world experienced an energy revolution that launched the Industrial Age. Ever since then, with the rapid increase of population density, the industrialized world"s thirst for energy has more than tripled. Petroleum and natural gas are exploited as versatile and high quality energy products. Uranium is also tapped to fuel nuclear reactors and provide atomic energy.两百年前,全球经历了一场能源革命,由此引发了工业时代的到来。从那时起,随着人口密度的迅速增加,工业国家对于能源的需求成倍成倍增加。石油和天然气被看作是用途多、质量好的能源产品而得到开发,而铀也得以开发,为核反应堆提供燃料并供应原子能源。Cheap energy is the lifeblood of human society. But there is a dark side to the near monopoly of non-renewable fossil fuels like coal, oil and natural gas, along with controversial uranium, to supply our growing energy demands.廉价能源是人类社会的命脉。但是,几乎垄断煤炭、石油和天然气等不可再生化石燃料,以及有争议的铀,以满足我们日益增长的能源需求,还有一个阴暗面。The supply of these fuels is physically limited, and their use threatens our health and environment. Multiple international treaties have been proposed to limit the use of fossil fuels for this very reason. 这些燃料的供应实际上是有限的,它们的使用威胁到我们的健康和环境。为此,已经提出了多项国际条约来限制化石燃料的使用。Fears of global warming aside, burning fossil fuels releases chemicals and particulates that can cause breathing problems, cancer as well as brain and nerve damage. Nuclear energy, once hailed as"too cheap to meter", has never been economically successful when all costs are factored in.抛开对全球变暖的担忧不谈,燃烧化石燃料会释放出化学物质和微粒,导致呼吸问题、癌症以及大脑和神经损伤。核能曾被誉为“太便宜,无法计量”,但如果将所有成本都考虑在内,它在经济上从未取得成功。Furthermore, public opinion polls show nuclear energy is too closely associated with disasters like the Chernobyl reactor meltdown and the Fukushima explosion, and with the danger that: rebel insurgents could do damage with the toxic waste.此外,民意调查显示,核能与切尔诺贝利(Chernobyl)反应堆熔毁和福岛(Fukushima)爆炸等灾难有着太密切的联系,而且还存在着这样的危险:反叛分子可能用有毒废料造成破坏。Inexpensive and seemingly abundant non-renewable energy from dead plants and extinct animals fueled the 20th century economy, but geologists, climatologists,environmentalists, and many others are warning that the honeymoon may soon be over.从死去的植物和灭绝的动物身上获得的廉价且看似丰富的不可再生能源推动了20世纪的经济发展,但地质学家、气候学家、环境学家和许多其他人警告说,蜜月可能很快就结束了。扩展资料主要考察的是过去完成进行时的知识点:用法:表示过去某一时间之前一直进行的动作。过去完成进行时表示动作在过去某一时间之前开始,一直延续到这一过去时间。和过去完成时一样,过去完成进行时也必须以一过去时间为前提。I had been looking for it for days before I found it.这东西我找了好多天才找着的。They had only been waiting for the bus a few moments when it came.他们只等了一会儿车就来了。表示反复的动作。He had been mentioning your name to me.他过去多次向我提到过你的名字。You had been giving me everything.你对我真是有求必应。常用于间接引语中。The doctor asked what he had been eating.医生问他吃了什么。I asked where they had been staying all those days.我问他们那些天是呆在哪儿的。接具有“突然”之意when句。I had only been reading a few minutes when he came in.我刚看了几分钟他就进来了。She"d only been reviewing her lessons for a short while when her little sister interrupted her.她温习功课才一会儿,她妹妹就打断她了。I had been sleeping when my friend telephoned me.我正在睡觉时,我的朋友给我打电话。2023-06-16 04:53:151
玉米是什幺食物?
If you are what you eat, and especially if you eat industrial food, as 99 percent of Americans do, what you are is "corn."Take a typical fast food meal. Corn is the sweetener in the soda. It"s in the corn-fed beef Big Mac patty, and in the high-fructose syrup in the bun, and in the secret sauce. Slim Jims are full of corn syrup, dextrose, cornstarch, and a great many additives. The “four different fuels” in a Lunchables meal, are all essentially corn-based. The chicken nugget—including feed for the chicken, fillers, binders, coating, and dipping sauce—is all corn. The french fries are made from potatoes, but odds are they"re fried in corn oil, the source of 50 percent of their calories. Even the salads at McDonald"s are full of high-fructose corn syrup and thickeners made from corn.Overproduction sooner or later leads to overconsumption, because we"re very good at figuring out how to turn surpluses into inexpensive, portable new products. Our cheap, value-added, portable corn commodity is corn sweetener, specifically high-fructose corn syrup. But we also dispose of overproduction in corn-fed beef, pork, and chicken. And now we"re even teaching salmon to eat corn, because there"s so much of it to get rid of.How do we begin to change this system? First, we all need to begin to pay attention to the Farm Bill, working to develop farm programs that allow farmers to stay in business without falling into the trap of overproduction. Most city people don"t realize the stake they have in it. They assume it"s a parochial concern of members of Congress from farm states, but it"s not. If it were called the Food Bill, I think we would all pay a lot more attention to it, and get a saner result. The Farm Bill sets out the rules of the game that everyone is playing in, whether you"re an industrial or an organic farmer, whether you"re eating industrially or not.根据实际情况调整内容,希望能够帮到你【ABC.Snap】2023-06-16 04:53:312
