Due to the differences in language structure and expression between Chinese and English, some mistakes and ambiguities will inevitably appear in translation. If the translation quality is not high, it will easily lead to the deviation and confusion of the original intention, and even lead to the confusion of the structure and logic of the paper. These problems may increase the difficulty of paper weight reduction, but they do not affect the accuracy of paper weight checking tools. Only on the basis of high translation quality can we better pass the duplicate checking test and get qualified papers.
