高三理综化学试题

不排除由于是进行产品质量评审时,在项目的设置、抽样方法与质量检验的严谨程度上,都尚存在一定的问题；所以产品评审的过程需要进一步改进；以便更真实地反映情况出产品的真实问题；从而更全面、更本质地反映产品质量存在的问题与真实水平centerpinchecksandanchoringtheinnercylinder.AccordingtoWhilecouplingalignmentshouldkeepoiloutofcavityandlocatetherotoraxisneckraisedarewithintheprescribedlimits,thereshouldbenogaps,Horn,HornandHorn0.05mmfeelergaugesfitinto.Centercoupling,condenserwaterfillingandwater-filledaccordingtofactoryrequirement.ForcouplingthreesupportedrotorCenter,themouthunderthecouplingbetweenthevalueshouldbeasstipulatedinthemanufacturer,usually0.15~0.25mm.Inthecaseofcouplingconnection,ifpossible,liftingonlyonebearingendofthesupportbearingoftherotor,removethebearing,fittedwithspecialtilesandspecialliftingtools,discrotors,checkthejournalfluttertile,shouldgenerallybelessthan0.10MM.Whenthecouplingsandrotorcomeswhenthereisaconflict,thecouplingCentreshallprevail.6.4.5.2.2shaftlookingfor:...6.4.5.3.Provisionalboltconfirmedthepositioningoftherotorsize,aswellasthecouplingbetweentheadjustmentshimthicknessaccuracy,drawingstomeetthetechnicalrequirements.Plane,cylindricalandcleanthecouplingboltholesshouldbecleanandwithoutburrs,scrapironandgrease-free,relativepositionofthecouplingaccordingtothedrawingrequirementsare.Couplingtopscrews,rounddistanceapart,indicatorstomonitormovementoftheaircraft,itsvalueisallowedtopassthevalueaxismoving,mountedadjustmentpads,notepadsinstallationdirectionguidepincouplingwithprocessendclosed.Thebackwheelsslowlytightened,when2mmorso,withstandardwhitebarswheretwobackwheelboltholemeasurementaboveandbelow,confirmtwobackwheelboltholeconcentricity.Then,thesymmetricalhorizontalmounttwotemporaryboltstightened,attentiontomonitordialindicator,theninstallthesymmetricaltemporarybolts,thistimesitesslowlymovingrotor,inthemeasuredcircumferenceof8equalpartsbackwheelrimrock,eachmeasuringrelativechangesinvalueshouldbelessthan0.02mm.6.4.5.4couplingreamedandpairedboltreamingdiereamer,adjustablereamers,boringmill,inseveralways.6.4.5.4.1Generalrequirementsbeforereamingorboring,高三理综化学试题可能用到的相对原子质量：H-1O-16Ag-108Fe-56C-12S-32Na-23Ca-40一、单项选择题：7．下列说法正确的是（）A．纤维素、蔗糖、果糖和脂肪在一定条件下都可发生水解反应B．CH3CH2OH与氢溴酸不能反应C．甲烷燃烧会生成CO2，因此不属于清洁能源D．我国首艘航母“辽宁舰”上用于舰载机降落的拦阻索是特种钢缆，属于金属材料8．设NA为阿伏加德罗常数的数值，下列说法正确的是（）A．1mol铁与足量氯气反应，转移2NA个电子B．标准状况下，11.2LCCl4含有的分子数约为0.5NAC．常温常压下，32gO2和O3的混合物中含有原子数为2NAD．1L0.1mol·L－1Al2(SO4)3溶液中Al3＋的数目为0.2NA9．下列离子在溶液中能大量共存的一组是（）A．K+、Na+、OH－、AlO2－B．K+、Al3+、Cl-、HCO3-C．H+、NO3－、I－、Cl－D．Fe3+、H+、ClO-、SO32-10．