可再生能源(Renewable Energy)
全球可再生能源的使用正逐渐增加,这对于应对气候变化可能是一个关键。 可再生能源,就是指能源本身可以自然再生(replennish),永不枯竭的能源,最为常见的有太阳能,风能,水能,地热(geothermal),生物能(biomass)。人类大部分使用的为化石燃料(fossil fuels),但可再生能源的使用率增长最快。 它有以下3个优点: (1)应对气候变化,可再生能源的使用不会直接产生温室气体,产生温室气体主要是在其制造过程中例如制造,安装,操作等,但在过程中排放量很小 (2)减少污染,减少对人体健康的威胁。风能水能太阳能的使用不会造成空气污染,相较于不可再生资源,地热和生物能造成的污染要少得多 (3)可靠:可再生能源永不枯竭,一旦建成,操作成本非常低,消耗的资源也是免费 但可再生能源也有以下3个缺点: (1)不能大规模发电 (2)大坝和风力发电厂的建设会破坏野生动物的生活及其迁徙模式(migration pattern),破坏生态 (3)不稳定(intermittent),太阳能和风能的利用依靠自然,电池储存能源也非常昂贵 一方面,可再生能源的使用既有挑战,但也提供一种替代化石燃料的方式,使用可再生能源不会产生温室气体,无污染,更环保。先进的科技使可再生能源易获取,可负担,更高效,应对气候变化将会变得触手可及。 (关注每天一起学习充电)2023-06-16 04:54:201

中石油职称英语阅读理解文章讲解
中石油职称英语阅读理解文章讲解 在今后的1000年里,我们的世界会面临哪些问题呢?下面是我整理的中石油阅读理解:21世纪的趋势,希望能帮到大家! Trends for 21st Century 21世纪的趋势 1.What problemswillour world encounter in the next1,000 years? Social scientistsand economists, farming experts and environmentalists posethis question and examinedata and informationfrom surveys. 1、在今后的1000年里(in the next1,000 years),我们的世界会面临哪些问题呢?(特殊疑问句语序; encountervi. 遭遇)社会科学家、经济学家、农业专家和环境保护主义者提出(pose)了这个问题,并对调查所得的数据和信息(data andinformation from surveys)进行了研究。 2. In every field, experts examine changes to understandthe state of the field.To understand a country"s economy,economistscheck growthin an industrysuch assteel.To understand the state ofbusiness, they maylook atthe number of building permitsfornew houses. The informationlearnedshows increases or decreases. Important trends emergein each field. 2、各个领域的专家都通过对变化的研究来了解该领域的状况。为了了解一个国家的经济状况(To understand a country"s economy),经济学家对某个行业,如(such as)钢铁业的增长情况(growth)进行调查。为了了解行业的状况(To understand the state of business),他们可能会调查新房建造许可证的发放数量(the number of 数量;buildingpermits 施工执照;建筑许可证)。得到的资料(learned过去分词作定语,修饰the information)能显示出增长或减少的情况,各个领域的重要趋势就能体现出来(emerge vi. 显现;浮现;暴露)。 3. Population 3、人口 4. Population is importanttoevery person on Earth. Peopletendto live longerin most places. In Central Europe,however,life spanis droppingbecausehealth careis notwhatit was a few years ago. Factorsaffectinggeneral healthinclude excessive smoking,drinking ofalcoholandpolluted water supplies. 4、人口多少对地球上的每个人都很重要。在大多数地区(in most places)人们的寿命越来越长(tend to dosth. 倾向于;往往会)。但在中欧,由于卫生保健(health care)不如前几年,人的寿命(life span)正在缩短(is dropping)。影响大众健康(affecting general health)的`因素包括吸烟过度(excessive smoking),酗酒以及饮水污染(alcohol n. 酒精;polluted adj. 受污染的; watersupplies 供水)。 5. The population explosiononour planethas been increasingat an alarming ratebutthe percentage of increaseis decreasing.One out of every five peopleon Earth is Chinese,yetChina"s growth ratehas slowed.Asthe number of womengoingto schoolincreases, the growth rate declines. 5、我们星球上的人口的爆炸正在以惊人的速度(at an alarmingrate)加剧着,不过增长的百分比(the percentage of increase)在减小。地球上每五个人中就有一个(One out of every five people)是中国人,但中国的人口增长速度己经减慢了。随着(as)受教育(going to school修饰the number ofwomen)的妇女越来越多,人口增长率正在下降。 6. FoodProduction 6、粮食生产 7. The production of grainseemsto be decreasingmainlybecauseof climate changes. Natural disasterslike storms and floodshavewashed awaymany crops. 7、谷物产量似乎正在减少,这主要是由于气候的变化。暴风雨(storms)和洪水(floods)这类自然灾害(natural disasters)毁掉了许多庄稼。(wash away 冲走;冲垮) 8.With lessland forcattle and sheep,less meat like beefand lamb is being produced. Production of chicken, turkey and fishhas increased,however. The amount of ocean fishhas not increased,butfish farm productionhas. 8、由于(with)可供饲养牛羊的土地减少了,牛肉和羊肉生产越来越少(less meat like beef and lamb is beingproduced现在进行时被动语态)。不过鸡肉、火鸡肉和鱼的产量提高了。但海鱼(ocean fish)的产量没有提高,只是人工养鱼场(fish farm)的产量提高了。 9. Fish farming is veryefficient:producing a kilogram of fish utilizesless than2 kilograms of feed.In contrastittakes2.2 kilograms of feedtoproduce 1 kilogram of chicken. Onekilogram of beefrequires7 kilograms of grain. People,therefore, may eatless red meatinthe future andmore fish. 9、养鱼业(fish farming)的生产效率相当高(efficientadj. 有效率的):生产1公斤鱼只需要不到2公斤的饲料(less than 少于;小于;不超过;utilize vt.利用),而(in contrast 与此相反;相比之下)生产1公斤鸡肉需要2.2公斤的饲料,生产1公斤牛肉需要7公斤谷物(grain)。因此,人们将来可能会少吃红肉(牛肉、羊肉等)(less red meet),多吃鱼类(more fish)。 10. Energy 10、能源 11.Usingfossil fuelsfor energyhas not changed very muchbutwindenergy useis increasingsignificantly. Denmark, Germany, the Netherlands, Britain, and America havelarge wind power projects. China, India,Mexico, New Zealand, and Ukraine are also developing wind power. 