Preface is usually placed in front of the paper, also known as "introduction", "preface" and "introduction". Used to introduce the research involved in the paper, usually with one or several short paragraphs as the opening remarks. The reader's interest in this paper basically depends on the preface. Then, how to write the preface of the paper and what should be paid attention to? Now let's have a look!

First, how to write the preface of the paper

1. First of all, we should introduce the historical background and theoretical basis of this topic, and whether predecessors or others have different academic views on the research progress and achievements of this topic.

Tell the reader the exact reason why you did this research. Sentences should be concise and clear. If the research project has never been carried out by others, then innovation is obvious. Explain the innovation of this research.

3. However, in most cases, research projects have been carried out by predecessors. At this time, it is necessary to explain the differences and essential differences with other people's research, rather than just repeating the previous work.

Second, what should I pay attention to when writing the preface of the paper?

1. The content of the preface should not be the same as that of the abstract. Please be careful not to use such pleasantries as "a little knowledge", "limited level", "please correct me" and "throwing bricks to attract jade".

2. It is best not to discuss the preface in sections, without illustrations, lists, derivation and proof of formulas, etc. It's best not to be too long, otherwise it will make readers feel boring and not too short, otherwise it will be unclear.

When introducing background knowledge, we must stick to the topic we are studying now, don't digress, or introduce some irrelevant knowledge. At the same time, we should also avoid listing the previous related research results too simply.

As the beginning of the paper, it is very necessary to write a good preface. Therefore, when writing the preface of the paper, you must be considerate and do your best! In addition, we need to remind everyone that after writing the paper, don't forget to use the paper duplicate checking system to detect the repetition rate of the paper!
