Air pollution is normally defined as air thatcontains one or more chemicals in high enough concentration toharm humans, other animals, vegetation or ？空氣污染通常是指那種包含一種或多種化學(xué)物質(zhì)富集到高濃度并足以傷害人類、其他動(dòng)物、植物或材料的空氣。4）theories,and in particular,mathematical theories,often enable us to bridge the gap between experimentally controlled observations and observations made in the ，尤其是數(shù)學(xué)理論，通常使我們可以彌補(bǔ)（縮?。?shí)驗(yàn)過程觀察的結(jié)果與該領(lǐng)域理論推導(dǎo)的結(jié)果間的差距。四、課文填空：UNIT13的第一部分（Pollution of streams and rivers）PoHution of Streams and RiversWhen sewage is discharged into a freshwater stream，the stream bees pollution。The fish begin to die，but it is not the sewage that is killing them。Rivers in such a condition，which unfortunately can be found near densely polluted areas all over the world，support no fish，are high in bacterial content（usually includingpathogenic organisms），appear muddily bluegreen from choking algae，and，in extreme cases，stink from putrefaction and fermentation。二、大學(xué)生學(xué)好機(jī)械專業(yè)英語的方法必須將機(jī)械專業(yè)知識與英語知識相結(jié)合。而學(xué)生要想擴(kuò)大詞匯量，就必須在閱讀的同時(shí)進(jìn)行識記，并擴(kuò)大閱讀范圍。由于翻譯過程是個(gè)創(chuàng)造性的、從生疏到熟練的過程，只有具備刻苦的精神、嚴(yán)肅認(rèn)真的學(xué)習(xí)態(tài)度和一定的英語水平、專業(yè)水平和漢語表達(dá)水平，才能充分理解原專業(yè)文獻(xiàn)的含義，把握原文的想要表述的實(shí)質(zhì)內(nèi)容，運(yùn)用種種表達(dá)手段和翻譯技巧，用準(zhǔn)確流暢的符合漢語言習(xí)慣的語言生動(dòng)地再現(xiàn)原文。而興趣不是與生俱來的，需要培養(yǎng)。也有學(xué)生反映，專業(yè)英語學(xué)完以后，英語和專業(yè)兩方面都有所鞏固和加強(qiáng)，所以學(xué)生要做的仍舊是樹立信心，保持良好積極的心態(tài)。其實(shí)，隨著社會的發(fā)展，各種工作崗位對人才的要求越來越高，即使作為一名操作工，也有很大可能要面對純英文的說明書、加工圖紙等專業(yè)文獻(xiàn)，更無須說將來擔(dān)任管理和領(lǐng)導(dǎo)崗位對專業(yè)英語的需求了。The river then begins to repurify itself。Now follow the water downstream from “Polutionville.” There processes are going on, all at the same bacteria are feasting on the of this action，the amount of sewage in the water is decreasing，so the BOD is going down。T美國最大的電話電信公司3)CFC=chlorofluoro carbon 含氯氟烴4)Sloppy housekeeping practices such as leaking tanks，valves，or pumps may cause process chemicals to spill requiring cleanup and ，例如儲罐、閥門或泵的泄漏，都會導(dǎo)致工藝過程中化學(xué)品的濺漏而需要采取凈化和處理措施。 and carbohydrates constitute 90 percent of the organic matter in domestic 。 reduction: Any action that reduces the amount of waste exiting a ：減少在于一個(gè)過程中的大量廢物的任何行為。第一篇：環(huán)境專業(yè)英語環(huán)境：environment 環(huán)境工程： environmental engineering 環(huán)境保護(hù)：environmental protection 環(huán)境意識：environmental consciousness/awareness 環(huán)境問題：environmental issue/problem 環(huán)境效應(yīng)：environmental effect 環(huán)境污染：environmental pollution 環(huán)境要素：environmental elements 環(huán)境因子：environmental factors 環(huán)境化學(xué)：environmental chemistry 環(huán)境生態(tài)學(xué)：environmental ecology 環(huán)境質(zhì)量：environmental quality 環(huán)境自凈作用：environmental selfpurification/selfcleansing 水環(huán)境：watershed 水體：water body流域：watershed 水質(zhì)：water quality水資源：water resources 供水：water supply 廢水：waste water水處理：water treatment物理性水質(zhì)指標(biāo)：physical indicate of water quality 水污染物：water pollutant 生物性水質(zhì)指標(biāo)： biological waterquality index 水質(zhì)標(biāo)準(zhǔn)：water quality standard 化學(xué)性水質(zhì)指標(biāo)：chemical waterquality index 物理處理：physical treatment 過濾：screening 生物處理：biological treatment 沉淀：sedimentation 化學(xué)處理：chemical treatment 氣?。篺lotation 物理化學(xué)處理：physicalchemical treatment 蒸發(fā)：evaporation 稀釋：dilution擴(kuò)散：dispersion 吹脫：stripping 好氧處理：aerobic treatment 生物膜法：biomembrane process 厭氧處理：anaerobic treatment 生物濾池：trickling filters 活性污泥法：activated sludge process 生物接觸氧化：biological contact SBR：苯乙烯丁二烯 Styrene Butadiene Rubber UASB（流式厭氧污泥床）：Upflow anaerobic sludge blanket 活性污泥：activated sludge 改進(jìn)型：modification 一級處理：primary treatment 二級處理：secondary treatment 三級處理：tertiary treatment 高級氧化處理：advanced treatment 生活污水：domestic wastewater 生產(chǎn)廢水：industrial wastewater 城市生活污水：municipal wastewater電鍍廢水：metalplating plants 印染廢水：pulp and paper industries wastewater 濁度：turbidity 硬度：hardness 水質(zhì)凈化：water quality purifies 混凝沉淀：coagulate flocculating agent 活性炭吸附：activated carbon adsorption 隔油池：oil separation tank 中和池：neutralization tank調(diào)節(jié)池：adjusting tank 生物反應(yīng)池：biological reactor加藥設(shè)備：physical equipment 沉淀池：sedimentation tank初沉池：primary sedimentation tank 二沉池：secondary sedimentation tank 絮凝劑：flocculant 混凝劑：coagulate flocculant生物降解：biodegradation 生物累積：bioaccumulation飄塵：floating dust 可吸入顆粒物：inhalable particles 能見度：visibility 酸雨：acid rain 一次污染物： primary pollutant 二次污染物：secondary pollutant 氮氧化物：nitrogen oxides 硫氧化物：sulfur oxides 硫化氫：hydrogen sulfide 碳氧化物：carbon oxides硝酸：nitric acid 鹽酸：hydrochloric acid硫酸：sulfuric acid 二氧化硫：sulfur dioxide 除塵工藝：Dust removal吸收：absorption 吸附：adsorption 靜電除塵：electric dust precipitation 重力除塵：gravitational settling臭氧：ozone 光化學(xué)煙霧：photochemical smoke 噴淋（洗滌）：scavenging 土壤：soil 熱污染：temperature change/t
