论文部分内容阅读
利用AMLC对《重庆大学学报》自2010年6月至2011年5月收到的163篇环境类论文进行检测，发现文字重复率≥5％的稿件有52篇，文字相似比集中在5％-40％。逐篇分析发现：有29篇存在学术不端行为，主要表现为引而不注和拆分论文；文字相似比较高部分通常为引言和结果分析与讨论，而环境工程应用案例因其特殊性而被抄袭的概率较小。指出AMLC检测的局限及特点，并有针对性地给出了编辑可采取的对策。“,”Academic Misconduct Literature Check （AMLC） is used to check 163 environmental papers contributed to Journal of Chongqing University from 1 June 2010 to 31 May 2011. It is found that 52 papers repeat sentences or paragraphs of other articles to some extent with a repetition ratio ranging from 5% -40%. By analyzing the results one by one, it is found that 29 papers have academic misconducts, mainly including plagiarism and paper separation; high repetition parts appear usually in sections of introduction and results analysis and discussion, while environmental application cases are not much likely to be plagiarized due to their uniqueness. AMLC＇s limitations are also analyzed, and measures to improve AMLC＇s weakness are suggested.
