Author affiliation can be listed in order of secondary affiliation, basic affiliation, city, postal code and country name. This should take the specific form below.

2.3 Abstract

For the end of epitomizing an article, abstract is a short writing that concisely and accurately tells the article’s important idea without comments and additional explanations. Abstract in Chinese and English is the major content that will be collected by databases at home and abroad, as a result, it exerts a direct influence on whether the article will be collected and how it will be referenced. Contributors shall pay close attention to it. When writing an abstract, contributors should pay attention to following questions:

(1) Abstract should be independent and self-evident. It should carry the same amount of main information as the article, and one can still get the main idea though without reading the whole text.

(2) Following elements should be explored in an abstract: research purpose; approaches; experiment results; conclusion.

(3) Abstract length: better within 300~500 Chinese characters.

(4) Following questions related to language usage need attention: remove wordy parts that are common knowledge in the field, do not simply repeat information already given in article title; faithfully reflect research works done, provide as much quantitative information as possible, no remark on article itself, languages as “…first of its kind”, “…has not been reported yet” etc. are not allowed except that they are necessary; write with a third person style, do not use “this paper”,  “the article”, “the author”, “the penman” etc. for writing Chinese abstract; full forms should be used for abbreviations and acronyms the first time they appear with corresponding short forms. Do not use abbreviations and acronyms for key words unless otherwise commonly used; do not use figures and tables in abstract and usually no paragraph; suitable voice and present tense should be used for abstract in English that may include language as “author”, “this paper” etc.

Abstracts in Chinese and English of the same article should share common content.

2.4 Key words

Key words are standardized words or phrases, which normally are no more than 3~7.Keywords in Chinese and English of the same article should share common content and order.

2.5 CLC number

CLC number is necessary only for Chinese Article. See Chinese Book and Material Classification (the fourth edition). For interdisciplinary article, multiple relevant classification numbers can be used, though main number must be placed at first.

2.6 Introduction

Introduction gives a brief account for research purpose and scope, introduces general situation of work and research already done in related fields, theoretical basis, experimental foundation and research methodology. Plus contributor's intention, expected results as well as their use and importance. It should be concise and comprehensive, and should not become notes for abstract. Basic theories, experimental methods and deduction of fundamental equations in general textbooks should be mentioned no more in introduction. Describe faithfully, prevent boasting of oneself while depreciating others, and avoid promotional language. Define and explain professional glossary or abbreviated expression, no more explanation when they appear in following text, and try to avoid figures and tables in introduction.

2.7 Main text

Each title in the main text should be numbered consecutively and uniformly with Arabic numerals, and written flush. Space of two English characters should be left between the number and the title, as shown in the following form:

                          Article in Chinese:                                     Article in English:

2.10 Biographical notes

Make a brief introduction to the major or all authors at the end of article, including author name(s), gender, date of birth, title/position, research direction, research findings and telephone, E-mail etc.

3 Standard usages

3.1 Terms

Terms approved by China National Committee for Terms in Sciences and Technologies (CNCTST) should be used; technical terms should be used in accordance with relevant standard or regulations; terms known and recognized by public though no standard or regulation for them should be used. Terms coined by the contributor should be explained with notes when they appear for the first time in the article. Terms referring to the same concept or combination of concepts should be consistent in the article. Foreign names can be cited in the original language, no need for translation. Names for general government department, group, school, research institution, enterprise etc. must be cited in full when they appear for the first time in the article.

3.2 Numbers

Usage of numerals should accord with national standard  GB/T 15835－1995 General rules for writing numerals in publications.

Many changes are made for the new national standard, which are explained in short as follows:

 (1) Writing of numerals should accord with GB/T 1.1－1993 Directives for the work of standardization－Unit 1:  Drafting and presentation of standards－Part 1:  General rules for drafting standards.

(2) For numeral multiplication symbol, “×” is used articles in Chinese, “•” is used articles in other languages.

(3) When indicating numerical range of Arabic numerals, “～” should be used. For example: 150 km～200 km,    －100 ℃～180 ℃.

(4) Physical quantity value must be shown with Arabic numerals, and correct official measurement unit should be used.

(5) Use prefixes of SI units properly. Normally, numerical value should be expressed with numbers within 1～1 000, and corresponding prefix should be used to indicate value exceeding the range, e.g. 10 000Pa, should be written into 10 kPa instead of 0.01 MPa.

3.3 Foreign letters

Easily confused letters, symbols and sub- and super-scripts etc. must be typed clearly or written fairly. Times New Roman font should be used for all non-Chinese characters in the printing copy. Strictly distinguish foreign letters language classification, upper & lower case, block & italic, bold & non-bold (e.g. symbols for vector, tensor and matrix are bold and italicized) etc., and mark clearly with pencil when necessary.

