What are the references, appendices and introduction of the paper? There is also a table of contents, the first is the abstract? (Thanks to the capable people for their help)

The abstract comes first, then the table of contents, and then the text.

The introduction mainly introduces the background, significance, literature review, research methods and so on.

You can add some pictures to the text to increase the visibility.

If there are too many tables and data, put them in the appendix.

Paper references, pay special attention to the format, this online should be able to find a lot.

I hope I can help you!
