The writing format of course design instruction
In order to ensure the quality of curriculum design, this specification is formulated.
The design instructions are required to be printed in a unified format, and the layout requirements are as follows:
A4 size
Paper, margins: top
2 cm
, below.
2 cm
, left side
2.5 cm
, right?
2 cm
; Font: Song Ti, small four; Line spacing: fixed value

; Page, face, sheet and edition
Code:
The bottom is centered.
A complete design specification should include the following aspects:
First, the cover (including title, department, student class, design group number, student team name, guidance.
Teachers' names, etc. )
(
See the attachment.

Line), a character is empty between words; Chapter, section and small
Section and its starting page number
(The fonts are all in small four-song style)
Partially indented two characters to the right,
Partial sum post-standard
These questions are indented four characters to the right.
The table of contents should contain entries for the main body and its subsequent parts.
The last one in the catalog.
The item is not numbered.
