Unit22声音和噪音

我们听到的是所谓的声音。其中运动和声音之间的关系是字，这意味着一动不动，安静的使用建议。

我们可以推断，那么，这声音是与运动相关。运动是能量的一种形式。声音必须产生一些传输通过一些手段，我们的耳朵可以检测其运动的能量来源。

地球上的正常条件下的声音在空气中的速度是334米/秒。如飞机的任何对象，传播比声音慢说是亚音速的速度更快的是超音速。声波是它们传播的媒介，扰乱了正常密度的压缩和扩张的继承。

这种类型的波被称为弹性波，任何给定的声音的音高是由产生的波的频率。一个给定的声音的能量，但是，没有确定的频率，波长，波的速度。声功率是响度，但两者是不一样的。

噪声可以被定义为不受欢迎的声音。然而，这个概念很简单，但它并没有教导我们如何预测的声音将不喜欢。毕竟，一个给定的声音可能是愉快的时候软，但噪音响亮的，可接受的时间很短，但噪音时延长，耐人寻味时的节奏，但噪音时，随机重复，或合理的，当你使它但是当别人的噪音。的所有属性，区分有用和无用的声音，我们一般认为最重要的是响度。

在任何情况下，响度往往是恼人的，因此，他响亮的声音，更可能是被视为噪音。尚未有其他细微之处，使问题复杂化。人们往往联想与电源噪声。

更难以修改的，或许是与社会的认可协会的噪音。就是这样的情况下，过于频繁，大声讲话，一个响亮的摩托车，嘈杂的音乐，特别是玩具枪和鞭炮。

响度是能源，压力或频率，或任何东西可以用物理仪器测量。响度是轰动，如果你想知道一个声音是多么响亮，你必须从听到它的人得到了答案。

但是，它有可能获得有用的信息，从仪器测量一些物理性质，是关系到人类感知的响度的声音。措施健全的仪器称为分贝计，和值的规模被称为分贝（简称DB）的规模。这是设置如下：

（1）规模从零dB，这代表了最柔软的人耳听到的声音。

（2）每个声音强度增加十倍是一个额外的L0 dB.Thus表示，10分贝的声音是微弱的响音激烈L0倍。在一个安静的图书馆的声压级是微弱的响音激烈的约1000倍。因此，库中的声级10 10 10或30分贝。

（3）分贝水平没有直接的添加剂。如果一个沙沙叶是发声的最微弱的声音强度的10倍，两个沙沙作响的树叶激烈，不是100次激烈的20倍，而20分贝响亮。这将需要10沙沙作响的树叶为激烈的10倍，只有这样，分贝至20分贝。

回应声压分贝米，所以人耳，但人耳的响应声音的音质，特别是它的频率，因此它是重要的，我们了解这些非常有趣的属性。

专业英语大作业

一、翻译

1.The breadth and complexity of the environmental problems we face and the scientific, economic and social impediments to their solution emphasize how important it is that environmental scientists and engineers gain an appreciation for the processes and functioning of all environmental compartments — air, soil, water, and energy — and intentionally account for the long-term consequences and sustainability of the actions they propose, whether they be preventative or remedial.我们所面临的环境问题的广度和复杂程度以及对解决这个问题的科学的、经济的、社会的阻碍，都集中到了这样一个重要性：环境科学家与工程师们获得一个对多有环境因素诸如空气、石油、水、能量的流程和功能的判断，有意阐明所提议的行为的长期结果和可持续发展性，是否他们（环境问题）可以预防和补救。

2.As these next-generation technologies are considered, the selection of those for further development and implementation ought to consider a broadened definition of performance to include improved water quality and quantity as well as energy and materials consumption, ecosystem function at the source and sink, life-cycle impacts, and human-health outcomes.这些被认为是下一代技术,它们进一步开发和实现的选择应当考虑改善水质量和数量,以及能源和材料消耗, 在源和水槽,生命周期的影响、人类健康结果的影响的生态系统功能的定义。

