However, when you write a formula with the formula editor that comes with word, HowNet can identify and calculate the content to the duplicate checking rate. If you insert it with a formula editor such as Mathtype, HowNet will recognize the formula as a picture when checking the duplicate, so that it will not check the duplicate and will not affect the duplicate checking rate of the paper.
