Additional Information

Tables and f gures may be presented with captions within the main body of the manuscript; if so,f gures should additionally be uploaded as high resolution fles.

PREPARATION

Use of wordprocessing software

It is important that the fle be sa ved in the nati ve format of the w ordprocessor used.The text should be in single-column format.K eep the layout of the te xt as simple as possible.Most formatting codes will be remo ved and replaced on processing the article.In particular,do not use the w ordprocessor’s options to justify text or to hyphenate words.However,do use bold face,italics,subscripts,superscripts etc.When preparing tables,if you are using a table grid,use only one grid for each individual table and not a grid for each ro w.If no grid is used,use tabs,not spaces,to align columns.The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier:http://www.elsevier.com/guidepublication).Note that source fles of f gures,tables and te xt graphics will be required whether or not you embed your f gures in the text.See also the section on Electronic illustrations.

To avoid unnecessary errors you are strongly advised to use the “spell-check”and “grammar-check” functions of your wordprocessor.

LaTeX

If the LaT eX fle is suitable,proofs will be produced without rek eying the text.The article should preferably be written using Else vier’s document class“elsarticle”,or alternati vely any of the other recognized classes and formats supported in Elsevier’s electronic submissions system,for further information see http://www.elsevier.com/wps/f nd/authorsview.authors/latex-ees-supported.The Else vier “elsarticle” LaT eX style fle package (including detailed instructions for LaT eX preparation) can be obtained from the Quickguide:http://www.elsevier.com/latex.It consists of the fle:elsarticle.cls,complete user documentation for the class fle,bibliographic style fles in various styles,and template fles for a quick start.

Subdivision - numbered sections

Divide your article into clearly def ned and numbered sections.Subsections should be numbered 1.1 (then 1.1.1,1.1.2,...),1.2,etc.(the abstract is not included in section numbering).Use this numbering also for internal crossreferencing:do not just refer to “the text”.Any subsection may be given a brief heading.Each heading should appear on its own separate line.

Introduction

State the objectives of the work and provide an adequate background,avoiding a detailed literature survey or a summary of the results.

Material and methods

Provide suff cient detail to allow the work to be reproduced.Methods already published should be indicated by a reference:only rele vant modif cations should be described.

Theory/calculation

防塵方面防護等級IP65、IP66、IP67是一致的，所不同的是在防止?jié)駳夂退矫嬗胁町悺P65表示向外殼各個方向噴水無有害影響，防護等級IP66則表示向外殼各個方向強烈噴水無有害影響，防護等級IP67為外殼短時間浸入水中無有害影響，而防護等級IP66/67則表示能夠同時滿足噴水或者短時、持續(xù)浸水的要求。

A Theory section should e xtend,not repeat,the background to the article already dealt with in the Introduction and lay the foundation for further w ork.In contrast,a Calculation section represents a practical de velopment from a theoretical basis.

Results

Results should be clear and concise.

Discussion

This should e xplore the signif cance of the results of the w ork,not repeat them.A combined Results and Discussion section is often appropriate.Avoid extensive citations and discussion of published literature.

Conclusions

The main conclusions of the study may be presented in a short Conclusions section,which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Appendices

If there is more than one appendix,the y should be identif ed as A,B,etc.Formulae and equations in appendices should be given separate numbering:Eq.(A.1),Eq.(A.2),etc.; in a subsequent appendix,Eq.(B.1) and so on.Similarly for tables and f gures:TableA.1; Fig.A.1,etc.

Essential title page information

? Title.Concise and informative.Titles are often used in information-retrieval systems.Avoid abbreviations and formulae where possible.

? Author names and affliations.Where the family name may be ambiguous(e.g.,a double name),please indicate this clearly.Present the authors’affliation addresses (where the actual w ork was done) belo w the names.Indicate all affliations with a lo wer-case superscript letter immediately after the author’s name and in front of the appropriate address.Pro vide the full postal address of each affliation,including the country name,and,if available,the e-mail address of each author.

