Yes.
Because CNKI uses this to select all when checking for plagiarism, and then checks for plagiarism again. This is equivalent to copying and pasting it again by selecting all in Word, and choosing to only display the text when pasting. The elements displayed at this time will be found by CNKI. For example, there are definitely no pictures.
Through verification, we found that if the formula is used in the formula editor that comes with Word, CNKI can recognize it and calculate it into the repetition rate. But if we use a formula editor like Mathtype to insert it, CNKI will not be able to recognize it. It will treat our formula as an image and skip it directly.
So if you use the formula editor that comes with Word, it is best to take a screenshot of the formula after editing it, and then insert it in the format of a picture. Of course, if your computer has a formula editor such as Mathtype installed, it will be easier and you don't need to consider this issue.
