*Figures 2 and 3 show pressures and heating rates, normalized with respect to surface conditions.

Some details need to know

Don’t overstate/understate your results.

Overstatement mistake: When only actually shown for one case or small/limited cases.

e.g.

“it shows that x is prevalent in the application.”

“it shows that A is better than B.”

understatement mistake:轻描淡写

fail to consider broader implications of your work.

If your results are less significant, the reviewer and readers will be less interested in your paper.

Numbers: word vs digits

1.When you use numbers from one to ten within a text, write them as words rather than digits.

e.g. for this reason, three samples were measured. (3 samples ✘)

Two hundred samples were examined. (虽然不是1-9，但在句子开头，因此用单词，而非200)

2.Use digits not words when numbers are in association with percentages, abbreviations for measurements, tables and figures etc.(与测量单位、特殊词连写时用数字)

e.g. 20m, 9kg, 9.9%, Table2

In Table 1 and 2, 20 samples with… ✘

In Table 1 and 2, twenty samples with… (减少歧义，让读者易于理解2,20)

Between 4 and 12

5 out of 34

abbreviations and symbols (缩写和符号)

numbers before abbreviations and symbols must be digits.

e.g. the platform weighed 8kg and was 50cm wide.(8kgs ✘,测量单位无负数形式)

the image sequence lasted10min.(ten ✘)

测量单位、缩写都是小写，但字节bytes（e.g. KB, GB），温度temperature(C, F)除外。

The device is 65kg in weight.(65Kg ✘)

Three devices weighed 12kg, 14kg and 15kg.(12,14 and 15kg ✘)

From 12 to 50kg(12kg to 50kg✘)

A few kilograms (e.g. 3kg)…(a few kg ✘)

Singular or plural with numbers

1.whole numbers don’t require an-s to indicate the plural an d no preposition is used between the number and the noun.整数表示不加s，分数加s

e.g.

four thousands of experiments have been conducted so far. ✘)

four thousand experiments have been conducted so far.

One and half hours, three quarters of an hour, four fifths of a liter, nine tenths

2.for reasons of readability, make single digits plural using ‘s, however, for other numbers simply add an s.

e.g. the table contains only 0s and 1s. ✘

the table contains only 0’s and 1’s.一位数字时，数字复数加’s

1990s

a five megabytes memory… ✘

a five-megabyte memory…作为定语，不加复数，加连字符。

Main functional types of writing

Perspective/viewpoint

Defining concepts or objects

Presenting data in classification

Describing process in sequences

Presenting things in time order

Describing certain relationships

Exposing cause-effort connections

Making comparisons and contrasts

Defining concepts

Introduction: some specialized words andexpressions.

Readers may not understand their meanings, they have different meanings in different special subjects.

The author needs to supply the readers with his definition of these term, to make sure that he and his readers are talking and thinking about the same thing.

Definition structure: formal definition.

_____Is a form of/kind of/species of…_____ that/which____.

e.g.: Copper is a kind of substance which is easily shaped, and allows heat and electricity to pass through it.

Naming definition

____that/which____ is known/called/named… as____.

e.g.: The type of electricity that dischargers from a solid material after it has been rubbed with another material is known as static electricity.

Expandingthe definition

It is often necessary to expand the definition description of a concept by adding extra information.

e.g.: by using brackets or dashes.

Tungsten is a metal-used in filament in electric light bulbs-which retains hardness at red heat.

____.Therefore/Consequently/As a result, it is used in____.

e.g.:Aluminum is a metal which is light in weight.Consequently, it is used in the manufacture of aircraft.

Describing processes

introduction: process descriptions often appear in papers.

A process consists of stages moving forward in a logical step-by-step.

e.g.: A Flow Diagram of a partial process of previous information processing.

A process involves linear relationships in a sequence.

Sequencers make the process clear in a sequence.

e.g.: to begin with…next…then…after this…

beginning/first/firstly/to begin with/initially

middle steps/secondly/thirdly/next/then/subsequently/after this/before this/at the same time

end/lastly/finally

Top-to-down design

·Good organization is the key to good writing.

Starting with an outline and working out the details is the normal way of paper writing. It is always better to develop the body paragraphs form an outline instead of doing it directly from the roughly noted points.

Enhancing writing skills

Studying writing styles and effective communication.

Imitating the best native writers in your area: sample papers.

Establishing your own writing databases.

Common words and phrases, sentence patterns, ways of citing references.

Good writing takes times, taking times to enhance writing skills.

writing type: cause-effect relationship

introduction

Exposing cause and effect relation is at the heart of all scientific disciplines.

Cause are harder to identify, or are confused with effects, or researchers do not agree about the causes.

Causes always precede effects (linear relationship).

Expressions for cause-effect relationships

A simple way of showing causal relationship: because + clause (contains verb)

e.g.: The war started because the economic situation was desperate.

Or because of /on account of + phrase

e.g.: The war started because of the desperate economic situation.