3.The next step is to combine the exposure data with so-called exposure–response(or concentration–response)functions(the quantified relationship between health risk and exposure to air pollution)and data for the actual frequency in the given area of, for example, deaths and hospital admissions due to air-pollution-related diseases.考试过程中不得将试卷拆开

下一步是把曝光数据与所谓的曝光–反应（或浓度–响应）功能(健康风险和暴露于空气污染之间的量化关系)和数据的实际频率的特定区域（例如，死亡和因空气污染住院的）相结合

4.Environmental engineers must seek to understand the nature and functioning of large and complex systems in order to protect whole ecosystems, produce new and sustainable technologies, prevent the outbreak of diseases across global scales, and protect the environment from damage resulting from the production of new chemicals.环境工程师必须去理解性质和功能大而复杂的系统,以保护整个生态系统产生新的、可持续的技术,防止疾病的疫情在全球范围传播,保护环境免受新化学物质的破坏。

5.With increased scientific knowledge derived from laboratory studies and environmental monitoring concerning the impacts of the residual constituents found in secondary effluent, it is anticipated that many of the methods now classified as advanced will become conventional within the next 5 to 10 years.随着实验室研究和环境监测有关发现二级污水中残留成分的影响，科学知识在急剧增加，预计,有许多现在列为先进的技术将在未来5至10年成为传统的方法。

6.Nonselective in their mode of attack and able to operate at normal temperature and pressures, hydroxyl radicals are capable of oxidizing almost all reduced materials present without restriction to specific classes or groups of compounds, as compared to other oxidants.相比其他氧化剂，它们能够在非选择性的攻击模式、在正常的温度和压力下,减少几乎所有材料的羟基自由基的氧化能力，然而现在它们没有被划分到具体的类或化合物组，7.International development organizations and human rights groups increasingly insist, however, that environmental problems that deprive vulnerable populations in developing countries of access to shelter, water, or food or that spread diseases, whatever the sources, are security issues.虽然环境问题剥夺了发展中国家的弱势群体获得庇护的权利, 但是, 国际发展组织和人权考试过程中不得将试卷拆开

组织越来越多的坚持水,和食物,或者无论如何产生的传播疾病都是最重要的安全问题。

8.Encouraged by funds appropriated by governments that are motivated by public interest, researchers have turned their research to evaluate damage or potential damage to the “environment”

to humans, other species, or systems that need to be protected.出于公共利益,由政府拨款的鼓励基金支持研究人员用他们的研究来评估伤害或潜在伤害人类的“环境”, 需要保护的其他物种或系统，9.The North China Plain bounded by the Hai, Huai, and Yellow rivers has 33% of China’s population and generates the same national percentage of gross domestic product(GDP)and industrial output, yet only shares 7.7% of the national water resources.Conversely, 21.3% of the country’s water resources are in the southwest, but that region accounts for only 0.7% of the national GDP and industrial output.华北平原有东海,淮河和黄河，拥有中国33%的人口和相同比例的国内生产总值(GDP)和工业产出,但却只有7.7%的国家水资源。相反,我国21.3%的水资源在西南地区,但该地区仅占国家GDP和工业产值的0.7%。

10.The projection is based on a wide range of assumptions about the main forces driving future emissions(such as population growth and technological change)but does not reflect any efforts to control emissions due to concerns about climate change.这个投影是基于驱动未来的碳排放的主要因素(人口增长和技术变革等)一系列假设,但并不能反映由于人们对气候变化的担忧而控制排放的努力。

11.As developing nations industrialize, pollutant concentrations and the numbers of exposed individuals increase;as new chemicals are added to our environment we discover more complex and troubling impacts;as we more carefully monitor ecosystems, we become more alarmed at the threats our activities have on the very fabric of life on Earth.当发展中国家正在工业化时，污染物聚集程度以及暴露在这些化学品影响之下的人数都在考试过程中不得将试卷拆开

