I am deeply influenced by Chairman Mao, the former Chinese communist leader. He has mentioned the famous three paragraph writing: what is the definition of your research, why we do this research, and how we will do. I think it works for all the social, engineering, and science manuscript writing.
What is the definition of your research? Or what is the problem?
You need briefly introduce the background of your research, clearly narrow your research fields, give the conditions, and explain the limitation.
For example, if you study a kind of metal alloy, firstly, you should explain to your readers how the alloy is frequently used. You need specify the ratio of different metals, working conditions of this alloy, and general uses of the alloy.
And what is the problem of current alloy or related research.
Why we do this research?
You should briefly list two or three important points.
For example, for the alloy: Why the problem deserves further research? The challenges and future benefits if we make better alloy. And what can we do?
how we will do?
We can claim we improve some physical properties for this alloy by adding some elements. How we add elements? We can list the experimental procedures, conditions, device information, etc. How we test the new products? We can show how we measure the properties of the new alloy: Melting points, force constants, etc.
Finally, in the conclusion part, we can summarize the results, future influences of new alloy, and what we can do to improve it in the future.
