Table of contents

Formal Technical Report

Abstract• State briefly the purpose of the investigation• Describe briefly how the results are obtained• Give all required results in a concise and

quantitative format if possible.• Use words, no tables, figures and equations• Normally no more than 250 words.

Formal Technical Report

Introduction• Include information on the subject of the

investigation and its importance in industry

• Cite the references;

• Describe clearly the objectives of the lab.

Formal Technical Report

Literature review or theory• Provide sufficient theoretical background

to the particular experiments• Develop the equations or models to correlate

your experimental data. Number the equations.

detailed derivation placed in Appendix• Describe how to obtain the model parameters

and predict the particular system• Cite the references

Formal Technical ReportApparatus and Experimental Procedures

• Specify the main apparatuses used make, model and use

• Describe the procedures Highlight important experimental conditions

• Give the names of quality of the materials.

Make sure other people can repeat your work and obtain the same results if they follow your description.

Formal Technical ReportResults and Discussions

• Present the significant experiment results required in the Lab Manual in words and graphs.

• State the data treatment processes and the outcomes.

• Discuss the results of experiments and model simulations or predictions.

• Compare your results with that in literatures if available.

• Logically discuss and lead to conclusions.

Attention• Consistent format• The unit for every parameters in the equations has to

be conformed. • Figures or Tables in the body of text

– Titles of figures, axes, and tables

– Briefly state the experimental conditions

– Experimental data: represented by unique symbol for each group of data in figures

– Modeling curves: different lines with legends– Show model significance when fitting models