? Corresponding author.Clearly indicate who will handle correspondence at all stages of refereeing and publication,also post-publication.Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.Contact details must be kept up to date by the corresponding author.

? Present/permanent address.If an author has moved since the work described in the article w as done,or w as visiting at the time,a “Present address” (or“Permanent address”) may be indicated as a footnote to that author’s name.The address at which the author actually did the w ork must be retained as the main,affliation address.Superscript Arabic numerals are used for such footnotes.

Abstract

A concise and factual abstract is required.The abstract should state brief y the purpose of the research,the principal results and major conclusions.An abstract is often presented separately from the article,so it must be able to stand alone.For this reason,References should be a voided,but if essential,then cite the author(s) and year(s).Also,non-standard or uncommon abbre viations should be avoided,but if essential the y must be def ned at their f rst mention in the abstract itself.

Keywords

Authors are invited to submit keywords associated with their paper.

Abbreviations

Def ne abbreviations that are not standard in this f eld in a footnote to be placed on the f rst page of the article.Such abbre viations that are una voidable in the abstract must be def ned at their f rst mention there,as well as in the footnote.Ensure consistency of abbreviations throughout the article.

Acknowledgements

Collate acknowledgements in a separate section at the end of the article before the references and do not,therefore,include them on the title page,as a footnote to the title or otherwise.List here those indi viduals who provided help during the research (e.g.,providing language help,writing assistance or proof reading the article,etc.).

Nomenclature and units

Follow internationally accepted rules and con ventions:use the international system of units (SI).If other quantities are mentioned,gi ve their equi valent in SI.Authors wishing to present a table of nomenclature should do so on the second page of their manuscript.

Math formulae

Present simple formulae in the line of normal te xt where possible and use the solidus (/) instead of a horizontal line for small fractional terms,e.g.,X/Y.In principle,variables are to be presented in italics.Po wers of e are often more conveniently denoted by e xp.Number consecuti vely any equations that ha ve to be displayed separately from the text (if referred to explicitly in the text).

Footnotes

Footnotes should be used sparingly.Number them consecuti vely throughout the article,using superscript Arabic numbers.Man y w ordprocessors b uild footnotes into the text,and this feature may be used.Should this not be the case,indicate the position of footnotes in the text and present the footnotes themselves separately at the end of the article.Do not include footnotes in the Reference list.

Tablefootnotes

Indicate each footnote in a table with a superscript lowercase letter.

ARTWORK

Electronic artwork

General points

? Make sure you use uniform lettering and sizing of your original artwork.

? Save text in illustrations as “graphics” or enclose the font.

? Only use the follo wing fonts in your illustrations:Arial,Courier,Times,Symbol.

? Number the illustrations according to their sequence in the text.

? Use a logical naming convention for your artwork fles.

? Provide captions to illustrations separately.

? Produce images near to the desired size of the printed version.

? Submit each f gure as a separate fle.

A detailed guide on electronic artwork is available on our website:http://www.elsevier.com/artworkinstructions

You are urged to visit this site; some excerpts from the detailed information are given here.

Formats

Regardless of the application used,when your electronic artw ork is f nalised,please “save as” or con vert the images to one of the follo wing formats (note the resolution requirements for line dra wings,halftones,and line/halftone combinations given below):

EPS:Vector drawings.Embed the font or save the text as “graphics”.

TIFF:color or grayscale photographs (halftones):al ways use a minimum of 300 dpi.

TIFF:Bitmapped line drawings:use a minimum of 1000 dpi.

TIFF:Combinations bitmapped line/half-tone (color or grayscale):a minimum of 500 dpi is required.

If your electronic artw ork is created in a Microsoft Off ce application (Word,PowerPoint,Excel) then please supply “as is”.

