1. This article "What to replace?

Articles, papers, researchers, theoretical assumptions, research findings, investigation proofs, results display, etc.

Since it is a scientific paper, it must have a certain theoretical basis. Even if no specific form is developed, at least the theoretical reasoning must be correct, so "this paper" focuses on the argumentation process and argumentation principle, which makes people believe that your research results are correct and reasonable. But it can't prove what truth is by itself unless you have a lot of detailed survey data.

2. Which words in the paper belong to spoken words and which written words have been replaced?

The sentence "our list is as follows" is obviously not smooth. The main problem is "we". Just delete "we" or replace "we" with a list name, for example, "All names are listed below".

There is nothing wrong with the sentence "We can draw a conclusion from the above experimental results", but it is a bit colloquial. More is to write adjustment "xxxxx conclusion can be drawn from the above experimental results". In fact, the easiest way is to ask someone to help read and correct the whole paper.

Proper practice, writing more articles, simple and in-depth sentence patterns, and correct and hierarchical use of punctuation marks can be practiced into written language for a long time.
