【正文】 ? The position of particulate matter reflects both the elemental position of its source and chemical reactions that may change the position. ? 顆粒物的組成不僅反映了顆粒物來源的元素組成，也表明了可能引起組分改變的化學(xué)反應(yīng)。 ? Among the constituents of inanic particulate matter found in polluted atmosphere are salts, oxides, nitrogen pounds, sulfur pounds, various metals， and radionuclides. ? 在被污染的大氣中發(fā)現(xiàn)的無機(jī)顆粒物的組成包括鹽，氧化物，氮化合物，硫化合物，各種金屬和放射性核素。 1） The earth contains a lot of useful substances. 2） The carbon monoxide content was about 5%. 3） The class consists of 41 students. 4） 41 students constitute the class. Contain, consist of , constitute, include, be made up of, be bined in, pose, form, contain, prise “組成” “構(gòu)成”“ 成分”等的表示法 “組成” “構(gòu)成”“ 成分”等的表示法 Component, position, constitution, constituent, content, formation, ingredient, makeup ? Much of the mineral particulate matter in a polluted atmosphere is in the form of fly ash consisting of inanic material and elemental carbon produced during the bustion of highash fossil fuel. ? 被污染的大氣中含有的大部分無機(jī)顆粒物都是以揚(yáng)塵的形式存在，這些揚(yáng)塵是由高塵的化石燃料燃燒時(shí)產(chǎn)生的無機(jī)材料和元素碳組成。 ? The anic particles of great concern are polycyclic aromatic hydrocarbons(PHA), which consist of condensedring aryl molecules produced by pyrolysis or partial bustion of anic pounds. ? 多環(huán)芳烴是一種備受關(guān)注的有機(jī)顆粒物，它由有機(jī)化合物熱解或部分燃燒產(chǎn)生的稠環(huán)芳基分子組成。 Organic Particles in the Atmosphere ? The most often cited example of a PAH pounds is benzo[a] pyrene, a pound that the body can metabolize to a carcinogenic form: benzo(a) pyrene. ? 苯并芘是最常引用的多環(huán)芳烴，這種化合物能被身體代謝成為致癌物形式的苯并芘。 Organic Particles in the Atmosphere 多環(huán)芳烴 effects of particles ? Particles of to 1um size cause interference phenomena because they are about the same dimensions as the wavelengths of visible light, so their lightscattering properties are especially. ? 1微米粒徑的顆粒物由于和可見光的波長(zhǎng)范圍一致會(huì)產(chǎn)生界面現(xiàn)象，所以他們的光散射特性非常明顯。 effects of particles ? Particles provide active surface on which heterogeneous atmospheric chemical reactions can occur and nucleation bodies for the condensation of atmospheric water vapor，thereby causing significant weather and pollution effects. ? 顆?？商峁┙o非均相大氣化學(xué)反應(yīng)的活性表面，并且可以使大氣中的水蒸氣凝結(jié)成泡核體，從而導(dǎo)致明顯的氣候變化和污染效應(yīng)。 effects of particles ? A strong correlation has been found between increases in the daily mortality rate and acute episodes of air pollution, including those in which particulate pollutions are present in high concentration. ? 研究發(fā)現(xiàn)日常死亡率的增加和突發(fā)性大氣污染，包括那些顆粒污染物以高濃度出現(xiàn)的空氣污染有緊密的相關(guān)性。 Homework ?