Some common words/phrases clearly making the cause and effect relationships:

Verbs: cause/result in/result form

Adverbs: consequently/therefore/hence/thus

Conjunction: because/since/for/so/as

Phrases: be responsible for/be due to/as a result of

Examples of causal relationship descriptions:

*This could cause the downfall of the internet.

*A set of processes of threads is deadlocked since one process is waiting for another one to act.

*This is equivalent to a system setting and consequently saves your effort of setting it in the designer.

Emphasizing on the cause or the effect : be placed first

e.g.: A set of threads is deadlocked since one process is waiting for another one to act.

Different degree of certainty: we need to vary the degree of certainty

e.g.: Because the earth is round, the sun’s energy does not fall evenly over the earth.

Complete:

verbs: is/will/must

Adverbs: certainly/definitely/clearly/undoubtedly/actually

Partial:(strong→less strong)

Verbs: can/could/should/may/might

Adverbs: probably/likely/unlikely/presumably/possibly/perhaps

Impersonal:(i.e.no commitment of self)

It is said that…

X reports that…

There is evidence to suggest that…

Organizing texts: general-specific

A general statement(generalization), starts off a piece of writing/paragraph.

Generalizations introduce many points of details in one statement.

If you read the generalization, you would expect reader to it.

How to Read papers (a three-pass approach)

Presentation skill

To improve communication of key ideas in a presentation.

To provide guidelines for the design preparation and delivery of …

1.Define the desired topic

Specify the subject matter that will be the focus of the presentation. Based on the reason why you will.

2.Define the target audience

Determine type of audience, professionals or general public.

Determine extent of knowledge of your topic.

Estimate size of audience.

Predict audience trigger points.

3.Set presentation time limits.

Set time for presentation components, introduction/main body of presentation/extra presentation aids/questions.

·Predict the number of slides required.

10-15 slides for a 20 minute presentation.

25-30 slides for a 25 minute presentation.

40-45 slides for a 60 minute presentation.

·Basic format guidelines

Backgrounds: use no backgrounds if presentation is black& write.

Use dark backgrounds if presentation is in color.

·Font type and size

Select 2 or 3 fonts for presentation.

All important facts should be 24pt or larger.

Avoid italics.

·Headings format.

Use different color/font for headings.

Heading size is larger than text (e.g. 36pt)

·Content format

最多10-12行，最多3-5个标题，避免长句。

·Animation and video

Avoid complex animation effects.

Design animation to complement presentation.

Speed up or slow down presentation by video.

·Color

Use color to enhance communication of concepts in presentation.

Minimize color used for aesthetic purposes.

Use a maximum of 2-4 colors per slide.

Utilize same color arrangement for heading, subheadings and content.

Step1.

Select background, font type, font size, headings and content format.

Step2.

Develop rough skeleton of presentation including major heading and subheading.

Step3.

Add content to the presentation from information organized.

Step4.

Review presentation and add any missing parts.

Step5.

Add animation and video clips.

Step6.

Review the presentation using animation/video.

Step7.

Perform practice run of presentation and record time.

Step8.

Modify presentation to fit to time limits.

Step9.

Perform practice run in front of sample audience.

Step10.

Modify presentation based on suggestions.

·The dangers of practicing

Practicing too little:

usually presentation will exceed time limit.

Presenter may be forced to refer to notes.

Presenter will likely not be able to answer questions with confidence.

Practicing too much:

Presentation delivery is too mechanical.

Presenter is less spontaneous.

Usually presentation will proceed too quickly.

·Preparing yourself for your presentation

Step1.Print presentation slides(3 to 6slides per page)

Step2.make notes in the printout.

Step3.practice presentation(as discussed)

Step4. verigy that you have supporting material to confidently answer field questions.

·Setting ready for presentation

Step1.reserve presentation media in advance.

Step2.make certain abstract or notice of presentation has been sent with the proper information.

Step3.set up presentation media well before presentation.

·The moments before you present.

Step1.run presentation in your mind using the printed copy of slides with your notes.

Step2.clear your thoughts and retain a sense of calm.

Remember its normal to be nervous, learn to channel the nervous energy to drive you to deliver an outstanding presentation.

·Delivering your presentation

Introduction:

Introduce yourself and your topic clearly.

Clarity of speech:

Make certain that the entire audience can hear you.

Position in front of screen:

Make certain you are facing audience avoid covering the screen.

Monitoring your progress:

Use designated slides to monitor timing during delivery.

Sensing and adapting to audience:

Slowing or speeding presentation based on audience.

Acknowledgements:

Take time to sincerely thank contributors and audience.

Answering questions:

Maintain calm: take your time to think through answers, answer the question only, do not expand on answer unless very confident.

Face questions you can’t answer:

Remain confident and inform the audience that you can’t answer the question at this time, but you are willing to provide the answers later.

Finalizing presentation:

Thanking audience, take your time to thank the audience for participating.