逐渐增加；当新的化学物质被应用到我们日常环境中时，我们发现了越来越多的复杂和麻烦的影响；当我们越来越细心仔细的监视着生态系统时，我们也变的对由我们自己日常活动给地球上基本生活结构带来的威胁越来越警觉。

12.Recognition of this interconnectedness has led the African Development Bank and other development organizations to agree that integrating adaptation responses into development planning, which includes improvements in water and sanitation, is an important way to address climate change impacts on the poor.识别的互联性导致了非洲开发银行和其他开发组织同意将适应反应集成到发展规划中,其中包括改善水和卫生设施这一个重要的方法来应对气候变化对穷人的影响

13.Research is ongoing to determine(1)the environmental effects of potential toxic and biologically active substances found in wastewater and(2)how these substances can be removed by both conventional and advanced wastewater-treatment processes.研究确定：(1)废水的环境具有潜在的毒性并可以对生物活性物质产生影响(2)如何利用传统和先进的污水处理工艺发现这些物质

14.For example, a qualitative test may involve the use of a reagent which develops a colour in the presence of the analyte.However, below a certain concentration or detection limit the colour will not be detectable.Thus, the qualitative test is quantitative also in the sense that it can only show that the analyte concentration does not exceed a certain detection limit.例如,定性试验可能涉及使用试剂开发分析物存在的色彩。然而,低于一定浓度或检测极限的颜色不会被检测到。因此,定性试验在某种意义上只能显示浓度不超过一定的检出限的分析物

15.Much of the environment damage caused by developments occurs during the construction phase, and a problem is that construction is usually contracted to a construction company who will not have participated in the EIA process, and over whom the developer may have little control.许多损害环境的事是发生在施工阶段,其中一个问题是,施工单位通常是一个不会参与环境考试过程中不得将试卷拆开

影响评价的公司,而且开发人员也可能会无法控制

16.Nevertheless, the general direction and boundaries of that trajectory can be established through a combination of knowledge of the damaged ecosystem’s pre-existing structure ,composition and functioning, studies on comparable intact ecosystems, information about regional environmental conditions, and analysis of other ecological, cultural and historical reference information.然而,总的方向和边界的轨迹可以通过知识的结合建立受损生态系统的预先存在的结构、组成和功能,比较完整的生态系统,研究区域环境条件、信息和分析其他生态、文化和历史的参考信息等

17.The story of MTBE provides another example of unintended consequences.MTBE was first added to gasoline in the early 1980s to replace the octane enhancer tetraethyllead and to help clean the air by reducing exhaust emissions.Inadvertent leakage from cars and storage tanks, however, has led to MTBE contamination of groundwater, including drinking water sources, in many parts of the United States.MTBE的故事提供了一个意想不到的后果。MTBE在1980年代初首次添加到汽油代替辛烷增强器四乙基铅,并通过减少废气排放帮助清洁空气。然而,却因不慎从汽车和储油罐泄漏,导致了MTBE污染美国许多地区包括饮用水来源的地下水.18.In the simplest circumstances, restoration consists of removing or modifying a specific disturbance, thereby allowing ecological processes to bring about an independent recovery.For example, removing a dam allows the return of an historical flooding regime.在最简单的情况下,去除或修改一个特定的干扰组分,从而为生态过程带来一个独立的复苏。例如,移除一个大坝使洪水可以发生.19.Because of the extensive research into the mechanisms of BNR, the advantages of its use, and the number of BNR systems that have been placed into operation, nutrient removal, for all practical purposes, has become a part of conventional wastewater treatment.考试过程中不得将试卷拆开

第五篇：环境工程专业英语

Environment is the physicsl and biotic habitat which surrounds us;that which we can see.hear, touch, smell, and taste.System.according to Wehster’ s dictionaryD , is defined as “a set or arrangement of things so related or connected as to form a unit or organic whole;as, a solar system, irrigation system, supply system, the world or universe”.•环境：是指我们周围的物理和生物生境，我们可以看到，听到，触到，闻到和感到这些事物。•系统：根据韦氏字典，系统为相关和相联的一组或一系列事情形成一个单元或有机体