11、以化石燃料为能源的情况(Using fossil fuels for energy)没有发生多大变化,但是(but)对风力的利用正越来越受到重视(is increasingsignificantly)。丹麦、德国、荷兰、英国和美国都有大型风力发电项目(large wind power projects)。中国、印度、墨西哥、新西兰和乌克兰也正在开发风力发电。 12. Energy fromnuclearpower plantsissteadily increasingbutthe problem ofdangerous wastelimits growthin many regions.Becausemany electrical companies consider nuclear energytoo expensive,the trend istowardless dangerous sources of energy. 12、核电厂(nuclear powerplants)提供的能源在稳步上升,但因为核电厂的有害废料(dangerous waste)问题,在许多地区其发展受到限制。由于许多电力公司都认为核能代价太大(too expensive太昂贵),因此总体趋势是发展危险性小的能源(less dangerous sources of energy)。 13.Whilenatural gasuse is increasing,use of coalas fuelis decreasing. Naturalgas, an outstandingenergy source,can be used to heat homes, make electricity, and power cars. 13、随着(while)天然气使用量的增长,煤炭作为燃料的使用量(use of coal as fuel)正在减少。天然气这种优质的(outstandingadj. 杰出的)能源可以用于家庭取暖、发电和驱动汽车。(be used to dosth. 被用来做…) 14. Economics 14、经济 15.Ascountriesaround the world trademore withone another,more products are available.Butthefast development of the world economywillbring aboutmany new problems.Withfewer trees, the paper industry is producing more paper fromrecycled materials.However,the paper-making processunfortunately damages the planetasit useslarge amounts of water, burnsfossilfuelsand produces large amounts ofchemicalwaste. 15、随着(as)世界各国之间贸易量的增加(one another 彼此,通常为三者以上;each other 彼此,通常为两者之间; trade vi. 交易),可买到的产品越来越多(be available 可供使用的)。但世界经济的快速发展会带来许多新问题(bring about 引起;导致)。由于树木减少,造纸厂更多地依靠再生材料(recycled materials)造纸,但不幸的是(unfortunately),造纸工艺(the paper-making process)也对我们的星球造成损害(damages),因为(as)它要用大量的水,燃烧大量的化石燃料(fossil fuels),而且还会产生大量的化学废料(chemical waste)。 16. Automobile productionisdown,whilebicycle productionis up. Crowded highways,high gasoline costs, and ease of bicycling are three reasons forthis change. 16、汽车产量在下降,而(while)自行车产量在上升。导致这一变化的三个原因是:高速公路拥挤不堪(crowded adj.拥挤的),汽油价格昂贵,而骑自行车出行轻便自如(ease n. 轻松;悠闲)。 17. Health 17、健康 18.Three major health trendsexistaswe begin the new century. Health careis better thanever.Medical research breakthroughs includefinding tumors earlyand saving livesthrough CAT scans and surgery. Surviving cancer is a new trend. HIV/AIDS,however,is spreadingquicklyall over the world. 18、在我们迈入新世纪之际,呈现出了三个主要的健康趋势(three major health trends)。(1)卫生保健工作不断改善(better thanever 好于以前),(2)医学研究领域有新的突破(breakthrough n. 突破;突破性进展),包括利用CAT扫描(即计算机化X射线轴向分层造影扫描)和外科手术(surgery n.)来及早发现肿瘤并挽救生命(findingtumors early and saving lives)。癌症病人的生存率得到提高也是一个新趋势。然而,艾滋病(HIV/AIDS)却正在全世界迅速蔓延(spread vi. 传播)。 19. The third major trend istowardan attitude of indifference. Peopleseem to have forgottenwaysto keep diseases under control.Althoughmedical sciencehad achievedcontrol overseveral dangerous diseases,some are returning. For instance, tuberculosis, once a dangerous killer, was cured. Now the disease is appearingagain. 19、(3)第三个趋势是人们的态度变得越来越无动于衷。人们似乎已经忘记了(seem to have forgotten 不定式的完成时形式)如何控制疾病(to keep diseases under control不定式作定语,修饰ways)。虽然(although)医学早已能够控制若干危险的疾病(control over 控制;支配;征服),有些病却正在卷土重来(some are returning)。例如(for instance),曾经是危险杀手(once a dangerous killer)的肺结核原本已被消灭(was cured),而现在这种疾病又死灰复燃了。 20. Nature 20、自然 21. Pollutioncontinuesto affect our forests and water.The bird population is decreasingbecause ofoil spills and spreading cities. Seas and oceans are changing.Treesarecut down, more soilwashesaway, and water qualityis affected.Many of these trees are in our rain forestswhere thick areas of plants and trees, home for many birds andanimals,aredisappearing. 21、污染不断破坏着我们的森林和水源(continue to do sth.; continue 后接不定式作宾语)。由于(because of)海上石油泄漏(oil spills; spill n. 溢出)和城市不断扩大,鸟类的数量正在减少。海洋在改变,树木遭砍伐(被动语态;cut-cut-cut;cut down 消减;砍倒;wash away 冲走),越来越多的泥土被冲走,水质(water quality)受到了影响(被动语态)。许多热带雨林中的树木遭到砍伐,那里茂密的(thick)植物和树木原本是许多鸟类和动物的家园,现在却正在消失。 22. Conclusion 22、结论 23.Ourchallengesfor this new centuryare clear. The problems ofnumerousinhabitants onthis small planetwill continue to be important toeach of us. These challenges showthatall of usneedtobeinvolved insolving the problems.May wefind new waystoaccomplish the task? 23、在新世纪中,我们所面临的挑战是显而易见的(clear)。在这个小小星球上(on this small planet)的很多人面对的问题(the problems of numerous inhabitants; numerousadj. 许多的; inhabitantn. 居民;居住者)仍将是关系到我们每个人(each of us)的重大问题。这些挑战表明,我们所有人(all of us)都必须参与解决这些问题(need to do sth. 需要做某事;be involved in参与,被卷入…中;涉及到…)。但愿我们(may we)能找到新的途径去完成这一使命(to accomplish the task不定式作定语,修饰new ways)。 关于本文的两点说明: 在做“阅读理解题”时,需要特别注意but, however,while, although等“转折连词”,理解它们前、后句子所要表达的意思。 as在本文中出现了几种不同用法,as可是考试中的“大热门”。 conj.(连词):因为;随着;虽然;当…时 As(随着)the number of women going to school increases, the growth rate declines.