Providing contact information:

Inform audience that they can contact you for further information.

Structure of research papers

1.title

·capitalize the first and last words:

e.g. Procedure After All Questionnaires Are In

·capitalize both elements of a tow-element hyphenated compound word except the second element of a compound numeral:

e.g. EM-Imaging Systems for In-Class Flour Visualization

Evaluation of Twenty-one High-Resolution Graphics Work Stations

·in a hyphenated phrase of three or more words, the first element and other elements that are principal words are capitalized.

e.g. Design of a State-of-the ArtInterference Alleviation System for…

·if a normally lowercase short word is used parallel with a capitalized word of like significance, the short word should be capitalized:

e.g. Electromagnetic Radiation In and Around Airports

·capitalize the infinitive to (note that some authorities recommend lower case for the infinitive)

e.g. In-Loop Deblocking Filter To Improve Subjective Quality of Compressed Video.

In-Loop Deblocking Filter Improving Subjective Quality of Compressed Video.

·Normally lowercase abbreviations should always be left lowercase, particularly abbreviations for units of measure:

e.g. Toughness of 1-ft by 1.5-ftSpecimens

Toughness of 0.5-cm-Thick Specimens

Noise Exposure From 10:00p.m.to 6:00a.m.

But

Multiple Diffractions from the 0.3-Meter(因为不是缩写而是全写)Obstacle

·Headline style capitalization is used for proper nouns

·As a matter of preferred style, the following elements may be capitalized in headline style, applied, e.g. in NASA reports:

Table titles: e.g. Table 4. Test Results for HP-9420.

·Improving titles

Consider replacing or clarifying word with vague meaning such as method, system, facility, use or approach the following example illustrates this point:

·title: An Instrumentation System for Measuring Phase Fluctuation Coefficients

·revision: A Digital Vector Instrumentation System for Measuring Phase Fluctuation Coefficients

·Majority of titles: Noun phrases

A prepositional phrase can be changed to a modifier.

e.g. Analysis of Antenna Array of Waveguides Filled withHydrogen Using Differential Equation Representation

revision: Antenna Array Analysis of Hydrogen-Filled Waveguides Using Differential Equation Representation

·主标题+副标题，更有强调作用；动词→动名词，使意思更清晰。

2.Author/Authors

3.abstract(summary)&keywords(index terms)

Requirement: the abstract should summarize the research paper by briefly conveying the essential information presented in the paper.

Content:

1.the kind of proof (theoretical, experimental, simulations, implementations, etc.) provided to show that the proposed solution is really better than the existing ones.

2.Each component is flexible and brief in length without a fixed order.

3.Avoid equations and math.

摘要时态的问题：

E.g. this paper presents a unique technique for…

Previous research has provided that…

And yet has not confirmed that…

This research investigated how…

We describe a new approach to test…

The experimental results indicate that…

We suggest that this technique could beapplied to …

4.introduction

description of the problem

A brief description of the problem the paper is addressing.

A clear statement why the problem is important (or interesting).

Forming the problem description or statement in a professional way.

Review of related research work

A survey, usually brief compared to the rest part of the paper, only addressing a narrow area of the field.

Describing clearly what has been done before for solving the addressed problem.

Naturally citing or incorporating the relevant reference material into the review.

Clarifying the remaining shortcomings

Stating the shortcomings remaining in the current solutions.

Indicating the troubles, the remaining shortcomings bring about for the solution to the addressed problem.

Outlining the proposed approach & solution.

A brief summary of the proposed method and solution to the addressed problem (and perhaps ever a general description of results).

Describing clearly what is new in your solution (identifying reported new knowledge, the novel aspects of the solution or contributions).

Identifying the significance of the results. (the improvements and impact they suggest).

Summarizing the organization of the paper.

Outline of the rest parts of the paper.

e.g. “the remainder of the paper is organized as follows. In Section 2, we introduce…Section 3 describes… Finally, we describe future work in Section 5.” (Note that section is capitalized)

Vary your expression between “Section” being the subject of the sentence, as in “Section2 discusses…” and “In Section, we discuss…”

Things to avoid

1.Too many motivational materials. Three reasons are enough and they should be described very briefly.

2.Describing unnecessary details.

A detail is unnecessary, if its omission will not harm the reader’s ability to understand the important novel aspects of the result.

3.spelling errors. With the availability of spell checker, there is no reason to have spelling errors red-underlined in a manuscript.

5.theory&solution (material and method)

Objective: describing contributions so that readers can understand them well.

Tips:

Advance previous work? Introduce new concepts?

“An article is finished not when there is nothing more to add, but when there is nothing more that can be taken away.”

A good paper usually addresses exactly one topic

6.experiments &analysis (results & discussion)

Purpose: support your solution.

Presenting the experiment/simulation/measurement results in sufficient details to establish their validity to support the research contributions.

7.conclusion&discussion

Objective: presenting the conclusions drawn from the research and discussing on the relevant issues.