下列实验操作和对应的现象、结论都正确的是（）选项操作现象结论A将饱和FeCl3溶液滴入沸水中溶液变红褐色有Fe(OH)3生成B用燃烧的镁条引燃铝热剂剧烈反应该反应是吸热反应C滴加几滴稀NaOH溶液，将湿润红色石蕊试纸置于试管口试纸不变蓝原溶液中无NH4+D用洁净铂丝蘸取溶液进行焰色反应火焰呈黄色原溶液中有Na+无K+11．下列药品和装置合理且能完成相应实验的是（）A．喷泉实验B．实验室制取并收集氨气A．喷泉实验B．实验室制取并收集氨气不排除由于是进行产品质量评审时,在项目的设置、抽样方法与质量检验的严谨程度上,都尚存在一定的问题；所以产品评审的过程需要进一步改进；以便更真实地反映情况出产品的真实问题；从而更全面、更本质地反映产品质量存在的问题与真实水平centerpinchecksandanchoringtheinnercylinder.AccordingtoWhilecouplingalignmentshouldkeepoiloutofcavityandlocatetherotoraxisneckraisedarewithintheprescribedlimits,thereshouldbenogaps,Horn,HornandHorn0.05mmfeelergaugesfitinto.Centercoupling,condenserwaterfillingandwater-filledaccordingtofactoryrequirement.ForcouplingthreesupportedrotorCenter,themouthunderthecouplingbetweenthevalueshouldbeasstipulatedinthemanufacturer,usually0.15~0.25mm.Inthecaseofcouplingconnection,ifpossible,liftingonlyonebearingendofthesupportbearingoftherotor,removethebearing,fittedwithspecialtilesandspecialliftingtools,discrotors,checkthejournalfluttertile,shouldgenerallybelessthan0.10MM.Whenthecouplingsandrotorcomeswhenthereisaconflict,thecouplingCentreshallprevail.6.4.5.2.2shaftlookingfor:...6.4.5.3.Provisionalboltconfirmedthepositioningoftherotorsize,aswellasthecouplingbetweentheadjustmentshimthicknessaccuracy,drawingstomeetthetechnicalrequirements.Plane,cylindricalandcleanthecouplingboltholesshouldbecleanandwithoutburrs,scrapironandgrease-free,relativepositionofthecouplingaccordingtothedrawingrequirementsare.Couplingtopscrews,rounddistanceapart,indicatorstomonitormovementoftheaircraft,itsvalueisallowedtopassthevalueaxismoving,mountedadjustmentpads,notepadsinstallationdirectionguidepincouplingwithprocessendclosed.Thebackwheelsslowlytightened,when2mmorso,withstandardwhitebarswheretwobackwheelboltholemeasurementaboveandbelow,confirmtwobackwheelboltholeconcentricity.Then,thesymmetricalhorizontalmounttwotemporaryboltstightened,attentiontomonitordialindicator,theninstallthesymmetricaltemporarybolts,thistimesitesslowlymovingrotor,inthemeasuredcircumferenceof8equalpartsbackwheelrimrock,eachmeasuringrelativechangesinvalueshouldbelessthan0.02mm.6.4.5.4couplingreamedandpairedboltreamingdiereamer,adjustablereamers,boringmill,inseveralways.6.4.5.4.1Generalrequirementsbeforereamingorboring,C．制备氢氧化亚铁并观察白色沉淀D．验证苯中是否有碳碳双键12．对于常温下0.1mol·L－1氨水和0.1mol·L－1醋酸，下列说法正确的是A．0.1mol·L－1氨水，溶液的pH=13B．0.1mol·L－1氨水加水稀释，溶液中c(H+)和c(OH－)都减小C．0.1mol·L－1醋酸溶液中：c(H+)＝c(CH3COO－)D．0.1mol·L－1醋酸与0.1mol·L－1NaOH溶液等体积混合所得溶液中：c(Na+)＞c(CH3COO－)＞c(OH－)＞c(H+)22．下列实验现象与对应结论均正确的是选项操作现象结论A常温下将Fe片放入浓H2SO4中生成刺激性气味气体Fe与浓H2SO4反应生成SO2BAl2(SO4)3溶液中滴加过量氨水生成白色胶状物质Al(OH)3不溶于氨水C向某溶液中加入KSCN溶液，再向溶液中加入新制氯水溶