Please do not:

? Supply fles that are optimised for screen use (lik e GIF,BMP,PICT,WPG);the resolution is too low;

? Supply fles that are too low in resolution;

? Submit graphics that are disproportionately large for the content.

Color artwork

Please make sure that artw ork fles are in an acceptable format (TIFF,EPS or MS Off ce fles) and with the correct resolution.If,together with your accepted article,you submit usable color f gures then Elsevier will ensure,at no additional charge,that these f gures will appear in color on the Web (e.g.,ScienceDirect and other sites) re gardless of whether or not these illustrations are reproduced in color in the printed version.

Figure captions

Ensure that each illustration has a caption.Supply captions separately,not attached to the f gure.A caption should comprise a brief title ( not on the f gure itself) and a description of the illustration.K eep text in the illustrations themselves to a minimum but explain all symbols and abbreviations used.

Tables

Number tables consecuti vely in accordance with their appearance in the text.Place footnotes to tables belo w the table body and indicate them with superscript lo wercase letters.Avoid v ertical rules.Be sparing in the use of tables and ensure that the data presented in tables do not duplicate results described elsewhere in the article.

References

Citation in text

Please ensure that every reference cited in the text is also present in the reference list (and vice versa).Any references cited in the abstract must be gi ven in full.Unpublished results and personal communications are not recommended in the reference list,b ut may be mentioned in the te xt.If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either“Unpublished results” or “Personal communication” Citation of a reference as“in press” implies that the item has been accepted for publication.

Web references

As a minimum,the full URL should be gi ven and the date when the reference was last accessed.Any further information,if known (DOI,author names,dates,reference to a source publication,etc.),should also be gi ven.Web references can be listed separately (e.g.,after the reference list) under a dif ferent heading if desired,or can be included in the reference list.

References in a special issue

Please ensure that the words ‘this issue’ are added to an y references in the list(and any citations in the text) to other articles in the same Special Issue.

AFTER ACCEPTANCE

Use of the Digital Object Identifier

The Digital Object Identif er (DOI) may be used to cite and link to electronic documents.The DOI consists of a unique alpha-numeric character string which is assigned to a document by the publisher upon the initial electronic publication.The assigned DOI never changes.Therefore,it is an ideal medium for citing a document,particularly ‘Articles in press’ because the y have not yet received their full bibliographic information.The correct format for citing a DOI is sho wn as follo ws (example taken from a document in the journalPhysics LettersB):

doi:10.1016/j.physletb.2010.09.059

When you use the DOI to create URL hyperlinks to documents on the web,thye are guaranteed never to change.

Proofs

One set of page proofs (as PDF fles) will be sent by e-mail to the corresponding author (if we do not ha ve an e-mail address then paper proofs will be sent by post) or,a link will be pro vided in the e-mail so that authors can do wnload the fles themselv es.Else vier no w pro vides authors with PDF proofs which can be annotated; for this you will need to do wnload Adobe Reader version 7 (or higher) available free from http://get.adobe.com/reader.Instructions on how to annotate PDF fles will accompan y the proofs (also gi ven online).The exact system requirements are given at the Adobe site:

http://www.adobe.com/products/reader/systemreqs.

If you do not wish to use the PDF annotations function,you may list the corrections (including replies to the Query F orm) and return them to Elsevier in an e-mail.Please list your corrections quoting line number.If,for an y reason,this is not possible,then mark the corrections and an y other comments (including replies to the Query F orm) on a printout of your proof and return by f ax,or scan the pages and e-mail,or by post.Please use this proof only for checking the typesetting,editing,completeness and correctness of the text,tables and f gures.Signif cant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor.We will do everything possible to get your article published quickly and accurately – please let us ha ve all your corrections within 48 hours.It is important to ensure that all corrections are sent back to us in one communication:please check carefully before replying,as inclusion of any subsequent corrections cannot be guaranteed.Proofreading is solely your responsibility.Note that Else vier may proceed with the publication of your article if no response is received.
