1. 结论里面可能包括的内容
1. a very brief revisit of the most important findings pointing out how these advance your field from the present state of knowledge （不提供背景信息）
2. a final judgment on the importance and significance those findings in term of their implications and impact, along with possible applications to other areas （强调发现）
3. an indication of the limitations of your study (though the Discussion may be a more appropriate place to do this)（讲不足和限制条件）
4. suggestions for improvements (perhaps in relation to the limitations)
5. recommendations for future work (either for the author, and/or the community)
6. recommendations for policy changes

3. 和摘要的区别
The Abstract is like an advertisement for your paper – it has to attract the reader’s attention. On the other hand, the Conclusions section is designed to remind readers of the most salient points of your paper. However, the Conclusions also have to add value. This added value is typically contained in the recommendations, implications and areas for future research.
4. 如何结束结论部分
1）The first is to show how your work could be applied in another area.
Our findings could be applied quite reliably in other engineering contexts without a significant degradation in performance.Note how the above phrases all make use of could as a hedging device
You might however like to say where they could not be applied for the moment.
2）The second typical ending is to suggest future work.
There is some general agreement that the use of will refers to your own planned work, and that should refers to work that you believe could be addressed by the general community. Thus the following represent the authors’ plans:
S1 One area of future work will be to represent these relationships explicitly …
On the other hand, these examples show possible lines of research for anyone in this particular field:
S2 Future work should benefit greatly by using data on …
3）The third way to end your Conclusions is to make a recommendation.
S3. We suggest that policy makers should give stakeholders a greater role in …
The construction is thus:
to recommend ( suggest, propose ) + that + someone or something + should (optional) + infinitive (without to ) + something
5. 时态的使用
One distinction that many authors make is between what they did during the research ( simple past ) and what they did during the writing process of the manuscript ( present perfect).
We have described a method to extract gold from plastic. We used this method to extract 5 kg of gold from 50 kg of plastic. We found that the optimal conditions for this process were …
