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.

纲举目张

什么事情都要个目的没有什么意思，不过，就工作和写作而言，这却非常重要。
我们经常说纲举目张。

凡是要问 目的。

目的就是纲， 没有目的，什么都是白搭。

纲举目张， 目的清楚了， 文笔，排版，华丽才有用武之地。

写文章更是如此，要有一个清楚的目的。所有数据和图标，都是为这个目的服务的。

数据要为结论服务，不要搞反了。

切记切记。
