SCI写作 ｜ 摘要写作结构+模板
摘要一般是论文的最后一个写作环节，也是笔者认为最难写的部分，需要精雕细琢来突出最想让审稿人和读者阅读的闪光点，其重要性仅次于题目。好的摘要可以增加论文被录用和被引用的概率。
#01 摘要主要包含五个部分
别看摘要才短短200-300字，但它基本上是整篇论文等比例的微缩版。SCI论文通常采用结构化的摘要，其基本组成部分是：
#02 摘要写作的一般注意事项
摘要是论文主体的浓缩，所以一般都是在完成论文主体的各个部分后再写的，提炼压缩各个部分成1-2句话，并有逻辑地连接起来即可。
摘要应该是独立和简洁的，需要清晰的逻辑思路，旨在描述您的工作，但不会深入细节。所以摘要里不要充斥着大量数字，但是要有必要的数据。
大多数期刊要求摘要避免使用缩写词。不用引文，一般不出现书写公式、化学结构式、插图和表格。
切记勿将正文的部分直接截取过来作为摘要，摘要出现字句也不要原封不动的照搬到正文里。
摘要尽量用短语，用动词的主动语态，同时最好用第三人称。描述研究工作一般用过去时态，但在说明结论时，应用现在时态。
简单点说一个好的研究就是提出问题，解决问题。所以研究问题和结果为摘要的重点部分。重要的结果在摘要就体现出来，给读者一目了然的信息，不要故留悬念。
最后阐述本文的重要意义时，记得对之前描述的“现有研究不足”和“研究问题”给予回应。
摘要中常见的问题有：摘要过长、长句过多、目的或研究问题不明确、数值和数据统计结果过多、总结没有基于结果，太过空乏。
