According to academic norms and format requirements, handwritten paper abstracts are written in a top-down way. Write the title in the center of the paper to ensure that the title is obvious. Start a new line and then start writing a summary. At the beginning of the first line, mark it with a colon, and then write a concrete summary. It is helpful to make the whole paper structure clear and easy to read, and accurately convey the core information of research work to readers.
