SCI论文要求一般的投稿要求与国内一些期刊类似，但有些地方还是有些出入。二当家最近在投稿中也遇到过不懂的地方，查找了一些资料，顺便总结一下，希望对科研筒子们有所帮助。
投稿信（Cover Letter）一般为简述所投稿件的核心内容、主要发现和意义，拟投期刊，对稿件处理有无特殊要求等（如“not to review” list）。另外，请附上主要作者的中文姓名、通讯地址、电话、传真和e-mail地址。此外有的杂志要求推荐几位审稿人及其联系方式，以及谁已经阅读过该文（最好写专业领域类的知名专家、大牛）。
一般来说，杂志通常要求说明你论文研究的意义，以及与这个杂志的相关性，另外还有的可能要写明你没有一搞多投等，此外临床实验要求写明符合伦理学要求。当然各个杂志的具体要求是不一样的，在杂志的guide for authors一般会有要求。如果没有具体的要求，大家可按照通用要求处理。
