The specific structure and format requirements of SCI journals vary from journal to journal, but generally speaking, the format requirements of SCI journals include the following aspects:

-Font, font size and line spacing: Most SCI papers use TimesNewRoman font with font size of 10 and double or single line spacing.

-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).

-Paragraph format: The format of a paragraph includes the first line indentation, font, font size and line spacing (including the first and second paragraphs). 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.

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