The number of words in the abstract is about 300. Its elements generally include:
（1）Purpose (The main scope of the premise, purpose and tasks of research, development, investigation, etc.)
（2）Method (Principles, theories, conditions, objects, materials, processes, structures, means, equipment, procedures, etc.)
（3）Result (Experimental results, data, determined relationships, observations, effects, performance, etc.)
（4）Conclusion (Analysis of results, research, comparison, evaluation, application, questions raised, future issues, assumptions, inspiration, recommendations, predictions, etc.)
● Key words
Key words should reflect the subject content of the paper and meet the needs of literature indexing or retrieval. The number of key words ranges from 3 to 8.
Font of Song style (Size 5) is required, and the units involved are suggested to written with international standard symbols. Before and after the decimal point, blank spacing is put between each 3 digits, for example, 1 000.001 002. There is spacing between the quantity and the unit, such as 3 km.
● Constants and variables
Variables are in italics, matrices and vectors are in black italics, and units and constants are used in standardized form.
● Greek letters
For Greek letters that are not in the formula, please use the caret input (in the Word menu, use the insert-symbol-symbol). Do not use the dynamic keyboard to enter.
All formulas are generated using the Mathtypes. Please define the formula size as 5 (10.5 pounds). Please use half-width brackets after the formula number.
Put each figure after the text in which it is cited. All figures could be saved in a file for the convenience of printing. Drawing requirements are as follows.
（1） A figure containing multiple subgraphs is marked with (a), (b), (c), etc., and the total figure name and subgraph name are given; the total figure name and the subgraph name must be placed in the body text.
（2） Please do not use "word picture tool" for drawing. All the figures in the paper can be saved in one file, but each different figure requires a separate picture document, indicating the figure number.
（3） Color: Please use color pictures (the paper version of this journal is color printing).
（4） Scanned pictures: The minimum requirement is a 600-line TIF image; or a source file is provided.
（5） Words in figures: Song style (Size 6) is required. Please keep the independence between words and figure because the words can not cover the main text of figure.
In the form of three line tables (no vertical line or oblique line), they are put after the corresponding text in which they are cited.
