讨论部分的常规写作顺序
1、重新回顾一下论文之前的内容（如Introduction、Results部分），简要地总结一些普遍的或关键的实验结果。尽管你之前已经详细说明的主要的Results，因此类似于Abstract部分那样简单提及几句即可，这么做是为了更自然地过渡到对于你的实验结果的更深层次的解释和讨论。
2、阐述你的研究工作与当前研究领域有哪些关联性，将你的研究成果融入该领域的研究背景中。你在引言部分已经作过文献综述，描绘了研究领域的现状，而此刻你要进一步告诉读者你的研究结果是如何影响、甚至改变了你的研究领域的现状。这种关联性可以是与其它相关文献结果的比较来进行说明，如实验方法的不同、对已有结果进行新的论证、对同一问题得出截然相反的结论、发现一个全新的现象……
3、讨论你的研究工作对该领域产生的贡献程度，提炼出论文可能带来的更深远的影响。研究论文的目的不仅仅是简单地获得和描述结果，而是需要在现有知识背景下如何去理解这些结果，并对其含义进行合理的说明，如研究结果意味着什么？问题和结果之间有什么关系？你的结果与其它文献报导的是否一致？如果你的结果有点出乎意料，务必要尝试解释原因。读者希望知道他们可以从你的论文中获取到哪些可靠的信息。在Results部分你只需要描述清楚你得到了什么实验数据和结果，而Discussion部分的核心作用是与读者探讨它们究竟有哪些意义和作用。
4、重点强调你的研究存在哪些切合实际的应用潜力和前景，同时说明本研究在当前的局限性以及对未来可能的延续性研究的展望。这部分当然也可以放在论文最后的结论部分（Conclusion）再涉及到。在这里提及的局限性并不是指你的研究存在不足，而是为你未来的工作明确一个方向，毕竟一篇短短的研究论文不可能面面俱到。一项好的研究工作应该具有开放的拓展方向和应用前景。 接下来，我们还是通过一段简单的Discussion实例，分别对每一个句子所要表达的内容进行分析，更清晰地分解以上4步模式化的写作方式。
Cognitive-behavioural stress management (CBSM) skills and quality of life in
stress-related disorders
Discussion
1 Prior work has documented the effectiveness of psychosocial intervention in
improving quality of life (QoL) and reducing stress in patients suffering from various disorders; Epstein,18 for example, reports that orthopedic patients participating in a
two-week multimedia intervention programme improved across several QoL indices, including interpersonal conflict and mental health.
1 重新回顾之前的研究部分
2 However, these studies have either been short-term studies or have not focused on patients whose disorder was stress-related. 3 In this study we tested the extent to which an extended three-month stress management programme improved QoL among a group of patients being treated for stress-related skin disorders such as eczema. 4 We found that in virtually all cases, participation in our three-month stress management programme was associated with substantial increases in the skills needed to improve QoL. 5 These findings extend those of Kaliom, confirming that a longer, more intensive period of stress-management training tends to produce more effective skills than when those skills are input over a shorter period via information transfer media such as leaflets and presentations (Kaliom et al., 2003). 6 In addition, the improvements noted in our study were unrelated to age, gender or ethnic background. 7 This study therefore indicates that the benefits gained from
stress-management intervention may address QoL needs across a wide range of patients. 8 Most notably, this is the first study to our knowledge to investigate the effectiveness of extended psychosocial intervention in patients whose disorder is itself thought to be stress-related. 9 Our results provide compelling evidence for long-term involvement with such patients and suggest that this approach appears to be effective in counteracting stress that may exacerbate the disorder. 10 However, some limitations are worth noting.
2 重新回顾引言指出先前的研究方法的不足
3 重新审视本研究所用的方法
4 重新总结概括一次实验结果
5 展示当前工作与本领域的研究关联性和融合性
6 强调结果给某一方面带来的贡献度
7 着重说明这些贡献的意义和含义
8 指出了研究的其中一个成就或贡献是它的创新性
9 重新审视结果的含义与可能的应用前景
10 描述研究的局限性和未来的方向
11 Although our hypotheses were supported statistically, the sample was not
reassessed once the programme was over. 12 Future work should therefore include follow-up work designed to evaluate whether the skills are retained in the long term and also whether they continue to be used to improve QoL. 11 描述研究的局限性和未来的方向
12 明确后续研究工作应当去解决的问题/内容
和上一期对Introduction写作套路的介绍一样，对于Discussion的每个写作模块，下面分别展示了一些更通用的句型、短语或词汇示例。
