今天我们给大家带来“SCI写作高频词、词组系列”引言部分的总结。
SCI论文引言部分的写作难度仅次于文章的讨论部分。引言类似于一个短篇综述, 有严密的逻辑结构和行文规范。一篇SCI论文引言部分的字数一般为500字左右, 大多分为四到五段。一般引言部分分四步走：
第一部分，简要综述该研究在过去和现在的研究现状和背景, 用文献总结概括, 同时要注意引用的文献和数据的准确性和时效性；
第二部分，重点回顾与本课题相关的重要研究, 为本研究做铺垫和导向；
第三部分，俗称“找茬儿”, 要客观公正的评价以往研究中存在的局限性, 引出自己研究的重要性；
第四部分，简单概括本文的研究目的和假说。
SCI论文引言部分写作一般采用现在时, 但前人的工作和发现要用过去时撰写。下面我们就帮大家总结一下SCI写作中引言部分的高频词和词组。
