关于paper, 总是有比没有强。发paper有以下几种：第一，你已经发表了paper, 这样在你的简历你请把Citation写出来比如Additive temporal colored noise induced Eckhaus instabilityin complex Ginzburg-Landau equation systemAuthor: WANG Xin, TIAN Xu, WANG Hong-li, OUYANG Qi and LI HaoChinese Physics Letters Vol. 21, No. 12, pp2365-2368.第二，你写好了paper, 也已经提交了。人家也审完了，决定发表。但是还没真的发表出来这样在题目和作者后面写to be published (on 杂志名)第三，你写好了paper, 也已经提交了。人家没审完，你还不知道发表不发表这时候写submitted (to 杂志名)或者under review第四，你写好了paper, 还没提交。写to be submitted ( to 杂志名)第五，你还没写好paper, 写in preparation。甚至你还没写paper, 只要你觉得你在这个领域的工作可以总结了，就这么写就成了。没人管你什么时候写完的。很多人一大串的publication list里就有好几个preparation现在看出来这个等级了吧。还有，第一种情况也是分等级的，人家会看你发表在什么档次的杂志上。很多人问我第一第二作者的问题。我想类比一下上面的等级就明白了吧。论文合集或年鉴上也算，同上，有总比没有强。
至少第二作者，具体视各个学校的规定而定。像我们学校只承认第一作者或者通讯作者的paper。一般SCI期刊的文章第二作者也没用——要求核心期刊paper毕业，SCI期刊第二作者也不能毕业。
超级厉害的！很多博士发表一篇SCI论文才能毕业。而一个本科生能发表SCI，基本保研肯定没有问题的。
应该说还是挺厉害的，不过也要具体问题具体分析：1、同样是省级期刊，差别也会很大。有的就比较垃圾，有的是质量比较高的，比如一些学报。2、同样是省级期刊，如果所发表的省级期刊知网有收录，页码在200页内，且有影响因子，一般来说对后续的留学、保研等都是有帮助的。
paper 英[ˈpeɪpə(r)] 美[ˈpeɪpər] n. 纸; 论文; 文件; 文章; vt. 贴纸; vt. 包装，用纸覆盖; 贴壁纸; 提供纸张; [俚语] 提供免费入场券; [例句]He wrote his name down on a piece of paper for me他把他的名字写在一张纸上交给我。[其他] 第三人称单数：papers 复数：papers 现在分词：papering过去式：papered 过去分词：papered
单词“paper”是美式英语；在英式英语中，我们叫“essay”。他们两都一般与本科学位有关系。单词“thesis”一般与博士学生的最后那篇写作（通常就是指毕业论文）有关，而“dissertation”是指硕士学位的啦。Essay 一般指几千字级别的小论文/课程论文，通常只有文献综述和对文献的批判分析，可以没有独立的数据和实证（即便有也是简化的）。可以没有完整的数据或文献，也可以只针对一些著作或观点谈谈自己的想法和见解，可以是批判性的，也可以是赞同的。Essay 通常会比较常运用于美式英语中。在英式英语中，人们则会习惯于把 essay 当做本科时期的论文，这也是美式英语和英式英语的不同吧。不过，essay 相对其他两个 paper 和 dissertation 来说，它的用法是广泛的，它不仅仅涵盖了论文这一层面的意思，同时，它这个词在牛津词典里的含义有（尤指学生写的作为课程作业的）短文，论说文，小品文，散文。单词 thesis 和 dissertation，他们一般是指为了获得学位或呈现作者的研究和发现的文章。在某些情况下，thesis 或同类词是用于本科或硕士课程的一部分，然而 dissertation 通常适用于博士学位。有时候，又是相反的。graduate thesis 有时用来指硕士论文和博士论文。而在不同的国家，应用也不相同在英国英语中，本科和硕士论文叫做 dissertation， 博士论文用 thesis。在美国英语中，本科和硕士论文用 thesis，博士论文用 dissertation。
论文，一般都是一个意思的。
paper、thesis、dissertation的区别为：
一、指代不同
1、paper：纸张。
2、thesis：论文。
3、dissertation：学位论文。
二、侧重点不同
1、paper：文章篇幅比较短，一般指几千字级别。
2、thesis：一般是比较长的写作，一般指的是学位论文。
3、dissertation：一般是1-2万字级别的文章。
三、引证用法不同
1、paper：paper正式用词，多指在学术刊物上发表或在学术会议上宣读的专题论文，也指高等学校的学期论文，或学校里的作文练习。
2、thesis：既可指毕业论文、学位论文，又可指一般的为阐述学术观点而写的论文。
3、dissertation：书面语用词，指独立研究后所写的较为详细的专题文章；也可指学位论文。

当然算论文，是“没有发表的论文”。 如果自己觉得质量还可以，当然可以放在简历里，作为证明科研能力的一个参考。不过要当心自己的成果被剽窃啦。
paper是论文的意思。
论文一般由名称、作者、摘要、关键词、正文、参考文献和附录等部分组成，其中部分组成（例如附录）可有可无。
paper，英[ˈpeɪpə(r)]；美[ˈpeɪpər]有名词、动词、形容词，作名词时翻译为“纸；论文；文件；报纸”，作及物动词时翻译为“用纸糊；用纸包装”，作不及物动词时翻译为“贴糊墙纸；发交通违章传票”，作形容词时翻译为“纸做的”。

靠！那不止是厉害，那是厉害PLUS了。一般的大学教授能发表一篇SCI都不容易，很多博士发表一篇SCI论文才能毕业。而一个本科生能发表SCI，基本是大神级别了。保研肯定没有问题的。但是大多数人还是洗洗睡吧，没有这个学霸基因。如果你想发表SCI期刊，你可以去淘淘论文网上学习下SCI论文发表知识。
参加国家级学术会议并发表了会议论文，严格地说，只能算是宣读了论文。一般宣读后的论文都会结集出版或在期刊上发表，只有在核心期刊发表才能算。

1.如果本科毕业后找工作，这篇sci文章是一块很好的敲门砖2.对于保研算是一项很大的加分项，对于找一个好的导师也有帮助，但是门也喜欢研究撑过多的学生3.对于拿奖学金有帮助。如果本科时期能发一篇sci文章，拿一等奖几乎不在话下4.目前各大一流城市落户都需要本人有专利或者顶学术成果，这篇sci对于落户大城市也有一定的帮助。供参考。
