讨论部分是SCI论文写作难度最大，也是最能体现文章深度和创新性的部分。一般分四大部分进行描述：

第一部分，精要概括文章的研究背景以及本课题的主要研究目的、实验手段以及发现的结果。

第二部分，深入讨论结果部分中的重要研究发现。通过比对引用前人的研究结果，讨论自己的研究结果。讨论的角度可以从课题设计、分析方法、实验技术改进等方面进行切入。如果课题中的研究结果是验证前人的研究发现，就不需要深入讨论, 要把讨论重点放在和前人研究结果不一样，或者前人没有发现过的独特的有创新性的结果。

第三部分，指明自己研究的不足之处。可以从课题设计、实验手段、分析方法、是否需要进一步实验验证入手。因为任何课题都不会是完美的，能把自己的不足主动列出来并说明对本课题“有限”的影响，会让审稿人觉得作者对自己课题是很了解的，有的时候也就不会让作者再补充相关实验。

第四部分，再次总结文章的实验发现和研究意义、贡献以及下一步的研究方向。有的期刊要求把这部分独立出来称为“Conclusion”。

讨论部分的时态一般为过去时，在介绍前人研究时，则一般采用过去时或现在完成时。
