The title of an excellent paper must be very attractive and general, neither too long nor too short. If some details must be placed in the title, in order to avoid redundancy, it can be divided into a main title and a subtitle. The main title is concise, and the details are put in the subtitle. We should summarize the contents, methods and viewpoints of the research topic, as well as the results and conclusions obtained in a condensed form.
The title of a periodical paper is the first important information related to the scope and level of the paper. It is also necessary to consider that compiling secondary documents such as titles and indexes can help select keywords and provide specific practical information for retrieval.