Pollution can be defined as an undesirable change in the physical, chemical, or biological

characteristics of the air, water, or land that can harmfully affect the health, survival, or activities of humans or other living organisms.•污染：可以定义为空气、水或土壤的物理化学或生物特性发生恶化以至于对人类或生物有机体的健康、生存或活性造成了危害

When the goal of improving environmental quality is taken to be improving human

well-being.Theword“environment” broadens to include all kinds of social, economic, and cultural aspects.Such broadness is unworkable in many real situations and impractical in a textbook designed for a one-semester course.Our examination of environmental problems is therefore limited by our definition of “environment”.当改善环境质量的目的是用来改善人体健康时，环境这个词的含义就拓宽到包括各种社会、经济和文化方面，但这样的拓宽对许多实际情况不可行的，对为一学期时间设计的课程而言是不现实的。从而我们对环境问题调查时把环境的定义做了限制。

A number of different environmental problems are associated with water, air, or land systems.Many of these problems will apply only within one of these systems, justifying the breakdown into these categories.Such a classification is also useful for easier comprehension of related problems within one system.Moreover, it is sensible because, for managerial and administrative reasons® , such subfields as air pollution, water supply, wastewater diaposal, and solid waste disposal are often dealt with separately by governmental agencies.与水、大气或土地系统来说有一些不同的相关环境问题。而许多问题只是适用于其中的一个系统，正因为此这也说明了上述分类的合理性。如此的分类还有利于更容易对一个系统内相关问题的理解。并且从行政管理方面看也是合理的，因为政府机构经常把环境问题分为空气污染、供水、污水处理和固体废物处置几个方面来处理。

Unfortunately, many important environmental problems are not confined to an air, water, or land system, but involve interactions between systems.但有许多重要的环境问题并不局限于大气、水或土地系统中的某个单一系统，而是包含各系统之间的相互作用。

A current example is the acid rain problem stemming from the emission of sulfur dioxide and nitrogen oxide gases into the atmosphere from the stacks of generating stations®, smelters, and automobile exhausts.一个典型的例子是由于从许多发电站、冶炼厂和汽车排气向大气释放的二氧化硫和氮氧化物造成的酸雨问题。

These gases are then transported by air currents over wide regions, Rainfall “washes them out”, creating acid rain which is harmful to aquatic life, forests, and agricultural crops.Two examples of interaction between systems that cause major environmental disturbances are presented-the buildup of atmospheric carbon dioxide, a global problem.and the acid rain problem.normally of regional nature.这些气体被气流输送到更广的区域，然后经降雨的冲刷后形成了酸雨，这对水生生物、森林和农作物有危害。对各系统间的相互作用造成了较大的环境破坏这里给出了两个例子，一个是全球性问题即大气中二氧化碳的逐渐增加，另一个是酸雨问题，通常是区域性问题。

Many major improvements to our standard of living can be attributed to the application of science and technology.A few examples are noted here.Can you think of others?

• The production of more and better quality food

• The creation of housing as protection from extrcmcs from climates and as living apace

• The building of fast and reliable means of transportation

• The invention of various systems of communication*

*我们生活水平的许多大的改善可以归公于科学技术的应用这里给出几个例子。你能再举出其它的例子? ﹡更多并且质量更好食物的生产﹡快速并可靠的运输方式的创建﹡创造了可以保护我们免受极端气候并作为生活空间的房子﹡多种通信体系的发明

• The invention of machines to replace human or animal power• The supply of safe water and the disposal of wastes

• The elimination of many infectious diseases

﹡可以代替人力和动物的机器的发明﹡安全水的供给与废物的处置﹡传染病的消除

• The elimination of most water-borne diseases in the developed world through improved water technology

• The availability of leisure time through greater productivity, providing the opportunity for cultural and recreational activities

• The protection from the worst effects of natural disasters such as floods, droughts, earthquakes, and volcanic eruptions.﹡在发达国家通过改进水工艺消除了大多数水传染病﹡通过更大的生产力使我们有空闲时间，增加了可以参加提供的文化活动及娱乐活动机会﹡保护我们不受例如洪水、干旱、地震和火山喷发等自然灾害的恶劣影响

