The introduction should concisely introduce the research background closely related to the study content → the current research status domestically and internationally (with key references provided) → the reporting situation both domestically and internationally (whether there are relevant reports) → the uniqueness and significance of this study compared to previous research (by exploring..., clarifying..., and providing... for...).

Precautions for Writing the Introduction:

① The introduction should not be written as an indicative abstract that is overly simplistic and fails to address the current status and significance of the research. Its content should neither mirror nor serve as a commentary on the abstract.

② The introduction should be concise and focused. It should not be transformed into a mini-review of a research field, avoiding lengthy narratives of historical origins and problem-posing processes. It should not overly dwell on common background knowledge familiar to peers or found in textbooks. When it is necessary to mention others' research achievements and fundamental principles, they should be cited in the form of references only.

③ When discussing the significance of the research in the introduction, one should be measured in their language, refraining from phrases like 'possessing high academic value,' 'filling a domestic and international gap,' or 'first discovery.' Additionally, avoid using polite expr‍essions such as 'lacking in talent and learning' or 'limited abilities.'

④ For a brief introduction, it is advisable not to divide the content into paragraphs and avoid inserting figures or tables.

⑤ The requirements for terminology in the introduction are the same as those for the abstract.
