9、言不规范（缺少层次和条理、口语化、语法错误多）抄袭现象严重（引用无标注、间接引用）参考文献引用不规范（标注错误、格式错误、代表性）SCI(Science Citation Index)是美国科学情报研究所（ISI）出版的一部世界最著名的期刊文献检索工具。被SCI收录的论文称为SCI论文。SCI收录全世界出版的数、理、化、农、林、医、生命科学、天文、地理、环境、材料、工程技术等自然科学各学科的英文核心期刊。SCI源期刊分为SCI和SCI-E 2类。SCI是指来源期刊为3500种左右的SCI核心区期刊，SCI-E的全称是SCI-Expanded，是SCI扩展版。2013年SCI扩展版期刊9338种
10、。ISI通过严格的选刊标准和评估程序挑选刊源，而且每年略有增减，从而做到SCI收录的文献能全面覆盖全世界最重要和最有影响力的研究成果。SCI是科研评价的重要依据。ISI每年出版JCR(Journal Citation Reports)。JCR对SCI收录的期刊之间引用和被引用数据进行统计，报道每种期刊的Impact Factor、Total Cites、Cited Articles、Cited Half-life、Immediacy Index等指数。一种期刊的影响因子，指的是该刊前2年发表的文献在当前年的平均被引用次数。2013年所有SCI源期刊引用该刊2011年和2012年论文总数2013
11、年某刊IF=该刊2011年和2012年刊载论文总篇数（article+review)分子指被引的所有论文，分母仅包含article和review 一种刊物的影响因子越高，即其刊载的文献被引用率越高，说明这些文献报道的研究成果影响力大。影响因子是衡量学术期刊学术水平的主要指标。影响因子不是衡量期刊学术水平的唯一指标。不同学科影响面不一样，有些期刊影响因子不高，但在学科内部有较大的影响力。ISI将各学科SCI期刊分为4个区。I区是各学科最有影响力的期刊；而IV区为相对最缺少影响力的期刊。Scientific PapersIn the past ten years,about 200 papers
