Extended data:

The reasons for irregular writing mainly include three aspects:

1. From the point of view of the responsible editor, there are several reasons for this irregularity: the professional level of the responsible editor is not up to standard, and it is impossible to modify the abstract according to the requirements of the specification; Due to the short publishing cycle and the long time for the responsible editor to modify the abstract, the abstract lacks standardization requirements; The responsible editor has a weak sense of responsibility and ignores the irregular abstract.

2. From the author's point of view, the reasons why the abstract of the paper is not standardized are: the author pays too much attention to the "result" of the publication of the paper, but does not realize the important role of the abstract, so he does not pay enough attention to the writing of the abstract; The author misunderstood the abstract and confused it with the brief introduction of the content.

3. The third situation is special. For various reasons, some academic journals ignore the standardization of abstracts, which makes their own journals present a variety of abstract writing methods, and also makes many contributors follow the "style" of journal abstracts and write irregular abstracts.

Even some senior scholars have to "do as the Romans do" and constantly change the writing format of "Abstract". But in general, there are four main misunderstandings in writing.