Wald)翻译 赵学庆如果你有机会来到美国南达科他州苏福尔斯机场的候机大楼,不妨趁着行李运到前的空闲四处参观一下。一辆绿白相间的印地赛车(Indy)穿梭在几条行李传送带之间,车身上的贴花图案标明它以乙醇(ethanol)作为燃料;在租车公司的摊位前,有一个醒目的标志,提醒客户不要给出租车加注E85——当地出售的超级乙醇混合燃油,这种混合燃油会损坏出租车引擎,因为当地的出租车并不是为这种混合燃油而设计的。乙醇之乡苏福尔斯,是美国将碳水化合物(carbohydrate)转变为碳氢化合物(hydrocarbon)的推广中心。在美国,乙醇热潮持续高涨,甚至开启了一个燃油转换过渡期,规模之大,恐怕只有40年前电力行业建造的数百座核电厂方可媲美。2005年8月,美国国会通过了一项重要能源法案,要求到2012年,将乙醇年产量从2005年时的40亿加仑左右增加到75亿加仑(1加仑约等于3.8升),以便取代进口燃油。业界人士认为,在美国政府的税收优惠和补贴政策扶持下,特别是如果油价仍然居高不下,那么这一目标的实现有望大大提前,因为将农作物转化为乙醇的成本,远远低于2006年秋天的汽油零售价——每加仑2.50美元。实际上,据美国可再生燃料协会(Renewable Fuels Association)介绍,2006年美国的乙醇产量超过50亿加仑。与每年约1,400亿加仑汽油和柴油消耗量相比,虽然这一数量还显得微不足道,但是乙醇产量在一年内却增长了50%。美国能源部(DOE)负责能效和可再生能源的副部长安迪·卡斯纳(Andy Karsner)称,由于高油价增加了乙醇的市场吸引力,开发商纷纷修建乙醇工厂。他断言美国将出现一个乙醇繁荣期,“类似于19世纪50年代宾夕法尼亚州的石油热”。这股热潮真能给人们带来好处吗?实际上,我们生产乙醇的方式并没有多大优势。美国所有的商业乙醇燃料都用玉米粒制造,采用能量密集型的生产方式。一些研究表明,炼制一加仑乙醇所耗用的能量,甚至高于它燃烧时所提供的能量。即使一些支持玉米乙醇的研究,也只能证明它的能源净收益微乎其微;另一种持反对意见的研究则表明,同原油-汽油循环比起来,玉米-乙醇循环在减少温室气体方面的作用,几乎可以忽略不计。在乙醇生产厂商完善纤维素(cellulose)乙醇生产方法之前,玉米乙醇毫无经济或环保意义。纤维素是组成玉米秆、树木及其他草本植物草茎的木质成分,对它的管理和收割只需要耗费较少的能源。但是,虽然科学家知道某些基于生物学的加工方法,可以转化纤维素中的糖分,但是一些试图生产纤维素乙醇的公司,迄今也未能形成商业规模的批量生产。甘蔗是最佳植物能源,它所拥有的可用于制造乙醇的糖分含量,远远高于玉米秆和草本植物中的含量,但是美国缺乏巴西那样的气候条件和廉价劳动力,无法对甘蔗进行开发利用。要实现用纤维素生产乙醇,就需要对农业生产和工业生产工艺进行重大改进。否则,乙醇仍将是几乎没有任何净收益的、难于利用的产品,美国也将继续依赖进口石油。玉米乙醇:可再生能源?不少人一直把用玉米生产的乙醇视为“可再生能源”。据最新调查统计,生产一加仑玉米乙醇可谓“入不敷出”,所耗用的其他能量(如天然气、柴油)几乎接近或甚至高于它所产生的能量。况且,各生产环节中排放的二氧化碳,也有悖于“清洁能源”的初衷。美国生产的大部分乙醇,都被用作汽油的一类添加剂,它可以按1∶9的比例与汽油混合使用,这是普通引擎能够使用这种混合燃油而不遭致损坏的最高比例。在有些地区,主要是在农业区,驾驶员能够购买到E85混合燃油,这种混合燃油含有85%的乙醇和15%的普通无铅汽油(unleaded regular gasoline),主要供专门设计的“柔性燃料”(flexible fuel)引擎使用。对于普通引擎而言,乙醇与蒸馏酒中所含的酒精一样,会腐蚀掉引擎和燃油系统中的密封件。数百万辆汽车都装备了这种引擎(不过许多车主都并不知情),然而E85销售点却只有几百个,而且目前这一燃油供应链的扩展速度极为缓慢。尽管如此,玉米乙醇仍然发展迅猛,部分原因在于,在美国华盛顿哥伦比亚特区,它拥有一支由农业州参议员和众议员组成的强有力的两党支持者队伍。此外,它还得到了一些非农业州地区人士的支持,这些人认为美国应减少对进口石油的依赖。由于玉米能年复一年栽种和收获,鼓吹者便认为乙醇是一种可再生燃料。美国可再生燃料协会还印发了一本装帧精美的宣传小册子,暗示每年消耗75亿加仑乙醇,就意味着少进口1.79亿桶外国石油。这一水平大约相当于美国15天的石油进口量——虽然不能“药到病除”,但至少开了一个好头。然而,这只是玉米乙醇的表面风光而已,实际上它仍有不少问题。第一个问题在于,一标准桶(42加仑)乙醇只相当于大约28加仑汽油,因为一标准桶普通无铅汽油含有约11.9万英热单位(Btu,1英热单位约为1,055焦耳)能量,相比之下,一标准桶乙醇只含有8万英热单位能量。因此你给油箱加满E85混合燃油时,其实只相当于加了2/3油箱的汽油。即使一加仑乙醇的售价更为便宜,但要行驶一加仑汽油所能行驶的里程,你必须购买更多的乙醇。第二个问题则在于,美国缺少生产乙醇所需要的某些资源。美国的玉米资源确实丰富,玉米地从苏福尔斯机场四周一直连绵延伸到远方。但制造乙醇需要耗费大量的天然气。燃油用乙醇的生产方法与酒用乙醇的制造方法基本相同。酵母(yeast)消耗掉糖分而释放出酒精和二氧化碳,所获得的产物经过蒸馏,让酒精蒸发,然后将酒精收集起来加以冷凝。各个生产环节都需要用天然气来加热。目前,生产一加仑乙醇(含有8万英热单位能量),需要大约3.6万英热单位的天然气。20世纪90年代,美国国会力图通过一些法案,鼓励乙醇制造厂商生产更多乙醇,支持一些农业州的经济发展。当时天然气较为便宜,每百万英热单位的天然气平均价格约为3美元,而到2005年冬天,天然气价格已飚升至14美元。此外,高需求量必然会刺激天然气价格向上攀升。虽然乙醇支持者认为乙醇燃料是未来可持续能源的一个组成部分,但是耗费的大量天然气,却是不可再生的,甚至难以支持现在的需求。美国乙醇产量正在下降,加拿大乙醇产量也满足不了人们的消费需求。具有讽刺意味的是,为了制造“本土”乙醇,美国将不得不从北美洲以外的地区进口更多的天然气。一些乙醇生产厂商正在用煤替代天然气,但这又有悖于人们对于清洁能源和可再生能源的定义。烧煤会释放大量的二氧化碳,这样一来,使用乙醇燃料的汽车对气候变化造成的影响,反而要比原来使用普通汽油的汽车严重得多。理论上讲,一家乙醇生产厂为了生产乙醇,可从电力公司购买电力来提供生产所需热量,但是对于许多美国电力公司来说,那样就可能意味着,要燃烧更多的煤和天然气来满足这一用电需求。生产乙醇还需要一些其他形式的能源。乙醇不像汽油或柴油那样可以用管道来输送,因为这类输送管道很容易进水,虽然水不会与汽油或柴油混合,但是却能与乙醇混合,一旦混合就会破坏乙醇的燃料热值。因此,为了将乙醇运往市场,就需要动用卡车,有时还需要长途运输,这就必须消耗柴油。此外,联合收割机收割玉米作物也要耗用柴油,而种植玉米所用的化肥,其生产过程也离不开天然气。上述一些问题成了计算乙醇“净能量平衡”的关键因素。这一话题引起了人们激烈争论。2005年,美国康奈尔大学的农学教授戴维·皮门特尔(David Pimentel)宣称,制造一加仑乙醇所耗费的能量,超过了它燃烧时产生的能量。一些持相反意见的人则反驳说,皮门特尔几乎没有考虑乙醇副产品的价值,其中一些能够用作家畜饲料(可取代栽种部分用作饲料的玉米),而且他将一些与乙醇无关的能源成本也统统算到了乙醇头上,甚至包括了乙醇工厂工人的用餐成本。但是,这些分析家都一致认为,即使乙醇的净能量值为正,增益也十分微小。同一年,美国生物科学学会(American Institute of Biological Sciences,缩写为AIBS)的一份重要研究报告断定,用玉米生产的乙醇所能产生的能量,仅比生产玉米乙醇所需的能量多出10%左右。