The role of gratitude in the paper;

The function of gratitude is mainly to show respect for the work of all partners, which is conducive to promoting the formation of a social atmosphere of mutual assistance. The information provided by thanks also helps readers to judge the writing process and value of the paper.

However, the attitude of gratitude should be correct and the wording should be appropriate. In thanking, you can directly write your own name at the end of the article, or you can write your respectful name, such as Professor XXX and Dr XXX. Don't thank the experts who didn't actually review or guide the paper in order to improve the value of the paper. Acknowledgements are usually written at the end of the text and between references. Acknowledgement is generally used for master's and doctoral dissertations with more than tens of thousands of words.
