Whether the acknowledgement part of the paper will calculate the duplicate checking rate depends on the requirements of specific schools or duplicate checking systems. Some schools or duplicate checking systems may require that the receipt part be included in the duplicate checking scope, while others may not. Usually, the duplicate checking system mainly aims at the main parts of the paper, such as abstract, introduction, text and so on. However, if some acknowledgements are duplicated with published papers or public information on the Internet, they may be regarded as plagiarism. Therefore, it is suggested that the author write the thank-you part according to the specific requirements of his school or institution, and pay attention to avoiding plagiarism.
