Formula sorting. The formulas in this paper should be marked with serial numbers and brackets. The serial numbers should be numbered in Arabic numerals, and the numbering method should be unified with tables and legends, such as "(formula 1)". Yes. The serial number "(Formula X)" of the formula is arranged to the right in the middle of the formula layout, and the right margins of all formulas in the full text should be equal (two characters can be indented to the right uniformly).

Formula import. When importing formulas in the paper, we should use an introductory language similar to "as shown in Formula X" instead of "as shown in the following formula". Formula introduction should not be directly used in titles at all levels of the paper, such as "3. XXXXXX (see formula 1 for details) ".

Formula format. When formatting formulas, all mathematical formulas should be edited with the formula editor attached to word software or other software, and text formulas can also be edited in other ways. The formula body should be in the middle of a single line, and there is no need to add a dotted line between the specific formula and "(Formula X)" indicating the serial number.

Formula application. In this paper, whenever a formula is used or a certain numerical connotation of a formula is explained, the usage of "in formula X" should be adopted instead of "see above formula", "in formula X" and "in formula X".
