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; • Describe clearly the objectives of the lab; • Cite the references .
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 Report
Apparatus 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 Report
Results and Discussion
• 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.