3.3.1 Italic

Denoting quantity symbols with italic foreign letters is mainly used in following cases:

(1) Variable symbol, variable affix and function.

(2) Numbers indicated by letter, and letters denoting dot, line, plane, solid & graphics.

(3) Special numerical symbols, e.g. Re (Reynolds number), Fo (Fourier number), Al (Alfrén number) etc.

(4) Parameters deemed as invariable in special cases.　　

3.3.2 Block

Denoting names and their relevant symbols with block foreign letters is mainly used in following cases:

(1) Defined functions (e.g. sin, exp, ln etc.).

(2) Invariable mathematical constants (e.g. e=2.718 281 8…) and defined operators.

(3) Official measurement units, prefixes and dimensional symbols.

(4) Mathematical symbols.

(5) Chemical elements symbols.

(6) Models, symbols and material signs of machines, instruments, equipments and products.

(7) Rigidity symbols.

(8) Foreign abbreviations denoting no quantities.

(9) Latin letters indicating serial numbers.

(10) Subscripts of non-quantity symbols with special meaning added to quantity symbols in order to distinguish from other quantities.

3.4 Quantities, symbols and units

Quantities, symbols and units involved in the article should accord with relevant regulations in national standards as GB 3100－1993  SI units and recommendations for the use of their multiples and of certain other units, GB 3101－1993  Quantities and units－General principles, and GB 3102.1～13-1993 Quantities and units. For those haven’t been regulated in national standards, professional technical manuals as Mechanical Engineering Handbook (the 2nd Edition), Electrical Engineering Handbook (the 2nd Edition) etc. can be referenced. In case neither national standards nor professional technical manuals can be referenced, symbols and units commonly used in the field should be used.

3.5 Punctuations

Punctuation usage should accord with relevant requirements said in national standard GB/T 15834－1995 Use of punctuation marks.

4 Mathematical formulae

Important mathematical formulae should be typed in the middle of a new line, and numbered orderly. Not necessarily number those that the article does not mention again. Numbering should be carried out in the whole article uniformly, not in different parts respectively. Formulae numbers should be written flush at the right end with parenthesized Arabic numerals.

Quantity symbols should be explained one by one with accurate and concise language in the order that they appear, when they appear for the first time in formulae. When necessary, quantity units can be noted in formulae.

Sub- and super-scripts together in one symbol should be avoided in formulae; three sub-or super-scripts in one symbol should be avoided, as well as unnecessary formula deductions.

5 Figures

Figure contents should be closely related to the main text, and dispensable ones should be avoided. There should be corresponding introductions or captions for each figure Lines of figures should be clear, and their sizes should fit journal space with proper layout. In case there are any notes or captions within the figure, they should be highly tangible. Chinese Journal of Mechanical Engineering is not printed in color, wherefore lines in different colors should not be used to denote different meanings, but different line types, e.g. broken line, real line etc.

In case there are more than 2 figures in an article, they should be consecutively numbered with Arabic numerals, e.g. Fig. 1, Fig. 2; if there are multiple sub-figures for a figure, they are numbered with letters as (a), (b) etc., and should have corresponding sub-figure title.

Figure formats are explored briefly with several common figures below.

(1) Coordinate graphs

When there are numerical scales on coordinate axes, scale marks corresponding to certain numerals need to be indicated on relevant axis inwardly. And no numerals, no scale marks. Coordinate axes should be ended at a certain numerical scale point according to graphic range to avoid redundant scale. Arrowheads must be added to coordinate axes when there are no numerical scales.

Beside each axis, physical quantity name, symbol and unit must be given (all the three must be given), for example: Rated current I/A; if it is dimension one quantity (i.e. dimensionless quantity in the past), just physical quantity name and symbol are enough.

Avoid redundant mesh lines within coordinate axes. Beneath is a specific example:

Fig. 6  High order frequency-amplitude features of micro gyroscope

(2) Photographs

When photographs are used, they should be clear. In case they are zoomed out, it should be indicated with “×” plus zooming multiple at the end of photograph title.

Fig. 3  Electronic microscopic picture of naphthenic mineral grease    ×4900

6 Tables

“Three-line tables” are recommended to use, wherein auxiliary lines can be added to explain easily confused contents. Quantity explanation at table head should include physical quantity name, symbol and unit, for example: Rated current I/A; if it is dimension one quantity (i.e. dimensionless quantity in the past), just physical quantity name and unit are enough. In case all data in a table share the same unit, the unit can be indicated at right upper corner of the table, and written flush.

Tables should be numbered with Arabic numerals in the sequence that they appear, e.g. “Table 1”, "Table 2”, and should have corresponding table title. There should be corresponding introductions or captions for each table.

Simple examples are given below.
