First of all, topic selection is very important in the writing of academic papers. This is because only by studying meaningful topics can we get good results and benefit the scientific cause and real life; And a meaningless research, no matter how well researched and beautifully written, has no scientific value. Professor Qian Xuesen said: "The research topic should be closely integrated with the needs of the country. ..... In terms of research methods, we should avoid going into a dead end and engaging in complex philosophy. At present, in the social sciences, some people make a big fuss about a sentence of the ancients, repeatedly textual research, and write a big paper. I don't think this is interesting. " Therefore, we should choose subjects with scientific value for research and writing. So, what principle should we choose the topic according to?

(1) is scientific. It should include: problems that need to be solved urgently; New discoveries and creations in science; Fill in the gaps or gaps in the discipline; Correct the popular saying; Supplement to previous theories; Wait a minute.

(2) Conducive to development. Refers to: have a strong interest; Able to play professional expertise; Easy before difficult, moderate size; Have some information; Can get the guidance of the tutor; Can be completed in a certain time; Limit the topic.

Matters needing attention

1, the abstract should exclude the content that has become common sense in this subject field; Never write what should appear in the introduction into the abstract; Generally don't interpret and comment on the content of the paper (especially self-evaluation).

2. Don't simply repeat the information already in the title. For example, if the title of an article is "Study on Rhizome Formation in Vitro Culture of Several Orchids from China", then don't write at the beginning of the abstract: "For.

3. Rigorous structure, concise expression and exact semantics. What to write first, then what to write, should be arranged in logical order. Sentences should be coherent and echo each other. Use long sentences with caution and keep them as simple as possible. Every sentence should be clear, and there should be no vague, general or vague words, but the abstract is a complete essay after all, and telegraph writing is not enough. The abstract is not segmented.

4. Use the third person. It is suggested that the description methods such as "research …", "report …" and "investigation …" should be used to indicate the nature and theme of the literature at one time, instead of "this article" and "author" as subjects.

5. Use standard terms, and do not disclose symbols and terms. If there are new terms or no suitable Chinese terms, you can indicate the original text in brackets or after translation.

6. In addition to being really inflexible, mathematical formulas and chemical structural formulas are generally not used, and there are no illustrations and tables.

7. There is no need to quote unless the document confirms or denies the published works of others.

8. Abbreviations, abbreviations and codes must be explained when they first appear, except those that can be clearly understood by readers of adjacent majors. Other matters that should be paid attention to when writing scientific papers, such as adopting legal units of measurement, using language and punctuation correctly, are also applicable to the preparation of abstracts. The main problems in the compilation are: incomplete elements, or lack of purpose, or lack of methods; Citation is not independent and self-evident; Improper simplification.
