They must be based on the existence of other structural units (referring to upper structural units). Generally speaking, volume, as the highest level structural unit, is only applicable to some huge normative documents with complex structural levels, such as foreign civil codes and comprehensive codes. There are no normative documents by volume in China, which are omitted here.
As for the compilation, it is second only to the volume, and only applies to relatively large codes with more provisions such as criminal law, criminal procedure law and civil procedure law. For standardization construction, it is unlikely that the internal management norms formulated need to be compiled as the structural unit.
Extended data:
As the structural unit of normative documents, it mainly includes: volume, compilation, chapter, section, article, paragraph, item and item, which is very clear to everyone. Among them, volume, compilation, chapter and section are the structural units of the title, and articles, paragraphs, items and items are the structural units of the article.
On the other hand, volumes, departments, sheets and strips are independent structural units, which are not based on the existence of other structural units (mainly upper structural units), while sections, paragraphs, items and items are subordinate structural units and must be based on the existence of other structural units (upper structural units).
After the paper is published, the abstract can be directly used by abstract magazines or various databases without modification or slight modification, so that readers can know the main contents of the paper as soon as possible to supplement the deficiency of the title, thus avoiding misunderstandings, deficiencies and even mistakes that may occur when others compile the abstract. Therefore, the quality of abstracts directly affects the retrieval rate and citation frequency of papers.
