作者：美捷登Kristen 在學術(shù)論文投稿過程中，許多作者一門心思打磨數(shù)據(jù)、雕琢措辭，卻往往忽略了一個隱藏的“攔路虎”——文章的重復率。事實上，許多期刊對重復率的要求嚴苛得堪比論文評審人犀利的眼神，稍有不慎，稿件就可能被“溫柔”地退回修改，甚至直接被判處“拒稿徒刑”，讓作者的SCI夢在投稿系統(tǒng)里戛然而止。
為了讓各位同行少走彎路、少受打擊，美捷登老司機結(jié)合二十年投稿經(jīng)驗，總結(jié)了幾種常見的“重復率踩雷”場景，希望能幫大家避開這些坑，順利闖關(guān)，實現(xiàn)論文發(fā)表的美好愿望！
第一類：投稿后被退回要求降低重復率 許多期刊在收到稿件后，會使用查重軟件（如iThenticate）對稿件進行重復率檢測。如果重復率超過期刊規(guī)定的閾值，稿件將被退回并要求作者修改。以下是一些常見的例子： - Journal of Advanced Research (IF: 11.4)
該期刊要求稿件的重復率低于25%。一位作者在投稿后收到退回信，信中明確指出：
"CrossRef check powered by the iThenticate software resulted in 32% similarity between your manuscript and previously published literature. Please cut it below 25%." - Annals of Hepatology (IF: 3.7)
該期刊在退回信中提到：
"Our system's similarity analysis tool has flagged a significant percentage of similarity between your manuscript and other texts in the scientific literature. We kindly request that you review your work and make the necessary revisions to address this concern."
- Frontiers in Bioscience-Landmark (IF: 3.3)
該期刊要求研究論文的重復率控制在25%以內(nèi)。一位作者收到退回信：
"After checking, I found that the manuscript has a high duplication rate. According to the publishing regulations of our journal, the duplication rate of research papers must be controlled within 25%. Please reduce the duplication rate to below 25%."
- PeerJ (IF: 2.3)
該期刊在退回信中明確指出：
"We noticed that your manuscript contains an unacceptable level of apparently re-used text. We are unable to consider your submission unless you address this issue and submit a new version of the manuscript."
- Annals of Dermatology (IF: 1.6)
該期刊要求重復率低于25%。一位作者收到退回信：
"Similarity tests showed a similarity of 27% excluding references. Please revise manuscript to 25% or less."
- Clinical and Experimental Obstetrics & Gynecology (IF: 0.4)
該期刊不僅要求整體重復率低于25%，還要求單篇參考文獻的重復率低于5%。退回信中寫道：
"Please ensure that the article's repetition rate is less than 25% and the repetition rate between the manuscript and any reference is less than 5%. This is not acceptable for high repetition."
第二類：因重復率過高被直接拒稿 如果稿件的重復率過高，期刊可能會直接拒稿，甚至指出存在抄襲行為。以下是一些典型案例：
- Biofactors (IF: 5)
一位作者收到拒稿信：
"A routine check with the software iThenticate has indicated 41% similarity of this paper with published material. This value highly exceeds the limits accepted by the Journal and thus your manuscript has been denied publication."
- Molecules and Cells (IF: 3.7)
盡管該期刊對稿件表示感興趣，編輯在拒稿信中寫道：
"Although your work is of potential interest to the readers of Molecules and Cells, the similarity index to already published articles turned out to be rather high. This may be accidental, but the issue of plagiarism needs to be fully addressed prior to consideration for publication."
- Saudi Pharmaceutical Journal (IF: 3)
拒稿信指出：
"Your manuscript shows an unacceptable level of overlap with prior publications. There are numerous complete sentences and paragraphs that are virtually unchanged. In the present form, the originality of the study cannot be assessed."
- European Journal of Oncology Nursing (IF: 2.7)
拒稿信中提到：
"Your paper has a very high similarity index of 40%. After careful consideration at the editorial board, we are sorry to advise you that we will not be able to accept this paper for publication."
- Journal of Vascular and Interventional Radiology (IF: 2.6)
拒稿信明確指出：
"This submission includes a substantial portion of text copied from other sources. Authors are advised to revise instances of plagiarism prior to submitting to an alternative journal, as plagiarism is considered a major breach of publishing ethics."
- Journal of Applied Ichthyology (IF: 0.7)
拒稿信中提到：
"Your similarity index with published work is as high as 56% (!!!) indication that on average every second word is copy-pasted from published journal articles. This does not only create significant copyright issues, it also constitutes a serious kind of scientific misconduct."
第三類：修回時要求降低重復率 即使稿件進入修回階段，期刊仍可能要求進一步降低重復率。以下是一些例子：
- Saudi Medical Journal (IF: 1.7)
修回信中要求：
"Your similarity check results based on iThenticate was 36%. Please note that similarity should not be higher than 10% to avoid textual plagiarism. This is Journal Policy."
- Neurosciences (IF: 1.2)
修回信中強調(diào)：
"Please note that the journal is very strict with textual plagiarism. Any statement found similar to previous study should be rewritten in own words and reference. Your similarity check results based on iThenticate was 23%. Please note that similarity should not be higher than 10%."
投稿前的建議 為了避免因重復率問題導致稿件被退回或拒稿，建議作者在投稿前采取以下措施：
- 使用查重工具：在投稿前，使用iThenticate等專業(yè)查重工具檢測稿件的重復率，確保文章的原創(chuàng)性。
- 合理引用：引用他人研究成果時，要準確標注來源，避免大段直接復制，盡量用自己的話表達。
- 避免重復表述：盡量減少與已發(fā)表文獻的重疊部分，尤其是常見的研究方法和理論框架，重新表述或補充新的內(nèi)容。
結(jié)語 重復率問題是學術(shù)投稿中不可忽視的一環(huán)。許多學術(shù)期刊對重復率有嚴格的要求，作者們在投稿前必須仔細檢查文稿，確保重復率符合雜志的要求。采取合適的措施降低重復率，不僅能提高論文的質(zhì)量，還能避免因為重復率過高而遭遇拒稿或修改的麻煩。
