As I understand about writing a research project report or master thesis report, it must be complete, self-sufficient. The readers can understand the report/book by reading it thoroughly without the need to consult other sources.
I can think these two ways:
just stated that "the complete mechanism is discussed in ."
But this options make the report not self-sufficient.
paraphrase and cite the original source
This is what I am doing. But I worry that the paraphrase is so similar to the original writing because what I am trying to explain is a physics mechanism which I think it is hard to explain it in another way, especially the structure of the explanation.
I really appreciate any suggestion.