与巴西用甘蔗生产乙醇高达370%的能量产出相比,这一数据显然微不足道。据美国阿尔贡国家实验室运输研究中心的环境科学家王全录(Michael Wang)估算,考虑到所有的生产环节——玉米地施肥、玉米收割、将玉米淀粉浆蒸馏为酒精等等,每生产100万英热单位的乙醇,需要耗用74万英热单位的化石燃料。虽然乙醇一直被当作为农产品推广,但它基本上还是化石燃料的产物。在减少温室气体方面,乙醇带来的好处更是微乎其微。在2006年1月出版的《科学》杂志上,美国加利福尼亚大学伯克利分校的能源与资源助理教授亚历山大·E·法雷尔(Alexander E. Farrell)撰文宣称,乙醇在减少温室气体方面的作用“难以确定”。在考察了各种研究报告之后,法雷尔及其合作撰稿人断定,在排放大气污染物方面,用天然气生产的乙醇比汽油产品要稍好一些,但是用煤生产乙醇却更糟糕。燃烧一加仑汽油释放大约20磅二氧化碳(1磅约为450克),其中包括了来自汽车引擎和炼油厂的排放量。尽管乙醇的这一可比数据尚存争论,但到底是稍好一点还是更糟一些,主要取决于乙醇的生产过程。以限制二氧化碳排放量为理由,鼓吹乙醇燃料的说法是靠不住的。2023-06-16 04:56:261

请人翻译一篇英语考试文章,翻译完追加200分(先上分没人答的话分就白上了),谢谢。
这是前部分的人工翻译。。。如果可以的话我再翻最后的一段:E:在1998年,交通运输方面将被责备因为它占了28%的二氧化碳(最主要的温室气体)排放。 据最新估计,如果不采取措施扭转交通增长趋势,从运输的二氧化碳排放量,可以预计在与记录中1990年的739万亿吨相比,2020年将增长约50%,至11130亿公吨,其中公路运输是主要的罪魁祸首,因为其对于二氧化碳排放量的贡献率达84%。因此,使用替代燃料和提高能源效率既是生态必要性也是技术的挑战。问:同时,需要用更大的努力来实现模式转变。这种变化不能一蹴而就,这条路在过去的半个多世纪里不断恶化。这使得今天的铁路货运服务面临边缘化(只有8%的市场份),国际货物列车以平均速度18公里/小时的速度挣扎。(以下)出现了三种可能的方法。G:第一种方法将包括通过独资定价致力于公路运输。此选项将不会和其他运输方式的配套措施的协同。在短期内,由于货运车辆的载货量比率较高,以及由于运输价格的上升,预计乘客车辆的使用率会有所下降,从而抑制公路运输的增长。 然而,缺乏可用于振兴其他运输方式的措施将导致更可持续的运输方式不可能拿起接力棒。2023-06-16 04:57:041
英语演讲稿带翻译:应对日益严重的气候变化威胁
考 网英文写作翻译频道为大家整理的英语演讲稿带翻译:应对日益严重的气候变化威胁,供大家参考:) 奥巴马在例行的周六演说中告诉美国人民,他几天前推出以应对日益严重的气候变化威胁问题的计划。他的计划将减少碳污染,保护我们的国家,免遭气候变化的影响,并引领世界在气候变化灾害中协调一致。 奥巴马每周演讲2013-06-29:Confronting the Growing Threat of Climate Change 中英对照演讲稿 Hi everybody. A few days ago, I unveiled a new national plan to confront the growing threat of a changing climate. 大家好。几天前,我推出了一个新的国家计划应对日益增长的气候变化威胁。 Decades of carefully reviewed science tells us our planet is changing in ways that will have profound impacts on the world we leave to our children. Already, we know that the 12 warmest years in recorded history have all come in the last 15, and that last year was the warmest in American history. And while we know no single weather event is caused solely by climate change, we also know that in a world that"s getting warmer than it used to be, all weather events are affected by it – more extreme droughts, floods, wildfires, and hurricanes. 几十年反复审视的科学告诉我们我们的星球正在改变,这种改变将对我们留给我们的后代的世界产生重大的冲击。我们已经知道历有记录的最热的12年都发生在最近的15年里,去年是美国历最热的一年。尽管我们知道没有一个天气事件是地由气候变化造成的,我们还知道在一个比过去变暖的世界所有天气事件—更多的大旱、洪水、森林大火和飓风,都受它影响。 Those who already feel the effects of a changing climate don"t have time to deny it – they"re busy dealing with it. The firefighters who brave longer wild fire seasons. The farmers who see crops wilted one year, and washed away the next. Western families worried about water that " s drying up. 那些已经感觉到气候变化影响的人们没有时间否认了—他们正在忙于应对它。消防队员们在更长的森林大火季节奋勇灭火。农场主们眼看着他们的庄稼一年枯萎,另一年水淹。西部的家庭担心水资源枯竭。 The cost of these events can be measured in lost lives and livelihoods, lost homes and businesses, and hundreds of billions of dollars in emergency services and disaster relief. And Americans across the country are already paying the price of inaction in higher food costs, insurance premiums, and the tab for rebuilding. 这些事件的损失是用人民的生命财产损失、企业和住房的损失和数以千万计的紧急救援和灾难救济支出来度量的。全国人民已经在以更高的食品价格、保险金和重建开销为这些行动付出了代价。 The question is not whether we need to act. The question is whether we will have the courage to act before it"s too late. 问题不是我们是否需要行动。问题是我们是否有勇气防止病入膏肓。 The national Climate Action Plan I unveiled will cut carbon pollution, protect our country from the impacts of climate change, and lead the world in a coordinated assault on a changing climate. 