You can download the test questions of previous years from this website. This is part of my download, so I can refer to it for the time being. Format specification of papers in the National Mathematical Modeling Competition for College Students: Each team in the undergraduate group chooses one question from A and B, and each team in the specialist group chooses one question from C and D. (For national prizes, the total number of first and second prizes in each group will be distributed according to the proportion of teams participating in each question; However, half of the national first prize places will be evenly distributed to each question in the group, and the other half will be distributed according to the proportion of the teams participating in each question. ) l Paper is printed on one side of white A4 paper; Leave a margin of at least 2.5 cm at the top, bottom, left and right; Tie it from the left. The first page of the document is the commitment letter. See the second page of this specification for the specific content and format. L the second page of the test paper is a special page for numbering, which is used for numbering the test papers before and after the branch and national review. See the third page of this specification for the specific content and format. The title, abstract and key words of the paper are written on the third page of the paper, and the text of the paper starts from the fourth page, not the table of contents. I began to write the page number of my paper from the third page. Page numbers must be located in the middle of the footer of each page and numbered consecutively with Arabic numerals starting from "1". There should be no header in the paper, and there should be no sign that may show the identity of the respondent. L the title of the paper is in bold No.3, and the first-level title is in bold No.4, centered; The second-level and third-level titles are small and bold, and the left end is aligned (not centered). The other Chinese characters in this paper are all Song Zi No.4, and the line spacing is single line spacing. When printing text, try to avoid color printing (except necessary color graphics and charts). L Note: The abstract should be concise and detailed (including keywords), which plays an important role in the evaluation of the whole paper. Please write carefully (note that the length can't exceed one page and it doesn't need to be translated into English). During the national review, the quality of the papers will be preliminarily screened according to their abstracts, overall structure and general situation. L the paper should be clear and concise (the text should be controlled within 20 pages as far as possible, and the number of pages in the appendix is not limited). L In the appendix of the paper version, the name of the software actually used by the participants, the commands and all computer source programs (if any) should be given. At the same time, all source files must be placed in the electronic version of the paper for future reference. The electronic version of papers and programs should be compressed in one file, generally no more than 20MB, and submitted at the same time as the paper version. Citation of other people's achievements or other public information (including information found on the Internet) must be clearly listed in the text citation and references in accordance with the prescribed expression of references. The number of references in the text is indicated by square brackets, such as [1][3] and so on. You must also indicate the page number when quoting books. References are listed in the order cited in the article, in which the description of books is: [No.] author, title, place of publication: publishing house, year of publication. The expressions of periodical papers in references are: [No.] author, title of the paper, name of the magazine, issue number, starting and ending page numbers, and publication year. The expressions of network resources in references are: [No.] author, resource title, website address and access time (year, month and day). L Under the premise of not violating this specification, each division may add other requirements to the paper (such as adding other pages and other information before the first page required by this specification, or adding blank pages at the end of the paper, etc.). ); From the beginning of the letter of commitment to the end of the paper, there shall be no other requirements outside this specification in each competition area (otherwise it will be invalid). The right to interpret this specification belongs to the Organizing Committee of the National Mathematical Modeling Competition for College Students. [Note] Write down the first page of the paper and save it before division review. At the same time, the division review number shall be established on the first page and the second page (the numbering method shall be specified by each division), and the Division Review Record Form can be used for division review (each division decides whether to use this form during review). After the review, the Division will establish a "National Uniform Number" for the papers submitted to the national review on the second page (the numbering method is stipulated by the National Organizing Committee and the format is the same as last year), and then send them to the national review. The second page (numbered page) of the examination paper shall be taken down and kept by the National Organizing Committee before marking, and a "National Marking Number" shall be established on the second page. 20 12 Revised by the Organizing Committee of the National Mathematical Modeling Competition for College Students on August 26th.
