注意：这10本期刊受到SCI官方警告，今年不出影响因子！

2021年6月30日发布的JCR对21种期刊进行了警告(没给影响因子)或表示关切为保证期刊遴选和报告的公证公允，今年的《期刊引证报告》警告了10种期刊。科睿唯安坚持监测和淘汰存在异常引用现象的期刊，包括存在过度自引和互引迹象的期刊。科睿唯安在2020年对计算期刊自引对报告指标影响的方法和参数进行了更新，以便更好地反映学科规范。JCR 对期刊提出警告不等同于相关期刊从 Web of Science Core Collection 中被剔除。此外，今年 JCR 还发布了针对11种期刊的“编辑关切”，这些期刊中有一篇或多篇出版内容对期刊影响因子分子有不正常的高值贡献，并且期刊的引文不成比例地集中在这些期刊影响因子分子上。科睿唯安将继续审查这类内容，对其进行附加检查，防止期刊影响因子失真。警告的10种期刊如下，这些期刊没有给影响因子：JCR TitleFull TitleTypeARCH LATINOAM NU-TRArchivos Latinoamericanos de NutricionStackingHELL J CARDIOLHellenic Journal of CardiologySelfINT J ENGINE RESInternational Journal of Engine ResearchSelfJ BIOMOL STRUCT DYNJournal of Biomolecular Structure and DynamicsSelfJ ENHANC HEAT TRANSFJournal of Enhanced Heat TransferSelfJ FAM ECON ISSJournal of Family and Economic IssuesSelfJ INTELL FUZZY SYSTJournal of Intelligent & Fuzzy SystemsStackingLIQ CRYSTLiquid CrystalsSelfMATER EXPRESSMaterials ExpressStackingMECH BASED DES STRUCMechanics Based Design of Structures and MachinesSelf原文详见：http://jcr.help.clarivate.com/Content/title-suppressions.htm表示关切的11种期刊如下：Journal TitleJIF NumeratorHighest Single-Paper Journal Self-CitationsTotal Journal Self-CitationsArteriosclerosis Thrombosis and Vascular Biology 3974 189 582Artificial Organs 889 124 260British Journal of Biomedical Science 268 50 77Clinical and Translational Allergy 546 61 86European Journal of Epidemiology 1677 180 209European Journal of Histochemistry 255 69 80Histochemistry and Cell Biology 792 58 92International Journal of Cardiovascular Imaging 1021 109 186Journal of Allergy and Clinical Immunology-In Practice 3895 147 664Journal of Neurosurgical Anesthesiology 358 91 117Journal of Raman Spectroscopy 1273 200 320原文详见：http://jcr.help.clarivate.com/Content/editorial-expression-concern.htm以上期刊中，没有中国大陆期刊。
