Technical route generally refers to how you implement your own research methods to achieve research purposes. The technical route should be specific and clear, and can be written item by item. Many people use the way of listing road maps, but it should be noted that some special processes or key methods and technical means should be clearly described.

I think the technical route is best in the form of flow chart. The flow chart can concretize and visualize the research ideas, and the purpose of the experiment is clear at a glance. You can divide the flow chart into three parts: asking questions (research background), analyzing problems (research progress and methods), and solving problems (development strategies and solutions). Then fill in the flow chart with the techniques and means you need in the experiment, risk response, capital budget and so on.
