First, you can't copy.

1. Summarize the opinions again, describe them again in the article with words suitable for your own article language, and make comments.

2. For figures, we should accurately use the environment and conditions of data, indicate the source, and make comments.

3. For some classics, if you want to quote the original text, you must enclose the original text in double quotation marks, indicating that it is the original text of the reference, and indicate the source. Articles should have their own viewpoints and positions, and the viewpoints and positions of each paper should be different. Copying the original texts of other papers directly is a sloppy attitude towards the papers, and it does not deeply consider the position of the cited papers and the context of its own papers.

Second, the reference source

1. Professional papers should cite professional sources as much as possible, and the priority order is as follows: groundbreaking papers with famous disciplines, influential periodical papers, influential conference papers, academic works, general periodical papers, conference papers, agreement versions, legal versions, manual versions, classic textbooks, general guidance books, popular periodicals, newspapers, business periodicals, websites, personal blogs, etc.

2. To find a reference source, find a first-class source. It is the first paper to publish this view. This paper may be cited by other papers, so the cited paper is a second-level paper. Only the primary source is the most authentic expression, and other secondary sources may be mixed with the positions and viewpoints of other authors. Only by finding the first-class source can we show that the author has done a more in-depth study on this issue.

3. Selection of citation sources. Sometimes it is a first-class source, but you can still choose. For example, there are books, papers, websites, databases, reviews and so on. Papers must be cited, and papers are often the most original. If you have research papers, don't use comments, which are often the second source. If you have a paper, you don't need a book unless there are great changes in the book. Papers and books, websites and databases should not be considered.

Third, the order of citing sources.

Sort by order of appearance: the first citation in the article lists the source first. Now the general chinese magazine should follow this standard.

However, the practice of domestic students is often in no order, and there is no order in reading the comment list. This can only be said that the basic writing principles of the paper are not understood, which is not conducive to the duplicate checking of later papers.

Fourth, the source of writing.

General magazines will give their own typesetting methods and order, so everything is based on this principle in order to facilitate readers to find the original text. If the paper is published at an academic conference but not published, it is best to mark the address of the electronic version, as is the internal research report. Databases and manuals used should also be marked with version, year and website for easy searching, and books should be marked with page numbers.

Literature citation should penetrate into different parts of the full text.

Many papers only cite references in the introduction. In fact, all parts of the paper may involve necessary references (if the references only appear in the introduction, it will be unprofessional).

1. Literatures are rarely cited in the title. It is often quoted directly in the title (original title or even author) when modifying the article.

2. The articles cited in the abstract are generally important articles. But the abstract is a text that can be read independently, so it can't be quoted. Literature can be cited in the format of author, publication abbreviation, volume, year and start page. How to do this depends on the release guide.

3. A large number of references usually appear in the introduction. By quoting references, you can achieve the following purposes: explain the source of your problem and why it is important; Point out what you have done and what are the gaps in the problems you face; Point out the method or result you will adopt; Explain what your work will advance, supplement or correct.

4. When introducing the method, you need to cite the literature to explain the source of the method. Even if you give your own methods, quote others' methods appropriately, compare and explain the advantages of your own methods, or quote others' works to test the rationality of your own methods.

5. For the introduction of the results, you need to cite the literature to explain what new or different results you have got. When discussing the results, you need to cite literature to show that your way of thinking is reasonable. If your thesis involves process analysis, then you need to explain whose method you used.

6. Finally, when introducing the conclusion, you can point out what important contributions you have made by comparing the literature.

To sum up, in order to be professional, it is necessary to quote original documents, self-read documents and related documents, respect the original intention of documents, conform to the format requirements and citation norms, logically introduce the job embeddedness of documents into their own content, and quote documents in all parts of the full text.
