英语论文写作
论文结论部分(Conclusion)写作特点总结
Conclusion
Conclusion是作者对所研究课题进行的总体性讨论,具有严密的科学性和客观性,反映
本研究课题的价值,同时对以后的研究具有指导意义。
Conclusion与Introduction遥相呼应,因为Introduction部分介绍了本课题的研究目的,
那么Conclusion要告诉读者这些目的是否达到,在研究中做了哪些工作,取得了什么结果,
这些结果说明了什么问题,有何价值和意义,研究过程中存在或发现了哪些问题,原因是什
么,建议如何解决等。
Conclusion的具体内容通常包含以下几个部分:
(1)概括说明本课题的研究内容、结果及其意义与价值。
(2)比较具体地说明本研究证明了什么假设或理论,得出了什么结论,研究结果有何实
用价值,有何创造性成果或见解,解决了什么实际问题,有何应用前景等。
(3)与他人的相关研究进行比较。
(4)本课题的局限性、不足之处,还有哪些尚待解决的问题。
(5)展望前景,或指出进一步研究的方向。
Conclusion通常使用现在时态
Result和Conclusion
本次选取5篇文章,
第一篇,论文中的主要Result已在第2部分和第三部分中叙述,在Conclusion又重新总
结了一下。
第二篇,论文中的主要Result写在Conclusion中。
第三篇,论文中的主要Result写在第3部分(UDIESANDRESULTS)中,
Result和Conclusion是分开的。
第四篇,论文中的主要Result已第4部分的(sandDiscussion)中进行叙述,
Result和Conclusion是分开的。
第五篇,论文中的主要Result已第4部分的(sanddiscussion)中进行叙述,Result
和Conclusion是分开的。

写作特点:
内容:第1句,概括了文章的的主要研究内容。第2句至第8句逐条的列出了文章的得出结
论。
使用了被动语态,Thetwo-dimensionalaerodynamicscharacteristicsoftheNACA63and64
six-digitriesofairfoilsmeasuredintheNASALTPThavebeeninvestigatedhavebeen
investigated.
