【正文】 Homework ? P 39 1,2 。 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. ? 顆粒可提供給非均相大氣化學反應的活性表面,并且可以使大氣中的水蒸氣凝結成泡核體,從而導致明顯的氣候變化和污染效應。 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。 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” “構成”“ 成分”等的表示法 “組成” “構成”“ 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顆粒物都是以揚塵的形式存在,這些揚塵是由高塵的化石燃料燃燒時產(chǎn)生的無機材料和元素碳組成。 Formation and Composition of Innic Particles ? 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反應。θ?:mik] reaction 吸熱反應 ? reversible reaction 可逆反應 ? forward reaction ? reverse reaction ? spontaneous reaction 自發(fā)反應 ? nonspontaneous reaction ?photochemical reaction 反應條件 ?heat 。θ?:mik] reaction 放熱反應 ?endothermic [39。dr?lisis] reaction 水解反應 ?exothermic [39。si: double band 39。 f ] ?H2C=CH2: [39。eitf siks] ?H2SO4: L39。?u] ?C6H6: [39。5H2O: copper( II) sulfate pentahydrate 科技英語中常見分子式及化學反應式讀法 ?(1)讀分子式時,字母部分均按字母名稱讀出。 9. non(a)。 7. hept(a) (sept(a))。 5. penta。 3. tri。 Ion Corresponding acid ——ide hydro ——ic acid ——ite ——ous acid ——ate ——ic acid 例如: Cl (chloride), HCl ( Hydrochloric acid); CN (cyanide) HCN (Hydrocyanic acid). ClO2(chlorite), HClO2 ( Chlorous acid); ClO3(chlorate), HClO3 ( Chloric acid)
