浅述论文摘要和结论的区别

在论文写作中免不了的两个部分就是论文的摘要(abstract)和结论(conclusion)了。一般而言,abstract主要是介绍论文的研究背景,论文的研究方法,稍微涉及一下论文的结论,顺便讲讲论文的益处。

这里选取xuanhe zhao发表在RPL上的论文(Theory of Dielectric Elastomers Capable of Giant Deformation of Actuation)进行举例分析。首先是摘要部分

The deformation of a dielectric induced by voltage is limited by electrical breakdown if the dielectric is stiff, and by electromechanical instability if the dielectric is compliant. The interplay of the two modes of instability is analyzed for a dielectric elastomer, which is compliant at a small stretch, but stiffens steeply.(背景介绍) The theory is illustrated with recent experiments of interpenetrating networks, and with a model of swollen elastomers. (工作内容 )The theory predicts that, for an elastomer with a stress-stretch curve of a desirable form, the voltage can induce giant deformation.(用途)

再看结论部分,

We have shown that giant deformation of actuation is achievable for an elastomer with a stress-stretch curve of a desirable form: the elastomer is compliant at small stretches and then stiffens steeply at modest stretches. (我们做了什么) Such an elastomer either eliminates or survives the snapthrough electromechanical instability, and reaches a stable state before electrical breakdown. (效果)It is hoped that this theory will help in the experimental search for dielectric elastomers capable of giant deformation of actuation.(未来展望)

除了内容上的区别以外,一般abstract上用一般现在时,而conclusion用现在完成时。这个在上面的例子中也有体现。
