When writing a paper, its composition mainly consists of title, signature, table of contents, abstract, keywords, introduction, text, conclusion, references and so on. There are strict requirements on the format of the paper. Some of them can't tell the abstract from the introduction. So, today Bian Xiao will talk about the difference between the two, let's take a look!

The difference between abstract and introduction

1. Different meanings: preface, also called introduction, is a short essay written in front of a book or an article, similar to preface or introduction, and the abstract refers to the main points of the excerpt.

2. Different emphases: The preface is the first part of the paper, which is used to introduce the background of the problem, other people's research achievements and shortcomings (brief literature review), thus leading to my own research motivation and the significance of this paper.

It is an overview of the whole paper, which allows readers to quickly understand "what problems this paper has solved and what achievements have been made." It usually includes several parts such as background, purpose, method and result, and each content only needs one or two sentences.

3. Different sources: The preface comes from Cao Jinghua's "Making Honey after Picking Flowers": "In short, these prefaces and postscript can be said to be a key for readers."

From Lu Xun

"My guess is that China's writing has always been inconsistent, the main reason is that it is difficult to write, so we should save some. The oral summary at that time was written by the ancients; The abstract of ancient spoken language is the ancient prose of later generations. "

4. Different functions: Abstract can make readers know the main content of the paper, and whether readers will continue to read other parts of the paper after retrieving the title of the paper can be judged mainly by reading the abstract, which also provides convenience for scientific and technological information personnel and computer retrieval. The introduction mainly puts forward the problems studied in this paper and guides readers to read and understand the full text.

5. Different characteristics: the abstract is independent and self-evident, and has the same main information as the paper, that is, you can get the necessary information without reading the full text. Introduction is a part of the text of the paper and a prelude to the paper. It is not self-evident, so it is impossible to write independently.