我推出的第一号全国气候行动计划将减少碳污染,保护国家不受气候变化冲击,引领世界协调地应对气候变化。 To reduce carbon pollution, I"ve directed the Environmental Protection Agency to work with states and businesses to set new standards that put an end to the limitless dumping of carbon pollution from our power plants. We " ll use more clean energy and waste less energy throughout our economy. 为了减少碳污染,我已经责成环境保护署与各州和企业合作制定新的标准来结束发电厂无休止碳污染排放。我们将使用清洁能源和无废物能源来驱动我们的整个经济。 To prepare Americans for the impacts of climate change we can"t stop, we " ll work with communities to build smarter, more resilient infrastructure to protect our homes and businesses, and withstand more powerful storms. 为了让美国人民准备好应对无法制止的气候变化的冲击,我们将与社区合作打造更加智能化、更加弹性的基础设施来保护我们的住房和企业、使其可以抵御更强的风暴。 And America will lead global efforts to combat the threat of a changing climate by encouraging developing nations to transition to cleaner sources of energy, and by engaging our international partners in this fight – for while we compete for business, we also share a planet. And we must all shoulder the responsibility for its future together. 美国将通过鼓励发展中国家实现向清洁能源的转型,共同参与国际合作应对来领导全球应对气候变化威胁的努力—因为尽管我们的企业在竞争,我们仍然共享一个地球。我们必须共同承担它的未来的责任。 This is the fight America can and will lead in the 21st century. But it will require all of us, as citizens, to do our part. We"ll need scientists to design new fuels, and farmers to grow them. We"ll need engineers to devise new technologies, and businesses to make and sell them. We"ll need workers to man assembly lines that hum with high-tech, zero-carbon components, and builders to hammer into place the foundations for a new clean energy age. We " ll need to give special care to people and communities unsettled by this transition. And those of us in positions of responsibility will need to be less concerned with the judgment of special interests and well-connected donors, and more concerned with the judgment of our children. 美国能够也应该领导21世纪的这场战斗。但是它要求我们所有人,作为公民,尽我们的义务。我们需要科学家们设计新燃料、农场主们种植它们。我们需要工程师们构思新技术,企业生产和销售它们。我们需要工人们操作满是高技术、零碳的部件的装配线,建筑工人们为新清洁能源时代奠基。我们需要给予在这场转型中处于困境的人们和社区特殊的关爱。而我们这些在责任岗位的人们需要少考虑特殊利益集团和神通广大的捐赠者们的公平,多考虑孩子们的公平。 If you agree with me, I"ll need you to act. Educate your classmates and colleagues, your family and friends. Speak up in your communities. Remind everyone who represents you, at every level of government, that there is no contradiction between a sound environment and a strong economy – and that sheltering future generations against the ravages of climate change is a prerequisite for your vote. 如果你们赞同我,我想要你们行动。开导你们的同学和同事们、家人和朋友们。在你们的社区呼吁。提醒每一个在每一级政府代表你们的人健全的环境和强劲的经济没有矛盾—保护未来的后代不受气候变化的报复是你们投票的前提。 We will be judged – as a people, as a society, and as a country – on where we go from here. The plan I have put forward to reduce carbon pollution and protect our country from the effects of climate change is the path we need to take. And if we remember what"s at stake – the world we leave to our children – I"m convinced that this is a challenge that we will meet. 我们将作为一个民族、一个社会和一个国家就我们从此走向何方而接受世人的评判。我推出的一号计划旨在减少碳污染、保护我们的国家不受气候变化的冲击是我们的必由之路。如果我们还记得什么至关重要—我们留给后代的世界—我就对这是我们能够战胜的挑战充满信心。 Thank you, and have a great weekend. 谢谢,周末快乐!2023-06-16 04:57:111
gas oil和diesel有什么区别?
