无意间发现西北大学数学学院Zhu-Minghui、Han-Di共同发表并以Han-Di为通讯作者的文章 Zhu, Minhui, and Di Han. "Retracted Article: On the fourth power mean of the two- term exponential sums." Journal of Inequalities and Applications 2014.1 (2014): 1. 几乎全文抄袭了西北大学数学学院Zhang-Han、张文鹏共同发表并以张文鹏为通讯作者已经发表的文章 Zhang, Han, and Wenpeng Zhang. "On the fourth power mean of the two-term exponential sums." The Scientific World Journal 2014 (2014). 我们可以非常明显的发现,这两篇文章的主要结果和叙述用词,几乎没有差别,而且在投稿时间上也非常近,都是2014年左右。让人更加无法理喻的是,Zhu-Minghui、Han-Di公然抄袭的文章,最近到了2016年,还有人在公开引用:文章:杜晓英. 两项指数和及两项特征和的混合均值[J]. 数学学报, 59(3): 309-316.的参考文献: [14] Zhu M. H., Han D., On the fourth power mean of the two-term exponential sums, J. Inequalities App., 2014, 116: 7. 西北大学Zhu-Minghui、Han-Di,既然可以几乎毫无顾忌的全部抄袭已经发表的文章,那么我们查一查他们的发表记录,发现上大部分发表的文章,都是通过花钱灌水的方式发表的,这些杂志基本上以盈利为目的,没有正规严格的审稿流程。而中国大陆仍然有一部分人喜欢在这些杂志上发表垃圾论文进行灌水,进而蒙骗他人,攫取大量的项目经费,各种评审奖项。 收费SCI杂志及价格 Journal of Inequalities and Applications:一篇论文:1140美元/930欧元; International Journal of Applied Mathematics & Statistics:快速审稿:300欧元/篇;接受发表:30欧元/页; Advances in Difference Equations: 一篇论文:980美元/800欧元; Han-Di、张文鹏等人5篇花钱灌水的论文(不含上述抄袭被杂志撤稿的论文): Wang, Weiqiong; Han, Di, An identity involving certain Hardy sums and Ramanujan's sum.

(English summary) J. Number Theory 129 (2009), no. 4, 948–963. 11L26 (11L40) 评论者明确指出: But a considerable number of errors have been overlooked by the authors. They give, for example, a false proof of the bound (Lemma 2.3), which is of central importance for some of their main results. A proof of this bound is, however, not required, since the bound is contained in a special case of their Lemma 3.2, the proof of which is omitted from the paper on the grounds that it follows easily from a lemma proved in work of Zhang, Y. Yi and X. L. He [J. Number Theory 84 (2000), no. 2, 199–213; MR1795790]. Other (more minor) errors and superfluities abound. The main term in the asymptotic formula given by Theorem 3.1 is too small by a factor of π/8. 其二:MR3079817 Reviewed Xu, ZheFeng(PRC-NU) On the difference between an integer and its m-th power mod n. (English summary) Sci. China Math. 56 (2013), no. 8, 1597–1606. 11N69 (11L05 11L07) 评论者明确指出: In Theorem 1.6 of the paper the author claims, in cases where n=pα for some prime p and some integer α>1, an estimate for the sum N(n,m;t;k). However the stated estimate is not correct (it is easily seen to be false when, for example, one has t1=t2=1/2, n=p2, m=φ(n), k=1 and p both prime and sufficiently large). The corresponding error in the author's proof occurs towards the end of the proof of Lemma 2.9, where there is an obviously incorrect deduction made from the exponential sum estimates of T. Cochrane and Z. Y. Zheng [Asian J. Math. 4 (2000), no. 4, 757–773; MR1870657] that are stated in Lemma 2.2 (where, incidentally, the case α=1 is nugatory). Reviewed by Nigel Watt(XYS20160704)
