How to label the references of undergraduate graduation thesis can be analyzed from three aspects: labeling methods, labeling requirements and labeling formats.

There are two ways to mark references: one is to mark the text with superscript numbers, and the other is to mark the text with the author's year system. Different schools or disciplines may have different requirements, so you need to choose the appropriate labeling method according to the norms of your school or discipline.

If marked with superscript numbers, the superscript numbers are used to indicate the serial numbers quoted in the text, such as [1][2] and so on. At the end of the paper, the detailed information of all references is listed in citation order.

If it is marked by the author's year system, then the author and the cited year are indicated in brackets, such as (Zhang San, 2020) (Li Si et al. , 20 19), the detailed information of all references is listed at the end of the article in alphabetical order.

2. Label requirements

First of all, the references cited in this paper should correspond to those listed at the end of the paper, and should not be omitted or redundant. Secondly, the format of references should be unified and standardized, and cannot be changed or omitted at will. At the same time, we should avoid over-quoting or directly quoting other people's content, try to paraphrase or summarize it in our own words, and mark the original text with quotation marks when necessary.

3. Tag format

If marked with superscript numbers, the information of references includes author, title, place of publication, publisher, year of publication, page number, etc. Different types of documents have different formats, such as monographs [M], journal papers [J], dissertations [D] and so on.

If it is marked by the author's year, the information of the reference includes the author, year, title, publishing place, publishing house, page number, etc. Different types of documents have different formats. For example: Zhang San. (2020). On the development and innovation of vocational education. Beijing: Education Press.
