Papers need to be integrated and discussed through their own long-term research, even if they learn from other papers and exchange experiences.

The revision of the paper includes the revision of ideas, the revision of cited materials, the revision of structure and the revision of language and punctuation.

Pdf can be copied directly, and caj format can be opened and edited by its caj format reader, but there will be a few errors in copying and pasting directly, so it is better to check it again.
