But what the landlord said is chemical reaction, which is different from this. It should refer to the chemical reaction equation. Most people have noticed it, but as an agent, they have not noticed the word "reaction", which is a bit dereliction of duty.
Of course, chemical reactions cannot be written in. This violates Article 25 of the Patent Law and belongs to scientific discovery. This must not be written.
I hope to read carefully before answering questions in the future, and don't mislead others.
