Graduation thesis can only have one theme (not a few works pieced together), which should be specific to the grassroots level of the problem (that is, the problem can hardly be subdivided into lower-level sub-problems), not the field to which the problem belongs, let alone the subject where the problem lies, in other words, the research topic should not be too big. Because of the wide range of issues involved, it is difficult to study the master's degree thesis thoroughly. Usually, the master's degree thesis should focus on a specific problem in a certain subject field and draw valuable research conclusions.

(2) How to write the title

The topic of graduation thesis should reflect the main content of the thesis work concisely, and should not be general. Because others want to search your paper through the keywords in the title of your paper, it is very important to use accurate language. The title of the paper should be an accurate and specific description of the research object, which generally reflects the research conclusion to some extent. Therefore, the title of our paper should not only tell readers what problems this paper has studied, but also tell readers the conclusions drawn from this study.

(C) the writing of the abstract

The abstract of graduation thesis is a high summary of the research content of the thesis, and others will search the master's degree thesis according to the abstract, so the abstract should include: an explanation of the problem and research purpose, a brief introduction of the methods and research process used, a brief summary of the research conclusion and so on. It should be independent and self-evident, and it should be a complete paper.

(D) Introduction writing

The introduction of a graduation thesis contains the following parts: 1, question; 2. The background and significance of the topic; 3. Literature review; 4. Research methods; 5. The structure of the paper. Ask questions: explain what the problem is, the background and significance of the topic: explain why this topic is chosen for research, that is, explain the contribution of this research to the development of this discipline and the theoretical and practical significance to the national economy and people's livelihood. Literature review: make a comprehensive review of the literature within the scope of this research topic, and at the same time, have "comments", point out the shortcomings of existing research results, and express your own ideas for improvement. Research methods: Explain the scientific research methods used in the paper. Paper structure arrangement: Introduce the writing structure arrangement of this paper. "What has been said in the introduction of the second chapter, the third chapter and the literature review part is not repeated here. (5) Concluding words.

The conclusion is to refine and summarize the main research results and arguments of the paper, which should be accurate, concise, complete and organized, so that people can fully understand the significance, purpose and work content of the paper after reading it. This paper mainly expounds the position, function and significance of his creative work and research achievements in this academic field. At the same time, we should strictly distinguish our own achievements from those of our tutors and others.

(6) Wording requirements

(1) Numbers with a mantissa of 0 "and above 5 digits can be rewritten as numbers in thousands and billions. Under normal circumstances, it is not allowed to take ten, hundreds, thousands, hundreds of thousands, millions, tens of millions, billions, billions, billions, etc. As a unit (except for prefixes of hundreds, thousands and trillions). For example, 1 800 000 can be written as1800 000; 142 500 can be written as 142500, but not as142 500; 5000 words can't be written as 5000 words.

(2) Pure decimals must be located by writing 0 "before decimal point. The "0" at the end of the number of significant digits cannot be omitted and should be written completely. For example, 1.500,1.750,2.000 can't be written 1.5,1.75,2.

(3) The numerical value is modified according to GB 8 170- 1987 "Rules for Numerical Value Modification", and its concise formula is "4-6 enters 5 to see the right, after 5, there are numbers going up, the mantissa is 0 to see the left, and the left number is odd to enter even and discarded". For example, round to the decimal point 1 bit, 12. 149 round to12.1; 12. 169 was changed to12.2; 12. 150 is about 12.2, 12.250 is about 12.2.

(4) The numerical value is multiplied by the length unit, and the unit after each numerical value cannot be omitted. For example, 5 cm×8 cm× 10 cm cannot be written as 5x8×10cm or 5x8×10cm3.

(5) When the units of measurement of a series of values are the same, the unit symbol can only be written after the last 1 bit. For example: 60,80, 100 mol/L. It is unnecessary to write 60 mol/L, 80 mol/L, 100 mol/L. ..

(6) When the scores are arranged by 1 line, the semicolon is diagonal.

(7) There is no uniform requirement to use comma or pause between Arabic numerals juxtaposed in the text, and each editorial department chooses a symbol under the same circumstances to achieve the unity of the whole period.

(8) The words indicating the increase or decrease of figures should be accurate. ① Increase: It can be expressed in multiples or percentages. For example, it is doubled (originally 1, now it is 2); Increase (or improve) 2 times (originally 1, now it is 3); 80% increase (original 1, now1.8); Over 80% (the quota is 100, but actually it is 180). ② Decrease: it cannot be expressed by multiples, but only by percentages or fractions. For example: reduced to the original 80% (original 100, now 80); Reduce (or decrease) by 80% (originally 100, now it is 20); Reduced to the original 1/5 (originally 1, now 0.2); Reduced (or reduced) 1/5 (originally 1, now 0.8) and so on.

(9) When using numbers as marks of grades or groups, attention should be paid to avoid ambiguity or discontinuous numbers. For example: **60 cases, 10 years old, 10/case, > For 9 cases of 20-year-old people, the author should be asked which group the whole10-year-old people belong to; & gt 10 years old and > 20 years old overlap, and the former includes the latter, which should be clearly distinguished.