Gas Oil确实如热心网友所讲,是原油炼化过程中的一种产品。介于煤油和润滑油之间。Gas Oil 与 Diesel是包含关系,即:Diesel是一种Gas Oil。参考:Major products of oil refineries:-Most products of oil processing are usually grouped into three categories: light distillates (LPG, gasoline, naphtha), middle distillates (kerosene, diesel), heavy distillates and residuum (fuel oil, lubricating oils, wax, tar). This classification is based on the way crude oil is distilled and separated into fractions (called distillates and residuum) u2022 Liquid petroleum gas (LPG) u2022 Gasoline (also known as petrol) u2022 Naphtha u2022 Kerosene and related jet aircraft fuels u2022 Diesel fuel u2022 Fuel oils u2022 Lubricating oils u2022 Paraffin wax u2022 Asphalt and Tar u2022 Petroleum coke2023-06-16 04:57:193
object-c的扩展的关键字
类型声明,类似于c++中的class,区别在于Object c中的声明与实现是强制分开的,@interface关键字用于类型的声明,包括数据成员、方法声明、属性等。方法的参数传递采用中缀符的形式,利用“:”分割参数名和被传递参数,类型的声明以@interface开头,以@end结束,通常一个类型的声明采用下面的结构:@class someOtherObject //外部类型声明@interfacesomeObject:NSObject //继承的类型{int i; //成员变量}-(id)someMethod:(int)someArg someOtherArgName:(int)someOtherArg; //对象的方法+(id)someMethod:(int)someArg; //类方法-(id)init; //初始化方法@propertyint num; //属性@end 对应于@interface的类型声明,@implementation表示一个类型的实现过程,同样以@end结束,实现的格式通常如下:@implementationsomeObject-(id)someMethod:(int)someArg someOtherArgName:(int)someOtherArg{//实现代码}@synthesize num=i; //将属性与变量进行对应@end Object C中的方法调用形式采用消息发送的方式,通常调用的形式如[someObject someMethod:firstArg someOtherArgName:otherArg]实例的初始化也采用消息发送的形式,可以简单的调用类型的new方法来获取一个实例对象,简单实例化的方法通常是:someObject *obj = [someObjectnew]; //类的实例化new方法的实际过程是调用alloc和init方法,因此如果需要采用自定义的方法来初始化实例,则需要自己重写init方法,通常的初始化方式为:someObject *obj = [[someObject alloc] init]; //采用无参数的init实例化someObject *obj = [[someObject alloc] initWithArg:Arg]; //采用参数的实例化 @class是一个前向引用声明,类似于C++中的friend友元声明,其作用是告诉编译器其后面的字段代表一个类型名称,尽管不知道类型的具体实现,但是只需要将其作为一个类型名称处理即可。通常在使用复合的结构时可以采用@class来减少头文件的相互引用,如果出现循环依赖,则需要依靠@class来避免引用的死循环。通常使用形式为:@classsomeOtherObject;@interfacesomeObject:NSObject{someOtherObject *obj;}@end 尽管可以使用obj->arr的形式去强制读取对象的成员变量,但是良好的编程形式是对外界提供成员变量的读写接口。@property关键字提供了外界对成员变量的访问接口,其本质是为某一个属性提供set和get操作。根据不同的需要,可以添加readonly(只读,相当于只添加get不添加set方法)或者readwrite(读写,如果不添加则为默认);还有三种赋值方式可选 :assign(直接赋值,通常用于基本类型),retain(释放旧值,增加新的retaincount),copy(常用于字符串,生成一个新的拷贝)。通常使用的方式如下:@interface someObject:NSObject{int i; //成员变量}@property (assign,readonly) int num; //属性@end 与@property对应,将一个外在属性与成员变量相关联,定义在@implementation中,如果属性名与变量名一致则可以省略变量名。常用方法:@implementation someObject@synthesize num=i;//如果属性名也为i,则可以直接写为 @synthesizei@end Object C采用引用计数的方式进行内存管理,由于所有的对象都继承于NSObject,因此所有的对象都可以接受NSObject的三个方法:-(id)retain;-(void)release;-(unsigned)retainCount;retain方法将对象的引用计数加一并返回该对象,release将引用计数减一,retainCount方法返回对象当前的引用计数。当采用new、alloc、copy方法创建一个对象时,它的引用计数被置为1,如果程序中对该对象进行操作,则应根据需要,通过调用retain和release方法来保证该对象在不需要的时候被清除。当一个对象的引用计数被置为0后,系统会自动向对象发送一个dealloc消息,将其占有的资源释放。通常情况下,如果一个对象的初始化过程调用了其他资源,则应该重写改对象的dealloc过程,保证在对象的销毁期正确释放这些资源。为了更加方便的进行能存管理,cocoa中提供了一个自动释放池(autorelease pool)的概念,每一个类都继承了一个autorelease方法,当调用对象的autorelease方法时,改对象会被加入到开始创建的自动释放池中。当程序进行到不再需要自动释放池中的对象时,将自动释放池释放的时候会向池中的所有对象发送一个release消息,从而保证不再需要的对象被正确的释放。通常的用法如下:NSAutoreleasePool *pool;pool = [[NSAutoreleasePool alloc] init];someObject * obj = [[someObject alloc] init];[obj autorelease]; //加入自动释放池//其他代码[pool release]; //执行该语句时,系统会向池内所有的对象发送release消息;在这个例子中,如果对obj进行的其他retain操作和release操作保持一致的话,则会将obj的引用计数变为0,从而调用它的dealloc方法进行资源释放Object C进行内存管理的3条规则是: 如果使用new、alloc或copy操作获得一个对象,则该对象的保留计数器值为1 如果通过任何其他方法获得一个对象,则假设该对象的保留计数器值为1,而且已经被设置为自动释放 如果保留了某个对象,则必须保持retain方法和release方法的使用次数相等。 