The internal audit of periodicals and magazines shall be audited by magazine editors, and the external audit shall be reviewed by professionals in the industry after passing the examination by magazine editors.

Internal audit is generally a magazine's review of the font format, language expression, logic before and after sentences and repetition rate of papers. Internal audit is based on some problems that are easy to occur.

External audit: mainly depends on whether the quality of the paper reaches the level of periodical submission, which is the audit of professional quality knowledge. External audits take a long time because they sometimes verify the data appearing in the documents. In order to test whether the experimental data and methods in the paper are scientific and whether the conclusions are in line with the development of the industry.

Under normal circumstances, the external audit is reviewed by two professionals. If the external review of the paper is unanimous, it basically means that the paper has passed the review.

On the other hand, if there are great differences among experts in the process of paper review, more reviewers will review the paper again. There is no unified time limit for the specific external audit, so I suggest you wait patiently. If the time is particularly long, you can also rush the manuscript, but you must be careful not to rush the manuscript frequently, otherwise it may be rejected directly by the external auditor.

In the process of publishing a paper, the magazine will review the paper, and after the review, it can be published in the journal smoothly. Under normal circumstances, papers often have three review links, namely, preliminary review, review and final review. However, there are sometimes external reviews of papers.
