SCI摘要部分的重要性仅次于SCI题目，绝大多数读者甚至审稿人阅读完题目以后，会先阅读文章的摘要部分，当摘要部分引起读者兴趣的时候，读者才会选择进一步地阅读其它部分。
别看摘要部分才短短的200-300字，但却麻雀虽小，五脏俱全，基本上是整篇文章的等比例的微缩版。摘要的写作难度并不大，有“起承转合”固定的写作模式，如果再结合我们所总结的几大板块以及相应部分的高频词汇词组，我想人人都可以成为摘要高手！
纵观各类期刊，摘要基本可以分为五大部分的内容：
| 第一部分： | Background |
| 第二部分： | Purpose/Objective |
| 第三部分： | Methods (and Materials) |
| 第四部分： | Results/Findings |
| 第五部分： | Conclusions/Interpretation |
很多期刊不会明确要求一定要按固定的模式写，就是写一段话，由作者决定安排这五部分的内容。但也有很多期刊，第一，四，和五部分是必选项，而对于第二部分和第三部分不同的杂志有各自不同的要求。
大家在投稿的时候要注意期刊对这五部分是怎么要求的，而且要看清要求的背景、研究目的、材料方法、结果、结论这几项英文单词的格式问题：有的只有首字母大写，有的要全部字母大写；有的要求这几个字母后面跟空格，有的跟冒号，有的要换行。
下面两个图是两个不同杂志的模板，大家可以看一下它们是怎样的要求。
