how to write a good scientific paper

A scientific paper is different from all other writings such as a fiction, a novel, an report.
I think there are several points worthy highlighting.
1. A paper must be objective. You can not have intention to support a prior or deny. You are just an observer.
2. A paper must be complete. You should include advantages and disadvantages, or merits and defects.
3. A paper must be precise. That means your description of your observation must be exact and accurate in all its details. Your data must support your conclusions. No conclusion is allowed without efficient data.
