六月底我完成了 LT21 铝合金试样原位 CT 表征的分析工作。对退役反应堆核材料结构性能的分析有助于了解辐射损伤和反应堆老化特征。七月底该工作已整理成文并投递给 Acta Materialia 期刊。本文整理归纳期刊投稿时需要准备的材料及注意事项，包括 Manuscript, Cover letter, Suggested Reviewers, Graphical Abstract 等，供自己及朋友们日后参考。
Cover letter
Cover letter 是投稿时与 manuscript 一同发送给 editor 的投稿信。一封内容简洁明了的 cover letter 会让编辑对论文的第一印象加分不少。在信中需简要列出文章的创新点，并且在最后说明全部作者同意投稿，宣称没有利益冲突，该文章没有在其他期刊发表过。
Suggested Reviewers
推荐审稿人一般选择当前投递文章所研究的核心领域内的大牛，通常可以从已发表高水平论文的通讯作者中寻找。本文基于同步辐射 micro-CT 技术研究长时辐照对铝合金材料力学性能的影响，推荐审稿人便可从辐照偏析、铝合金、CT表征分析三个主题方向寻找审稿人，注意科学往往高于技术，切勿太过侧重表征手段。在此列出四条示例：
Prof. Li is an expert in solid mechanics. Using micro computed tomography (CT) and CT-based numerical modelling, he and his group have done excellent work on the structure—property relations of various engineering materials, especially on foams. He is surely suitable and capable of reviewing this manuscript.
Prof. Hutchinson is an expert in materials science. He and his group have done cutting-edge work on the property and deformation mechanisms of Al alloys, especially on precipitate hardening. He is surely suitable and capable of reviewing this manuscript.
Prof. Wang is an expert in nuclear engineering and materials science. He and his group have done excellent work on radiation-induced microstructural evolution and damage of various metal materials. His expertise is directly related to this manuscript. He is surely suitable and capable of reviewing this manuscript.
Prof. Aydogan is an expert in nuclear engineering. She has done excellent work on radiation effects on microstructures and mechanical properties of various metal materials. Her expertise is directly related to this manuscript. She is surely suitable and capable of reviewing this manuscript.
推荐理由需包含：被推荐者是哪个领域的专家，做了哪些突出的工作，以及和本篇文章所研究内容有着怎样的关联性。合理且充分的推荐理由才能对 editor 起到建议作用。
Graphical Abstract
Graphical Abstract 为文章的图形摘要，作者需在极简的图表内高度概括论文中的研究内容和主要创新点，不言自明最为重要，这才能够吸引读者眼球并能让人快速了解您的文章。
Highlights
Highlights 为文章的主要亮点，与 Graphical Abstract 类似，作者需在极简的文字内归纳总结论文的主要亮点。 Elsevier 规范中明确指出 Highlights 的书写规则：三到五条重点；每条重点只包含85个字元；只包含最重要的发现。Acta Materialia 投稿时不再需要附上 Hightlights，但大部分期刊仍然需要，以20年发表的 Powder Technology 举例：
- First in situ characterization of particle breakage in carbonate sands
- Particle shape and intra-granular porosity affects breakage strength
- Fractal dimension of crack networks increases with particle breakage extent
- Cleavage along initial pores leads to crack branching
Reference
以 Acta Materialia 期刊为例，Reference 的书写规范中作者名需以逗号隔开，姓名缩写形如 H. W. Chai，文章标题以逗号结尾，期刊名采用 ISO4 标准期刊缩写，结尾需标注期刊刊号，年份，页码信息。
