1. Font, font size and line spacing: This is the most basic format. Most SCI papers use TimesNewRoman font, the font size is 10, and the line spacing is double or single. Some journals accept Arial format.

2. Title: The titles of SCI papers are divided into text titles, first, second and third-level titles. Different levels of titles have different fonts and font sizes, and different line spacing (including before and after paragraphs). Pay attention to whether it is bold, whether the font is required, and the case of the title.

3. Paragraph format: The format of a paragraph includes the first line indentation, font, font size and line spacing (including the spacing before and after the paragraph). Some journals need to pay attention to the indentation of the first line of the first paragraph of each part, which is different from other paragraphs.

4. Italics: Individual statistically related characters or Latin scientific names should be expressed in italics.

5. Number of words: Many journals have no requirements for the number of words in articles, but some journals have restrictions on the number of words, and some require no more than 4,500 words or 5,000 words.

6. Column: Most journals use single-column typesetting when submitting, while IEEE journals use double-column typesetting.

7. Other precautions: The layout requirements of each periodical are different, so it is recommended to consult the layout requirements of the periodical in detail for typesetting. First, log in to the journal submission page and find the menu bar, such as author, author information, author guide, etc. , find the submission instructions for the target journals, read them carefully, and then modify them one by one as required. In addition, some journals also provide manuscript templates, which can be typeset according to the templates.
