It should be noted that the price of the dimensional census is relatively high, which may not be very friendly to the first draft. Therefore, before selecting the size inspection, it is necessary to make comprehensive consideration according to your own needs and actual situation, and choose the inspection tool that suits you. For the first draft of the paper, it is suggested that the paper series free duplicate checking software such as paperfree, papertime and paperday can be used for testing, and for the final draft, the duplicate checking system required by the school can be used for testing. Ensure the accuracy and effectiveness of duplicate checking.
