Generally speaking, according to the repetition rate requirements of contributing magazines, the repetition rate of English journal papers is as follows: the repetition rate of primary paper topics should not be higher than 30%. The duplicate checking rate of intermediate and provincial papers should be less than 25%. The repetition rate of advanced and national technical papers should not be higher than 20%. The repetition rate of papers in advanced and core journals is about 8% and 15% respectively.

Therefore, English papers can be submitted if the duplicate checking rate is below 30%, but the higher the level, the stricter the duplicate checking rate is. Therefore, it is suggested that the requirement of duplicate checking rate of English periodical papers should be based on the relevant requirements of magazines. Before you formally submit your manuscript, it is necessary to know what the duplicate checking system of papers is currently used by publishing institutions through formal channels. Finally, the repetition rate of papers should be based on the report of the designated paper repetition check system.