With these improvements, however, have come disturbing side effects, such as lost arabic land, disappearing forests, environmental pollution, and new organisms resistant to

controls.尽管有这些改进，但这些改进有困扰我们的副作用，例如可耕地的丧失，森林的消失，环境污染和难以控制的新有机体。Many effects originally considered to be just nuisances are now recognized as potential threata to nature and to humana.这些作用中有许多一开始只被认为是公害，但现在已经被认识到对自然和人类有潜在的威胁。

In an agrarian society, people lived essentially in harmony with mature, raising food, gathering firewood, and making clothing and tools from the land.The wastes from animals and humans were returned to the soil as fertilizer.Few, if any, problems of water, land, or sir pollution occurred.在农业社会，人们基本上与自然和谐相处，在土地中种植粮食，收集木柴，并制作衣服和工具。人类和动物产生的废物以肥料的形式返回土壤中。即使产生了水体、土壤和大气污染，也很少。

The cities of ancient times, particularly those of the Roman Empire® had systems to supply water and to dispose of wastes.The aqueducts supplying the ancient city of Rome(population about 1 million)with safe water from the Cloaca Maxims©, the best known and one of the earliest sewers to be built, are examples of such systems.古代大城市，特别是罗马帝国时的那些城市，有供水和废物处置的体系。该体系一个例子如下：从古罗马的大排泄沟输水管道为有百万人口的罗马城市供应干净的水，这是最著名也是最早建造的排水管。The municipal technology of ancient cities seems to have been forgotten for many centuries by those who built cities throughout Europe.Water supply and waste disposal were neglected, resulting in many outbreaks of dysentery, cholera, typhoid.and other waterborne diseases.许多世纪以来，整个欧洲城市的建筑者们忘记了古代城市的市政工程。供水和废物处置的忽略造成了许多疾病的发作，例如痢疾、霍乱、伤寒和其它水传染疾病。Until the middle of the nineteenth century, it was not realized that improper wastes disposal polluted water supplies with disease-carrying organisms.直到19世纪中叶以前，人们没有意识到废物的不当处置会使给水受到带病有机体的污染。

The industrial revolution in nineteenth-century Britain, Europe, and North Americs aggravated the environmental problems since it brought increased urbanization with the industrialization.英国、欧洲和北美国家在19世纪的工业革命恶化了环境问题，这是因为随着工业化发展城市化加速造成的。Both phenomena, urbanization and industrialization, were and are fundamental causes of water and air pollution which the cities of that time were unable to handle.所有城市化和工业化现象，无论在过去还是现在都是造成在该时代不能处理的水体和大气污染的原因。Rapid advances in technology for the treatment of water and the partisl treatment of wastewster took place in the developed countries over the next few decades.This led to a drsmstic decrease in the incidence of waterborne diseases®.Note that all wastes discharge into the environment, and thus pollute our water, air, and land systems.接下来的几十年里，在发达国家对给水的处理和废水的部分处理方面的技术得到了快速发展。这样就大大减少了水传染病的发生率。我们应注意到排放到环境的所有废物污染了我们的水、大气和土壤系统。1排水工程sewerage engineering，wastewater engineering2排水系统sewer system3排水体制sewerage system4排水设施wastewater facilities5合流制combined system6分流制separate system 7城镇污水urban wastewater8城镇污水系统urban wastewater system9城镇污水污泥urban wastewater sludge10旱流污水dry weather flow，DWF11生活污水domestic sewage;sewage12综合生活污水comprehensive sewage13工业废水industrial wastewater 14入渗地下水infiltrated ground water15总变化系数peaking variation factor16径流系数runoff coefficient17暴雨强度： rainfallintensity18重现期recurrence interval19降雨历时duration of rainfall20汇水面积catchment area 21 地面集水时间inlet time，concentration time22截流倍数
