史上最全SCI写作句型模板1——Introduction引言部分应该为读者提供一个关于你的主题的简要概述和进行研究的原因。关于单词数量，引言通常占论文的10-15％。通常建议在完成论文的其他部分后撰写论文的引言部分。这是因为在你看到完整的文章之前，很难弄清楚在论文的引言部分到底要写些什么。你应该对你所选择的主题领域非常有信心，并通过适当的参考文献来支持你的论点。研究论文的引言部分可能包括以下7大类内容，附上常用的写作模板：1.Generalintroduction:·Researchon__hasalongtradition·Fordecades,oneofthemostpopularideasin__literatureistheideathat__·Recenttheoreticaldevelopmentshaverevealedthat__·Acommonstrategyusedtostudy__isto__·Thisresearchconstitutesarelativelynewareawhichhasemergedfrom__·Theseapproacheshavebeeninfluentialinthefieldbecauseof__·Inthepastseveraldecades,__haveplayedanimportantrolein__·Therearegrowingappealsfor__·Thisisthefieldofstudythatdealswith__·Mostofthetheoriesof__arehoweverfocusedonexplaining__·Therearethreemajortheoreticalandconceptualframeworksfor__·Thefieldhasgraduallybroadenedas__·Thisfieldofstudyissometimesreferredas__·Thishasbeenwidelyadoptedinthefieldof__·Thisthesisconsidersthefieldof__asthemainsubjectofitsstudy·Oneofthemajortopicstobeinvestigatedinthisfieldis__·Thisisnowamaturefieldwhichisnowbeingspunoutintocommercialapplications__·Thisfieldismaturing,withawealthofwell-understoodmethodsandalgorithms__·Thisfieldcloselyfollowstheparadigmof__·Thefieldhasmetwithgreatsuccessinmanyproblems__·Thefieldonlyreallytookoffinthelate__asitbecamemoreaccessibleto__·Thisisnotparticularlynewandhasbeenusedformanyyearsinthefieldof__·Thisfieldcloselyfollowstheparadigmof__·Widelyconsideredtobeagoodwayto__·Thishasbeenwidelyadoptedinthefieldof__·Thisismorewidelyusedatthetimeof__·Thisphenomenonhasbeenwidelyobserved·Acommontechniqueisto__·Thisisatechniquecommonin__·Thereareseveralcommonkindsof__2.Problemdefinition:·Thisseemstobeacommonproblemin__·Thisleadstomyriadproblemsin__·Themainproblemisthat__·Thereisafurtherproblemwith__·Oneprimaryproblemwith__isthat__·Themethodsarenotwithouttheirproblemsaswillbediscussedin__·Theforemostproblemsarethefactsthat__·Thismakesupfortheproblemof__·Thisseemstobeacommonproblemin__·Thisisacomplexproblemandtosimplifyitrequires__·Achallengingproblemwhicharisesinthisdomainis__·Theseproblemsaredifficulttohandle__·Thisistypicallyacomplexproblem__·Awell-knownproblemwith__isthatitdoesnottakeintoaccountthe__·Oneoftheproblemsisthatitconsidersonlythe__·Thekeyproblemwiththistechniqueis__·Itisusuallyanill-posedprobleminthecaseof__·Thisproblemiswell-posedanddoesnotrequiretoimpose__·Thisappearsasamorestraightforwardproblemcomparedtothe__·Thisturnsouttobeevenmoreproblematicbecause__·Theproblemwithsuchanimplementationisthat__·Thisposessomeproblemswhencarryingoutthe__·Thisproblemhasattractedmoreattentioninthefieldof__·Thisisabasicchicken-and-eggproblembecause__·Unfortunately,thisapproachresultsinproblemsrelatedto__·Theseconstraintsmaketheproblemdifficultto__·Mostoftheresearchinthisfieldisaimedatsolvingthisproblem.·Thisremainsanopenprobleminthearea.·Thisproblemhasreceivedsubstantialinterest.·Theseexampleshighlighttheproblemthat__·Themainpracticalproblemthatconfrontsusis__3.Gapsinliterature:·Thereisnopreviousresearchusing__approach.·Asfarasweknow,nopreviousresearchhasinvestigated__·Therehasbeenlesspreviousevidencefor__·Otherstudieshavefailedto__·Toourknowledge,nostudyhasyielded__·Nostudytodatehasexamined__·Onlyafewstudieshaveshown__·However,__hasrarelybeenstudieddirectly.·Moreover,fewstudieshavefocussedon__·Inparticularnostudy,toourknowledge,hasconsidered__4.Problemssolution:·Onewaytoovercometheseproblemsisto__·Therearemanyalternativemethodsareavailableforsolvingtheseproblems.·Inordertorectifytheproblemof__·Asolutiontothisproblemisproposedin__·Oneapproachtosolvethisprobleminvolvestheuseof__·Analternativeapproachtotheproblemis__·Thiscanbeappliedtosolvetheseproblems.·Anumberofworkshaveshownthatthisproblemcanbeovercomebyusing__·Alargenumberofalternativeapproacheshavebeendevelopedoverthelastfewdecadesto++·Toovercomethisproblem,inthenextsectionwedemonstrate__·Onewaytoovercomethisproblemisto__·Toovercomethisproblem,someapproacheshavebeenmade__·Onewayofrecoveringfromthisproblemcouldbeto__·Thishasbeenproposedtosurmounttheproblemscausedby__·Adifferentapproachtothetraditionalproblemisgivenin__·Awholerangeofdifferentapproachestotheproblemareavailable.·Thesetechniqueshavepotentialtosolvecontemporaryproblemsin__·Weshouldtailorspecificsolutionstospecificproblems__·Thestandardsolutiontotheproblemisbasedon__·Thesolutionproposedhereaddressesonlytheproblemof__·Therearetechniquesthathavebeendevelopedtosolvethisproblem__·Thisproblemisusuallyovercomeby__·Therehavebeenseveralattemptstosolvetheproblem__·Thereexistmanymethodsfordealingwiththisproblem__·Broadlyspeaking,theproblemcanbeaddressedby__·Oneofthesimplestwaysoftacklingthisproblemis__·Thisproblemhasbeenlargelystudiedandmanyviablesolutionshavebeenfound.·Ingeneral,thisproblemcanbetackledintwodifferentways.·Otherapproacheshavebeenshowntocopewiththeproblemmoreefficiently.·Wewillreviewthemainapproachestosolvethisproblem.·Recently,amoregeneralsolutionhasbeenproposedforthisproblem.·Boththeseworksprovideasolutiontotheproblem.·Recentmethodsfocusonovercomingtheproblemsbyproposingdifferen
