Whether the expression of this description is right or wrong needs to be decided according to the specific situation.

1. Make sure that this expression will not mislead readers or cause misunderstanding. In scientific papers, it is usually suggested to avoid using too subjective or visual language, but to use objective and accurate language to describe research results and discussions.

2. If the visual expression can better convey the research results and the meaning of the discussion, it can be considered, but it needs to be ensured that this expression is consistent with the overall style and language of the paper.

3. If the discussion part of the paper involves the changes of physical quantities such as temperature, it is suggested to express these changes with accurate values and units, rather than just using vague language such as "higher temperature". This can convey the research results more accurately and avoid misunderstandings or unnecessary disputes.
