The following points should be paid attention to when writing the abstract of master's degree thesis:
(1) Abstract should be independent and self-explanatory, and have the same main information as the document, that is, you can get the necessary information without reading the full text of the document. Therefore, the abstract is a complete essay that can be quoted. Don't think that "the full text is behind", the summary can be simple and casual.
(2) To objectively and truly reflect the original content, we can appropriately emphasize the innovation and importance of the research, and try to include the main arguments and important details (important arguments or data) of the paper.
(3) Pay attention to the logic of expression and try to express different parts (levels) of the paper with indicative words. If we use "we found ……" to represent the result; Use "analysis based on ..." (we suggest ...) to express discussion, etc.
(4) Strict structure, exact semantics, concise expression and generally no paragraphs are required; Never make empty comments or draw ambiguous conclusions.
(5) Standardized terms, abbreviations, codes, units of measurement and punctuation marks should be adopted.
(6) Don't introduce the content that has become the common sense or popular science knowledge of this subject.
(7) Don't simply repeat the information already expressed in the title of the paper, and don't annotate the title.
(8) Try not to use tables, figures and chemical structures, and do not use chapter numbers, chart numbers, formula numbers and reference contribution numbers listed in this paper.
(9) Don't use abbreviations, abbreviations and codes that are difficult for neighboring professional readers to clearly understand. For example, it is best to write fluid catalytic cracking, study octane number, atmospheric residue, coking gas oil, liquefied petroleum gas, ionic liquid and so on. In the abstract, it is not FCC, RON, AR, CGO, LPG, IL, etc. If abbreviations are really necessary, they must be explained when they first appear in the abstract.
(10) No self-evaluation.
The key to writing is to highlight the great new contribution of the paper and make it sharp. Use incisive sentences to make new discoveries, new theories and new achievements appear in the "prominent position" of the abstract. The so-called new contributions include: new technologies, new theories, new methods, new viewpoints, new laws, correcting predecessors' mistakes, solving disputes, supplementing and developing predecessors' research results, etc. Sharpen new contributions, that is, distinguish the differences between other people's research work and their own new contributions (such as the differences between "ideas", "models" and "applications") and separate them. Don't talk about new contributions, be incisive; You can't be ambiguous, you can't let readers analyze where the author's contribution is "new", but you should specifically point it out to the readers.
