2.2 科技英语的构词
2.2.1 科技英语(SCIENTIFIC ENGLISH)的特点
专业英语词汇特点:专业术语多,合成新词多,前后缀出现频率 高,缩略词经常出现,非限定动词(尤其是分词)使用频繁,词 义单一。 专业英语语法特点:常用形式主语和形式宾语、名词结构和被动 语态使用频繁,复杂长句多,复合句多,每句包含的信息量大。 专业英语的修辞特点:时态运用有限,修辞手法简单,逻辑语法 使用普遍。
2.2.2 科技英语词汇的特点及构词法
化学专业术语构词法: 转化词、复合词、派生词、混生词、缩略词等
化学专业术语构词
1)转化词
n→v: water 水→浇水 yield 产率→生成 a→v: dry 干的→烘干 charge 电荷→充电
2)复合词
又称合成词,是由两个或两个以上的旧词合成一个 新词。
化学专业术语构词
3)派生词derivation
派生词是指利用词的前缀与后缀作为词素构成新词。 派生词的前缀一般要有固定的意义。

GLANCE)·Concentrate first on learning these major peaks and recognizing their presence or absence.1.Is a carbonyl group present? The C=O group gives rise to a strong absorption in the region1820-1660 cm-1(Conjugated ketones appear near 1680 cm-1).The peak is often the strongest in the spectrum and of medium width.2.If C=O is present,check the following types (if it is absent,go to step 3):ACIDS:Is O-H also present?·Broad absorption near 3400-2400 cm-1(usually overlaps C-H) AMIDES:Is N-H also present?·Medium absorption near 3400 cm-1;sometimes a double peak.ESTERS:Is C-O also present?·Strong-intensity absorption near 1300-1000 cm-1.ANHYDRIDES:Two C=O absorption near 1810 and 1760 cm-1.ALDEHYDES:Is aldehyde C-H present?·Two weak absorptions near 2850 and 2750 cm-1.KETONES:The preceding five choices have been eliminated.3.If C=O is absent:Compound may haveALCOHOLS,PHENOLS:Check for O-H.·Broad absorption near 3400-3300 cm-1.·Confirm this by finding C-O near 1300-1000 cm-1.AMINES: :Check for N-H.·Medium absorption(s) near 3400 cm-1ETHERS:Check for C-O near 1300-1000 cm-1(and absence of O-H near 3400 cm-1).4.Double bonds or aromatic rings·C=C is a weak absorption near 1650 cm-1.·Medium-to-strong absorptions in the region 1600-1450 cm-1;these often imply an aromatic ring.·Confirm the double bond or aromatic ring by consulting the C-H region;aromatic and vinyl C-H occur to the left of 3000 cm-1(aliphatic C-H occurs to the right of this value).5. Triple bonds·C≡N is a medium,sharp absorption near 2250 cm-1.·C≡C is a weak, sharp absorption near 2150 cm-1.·Check also for acetylenic ≡C-H near 3300 cm-1.6. Nitro groups·Two strong absorption at 1600-1530 cm-1 and 1390-1300 cm-1.7. Simple Hydrocarbons:V ery few peaks/simple FTIR spectrum showing only –C-H,-CH2,-CH3 vibrations (right side of the 3000 cm-1,bending vibrations appear at 1375 to 1465 cm-1).8.Halogens (F,Cl,Br,I):Fluoride 1400-1000 s; Chloride 785-540 s; Bromide,Iodide<667 s.If none of the above peaks appear:consult a book or research paper for the details of FTIR.OR go to websites www.acros.be; mMMOmolMOMmpMPMRCImRNAMsMS MTBE MW,mol wt m/zNNAD+ NADH NBONBSNCS NICSnmNMO NMP NMR NOE NOESYNRTNuobsdODORDPCCPDCPESPhpivpmPM3PMBPPAppm millimolar (millimoles per liter)molecular orbitalmoles(s);molecular (as in mol wt)methoxymethylmelting pointMøller-Plesset perturbation theorymulti-reference configurationinteractionmessenger ribonucleic acidmethylsulfonyl(mesyl)mass spectrometrymethyl tert-butyl ethermolecular weightmass-to-charge ratio (not m/e)normal (equivalents per liter)nicotinamide adenine dinucleotidereduce NADnature bond orbitalN-bromosuccinimideN-chlorosuccinimidenucleus-independent chemicalshiftnanometer(s)N-methylmorpholine-N-oxideN-methylpyrrolidonenuclear magnetic resonancenuclear Overhauser effectnuclear Overhauser effectspectroscopynatural resonance theorynucleophileobservedoptical densityoptical rotary dispersionpyridinium chlorochromatepyridinium dichromatephotoelectron spectroscopyphenylpivaloylpicometer(s)parametric method 3p-methoxybenzylpoly(phosphoric acid)part(s) per millionPPTSPriPrPTPTCpyqQSARRCMredoxrelR fRHFROESYROMPrRNArtsSARSCFSEMSETS N1S N2S N’SOMOttTTBABTBACTBAFTBSTBHPpyridinium para-toluenesulfonatepropylisopropylperturbation catalysisphase-transfer catalysispyridinequartet (spectral)quantitative structure-activityrelationshipring-closure metathesisreduction-oxidationrelativeretention factor (inchromatography)restricted Hartree-Fockrotating frame Overhauser effectspectroscopyring-opening metathesispolymerizationribosomal ribonucleic acidroom temperaturesinglet (spectrla);second(s)structure-activity relationshipself-consistent fieldscanning electron microscopy;2-trimethylsilyethoxymethylsingle electron transferunimolecular nucleophilicsubstitutionbimolecular nucleophilicsubstitutionnucleophilic substitution withallylic rearrangementsingle-occupied molecular orbitaltriplet (spectral)time;temperature in units ofdegrees Celsius (℃)absolute temperature in units ofkelvins (K)tetrabutylammonium bromidetetrabutylammonium chloridetetrabutylammonium fluoridetert-butyldimethylsilyltert-butyl hydroperoxidTCA TEAB TCNE EDDFT temp TEMPO TfTFA TFAA THF THP TIPS TLC TMAI TMEDA TMS TOFTr tRNAt RTsTS UHF UV VCD visvolv/v trichloroacetic acid etraethylammonium bromide tetracyanoethylenetime-dependent density functional theory temperature2,2,6,6-tetramethylpiperidin-1-oxyl trifluoromethanesulfonyl (triflyl) trifluoroacetic acidtrifluoroacetic anhydride tetrahydrofurantetrahydropyran-2-yltriisopropylsilylthin-layer chromatography tetrabutylammonium iodideN,N,N’,N’-tetramethyl-1,2-ethylenediamine trimethylsilyl;tetramethylsilanetime-of-flighttriphenylmethyl (trityl)transfer ribonucleic acidretention time (in chromatography)para-toluenesulfonyl (tosyl)transition stateunrestricted Hartree-Fockultravioletvibrational circular dichroismvisiblevolumevolume per unit volume。