类别是为现有的类提供一个新的方法的方法,即使没有一个类的源代码,仍然可以向类中添加一个方法以方便使用。类别的主要目的有3个:将类的实现分散到多个不同的文件或框架中,创建对私有方法的前向引用,向对象添加非正式协议。类别的声明方法:@interfacesomeObject (someProtocal)-(void)someMethod;@end类别的实现方法:@implementationsomeObject(someProtocal)-(void)someMethod{}@end Object C中的协议类似于java中的接口,通过@protocol关键字定义一个或多个需要遵从协议的对象实现的方法,协议定义的方法:@protocolsomeProtocol-(void)someMethod;@end采用协议的方法是在类声明时使用尖括号注明其需要使用的协议:@interfacesomeObject:NSObject <someProtocol>在类实现时需要将协议中规定的方法都予以实现。Object C 2.0增加了2个新的协议修饰符@optional和@required,可以规定协议中的方法是否为必须实现的方法。2023-06-16 04:56:481

芦荟的解释芦荟的解释是什么
芦荟的词语解释是:芦荟lúhuì。(1)一种多年生常绿草本植物(Aloeveravar.chinensis),叶大而肥厚、基出、簇生、狭长披针形,花黄色或有赤色斑点,多产于热带地方。又名“油葱”,叶边缘有尖锐的锯齿,花像穗子,叶汁可入药。芦荟的词语解释是:芦荟lúhuì。(1)一种多年生常绿草本植物(Aloeveravar.chinensis),叶大而肥厚、基出、簇生、狭长披针形,花黄色或有赤色斑点,多产于热带地方。又名“油葱”,叶边缘有尖锐的锯齿,花像穗子,叶汁可入药。拼音是:lúhuì。结构是:芦(上下结构)荟(上下结构)。注音是:ㄌㄨ_ㄏㄨㄟ_。芦荟的具体解释是什么呢,我们通过以下几个方面为您介绍:一、国语词典【点此查看计划详细内容】植物名。百合科芦荟属。为常绿植物,叶肉质而肥厚,叶缘有锐锯齿。产于热带。从叶中采汁,可以入药。二、网络解释芦荟(芦荟属多年生草本植物)芦荟(学名:Aloevera(Haw.)Berg):为单子叶植物纲、阿福花科(又称日光兰科、独尾草科)、芦荟属的多年生常绿草本植物。又名库拉索芦荟、中华芦荟、油葱、洋芦荟、翠叶芦荟、美国芦荟等。叶簇生、大而肥厚,呈座状或生于茎顶,叶常披针形或叶短宽,边缘有尖齿状刺。花序为伞形、总状、穗状、圆锥形等,色呈红、黄或具赤色斑点,花瓣六片、雌蕊六枚。花被基部多连合成筒状。芦荟(即库拉索芦荟)是芦荟属中少数可食用的物种之一,其制品被广泛应用于食品、美容、保健、医药等领域。但芦荟也具有一定毒性,孕妇、婴幼儿不宜食用。普通人每日食用库拉索芦荟凝胶不宜超过30克。对芦荟的过敏反应包括皮肤红肿、粗糙等现象,轻者出现恶心、呕吐、腹泻等症状,重者可引起急性肾炎。“芦荟”一词有时也被用作对芦荟属植物的泛称。(概述图来源:)关于芦荟的单词formaloin关于芦荟的成语闷葫芦依葫芦画瓢荟萃一堂葫芦依样关于芦荟的词语闷嘴葫芦葫芦依样没嘴葫芦明月芦花荟萃一堂掩口葫芦人文荟萃依样葫芦群英荟萃关于芦荟的造句1、虽然开张不到一周时间,已有不少居民带着自家的花卉前来“托管”,目前该站内已有蟹爪莲、龟背竹、芦荟、海棠、文兰等十多种花卉。2、天然护发及草药成分,包括许可的有机芦荟,紫锥花和蜀葵,能使秀发不易缠结。3、选择性地栽种植草,如银苞芋吊兰、芦荟和虎尾兰,对吸收甲醛、净化空气、清除有毒物质都有帮助。4、没错。所以芦荟卖得挺好。这盆儿行吗?5、以芦荟和糯米为主要原料,通过一系列的加工处理,分别制成芦荟汁及甜酒酿。点此查看更多关于芦荟的详细信息2023-06-16 04:57:101
日志出现NSKeyValueObservance错误.怎样解决
您好,很高兴为您解答。如果错误代码如下显示: 2014-01-04 10:40:06.776 HZXS_IPHONE_BETA[2806:60b] Display View. 2014-01-04 10:40:21.168 HZXS_IPHONE_BETA[2806:60b] An instance 0x17b57000 of class UITableView was deallocated while key value observers were still registered with it. Observation info was leaked, and may even become mistakenly attached to some other object. Set a breakpoint on NSKVODeallocateBreak to stop here in the debugger. Here"s the current observation info: <NSKeyValueObservationInfo 0x175dbe00> ( <NSKeyValueObservance 0x175dbdc0: Observer: 0x175db160, Key path: contentOffset, Options: <New: YES, Old: NO, Prior: NO> Context: 0x0, Property: 0x176a1530> )意思大概是:uitableview注册了观察者,然后没有被注销掉,又开始重复使用。由于继承的那个上拉刷新的那个uitableview,没有被注销,可尝试在-(void)dealloc 这里注销看下2023-06-16 04:56:411
uiscrollview 里面内嵌几个button 怎么完美解决点击事件的响应
UISCrollView本身不支持touch,需要重写UIImageView类,响应touch事件,委托给你的类处理,重写UIImageView类代码如下,然后在要添加UIImageView的类中,实现下面代码定义的协议#import <Foundation/Foundation.h>@protocol ImageViewDelegate@optional-(void)TouchesBegin:(NSInteger)imageTag;@end@interface CustomizeImageView : UIImageView {//声明一个代理id<ImageViewDelegate> delegate;}@property (nonatomic,assign) id<ImageViewDelegate> delegate;@end#import "CustomizeImageView.h"@implementation CustomizeImageView@synthesize delegate;- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {//NSLog(@"delegate:%@",self.delegate);[self.delegate TouchesBegin:self.tag];}- (void)dealloc {[super dealloc];}@endUIScrollView把touch事件隔离了,它默认响应的是drag事件。重写UIImageView类,然后往UIScrollView添加CustomizeImageView,并且把self. delegate = self;这样,UIImageView就把touch事件委托给别人处理了,在要处理的类中,实现上述协议即可2023-06-16 04:56:341
