1. There are two ways to modify the test paper after checking. One is to modify the duplicate checking report after duplicate checking, and the other is to modify it while checking. After checking, if the repetition rate does not meet the requirements, it is very important to revise the paper. To modify a paper, we should not only modify some sentences that are not fluent, but also modify sentences with high repetition rate. If the citation rate is too high, the references of the paper will be rejected.

2. If it is the first time to publish the title of the paper, it is suggested to modify it at the suggestion of friends who edit the journal. They often publish revised papers, which may be very important to our opinions. Of course, it is also good to give us some opinions from the reader's point of view through the reading of friends around us.
