Nowadays, h-index is considered as an important factor to assess the productivity and citation impact of researchers’ publications. Indeed, Jorge E. Hirsch, a physicist at University of California San Diego, developed and suggested h-index in 2005. At the time, h-index could present a score, which successfully integrated the number of articles and citations for a researcher. Thus, it could simultaneously assess the quality and quantity of a researcher’s total publications. It was also simple and easy to understand. Accordingly, h-index received much attention all around the world and became popular very soon. So that, currently in many scientific societies, it is considered as a factor to compare the scientific impact and credit of researchers. However, h-index has received many criticisms since its introduction. Here, I want to mention some of its defects and weaknesses, as a factor assessing the scientific impact and credit of researchers, from my point of view. However, these defects also has been discussed previously in different manners. Finally, this letter is going to conclude that nowadays, we need a more comprehensive ranking-factor (as an appropriate alternative for h-index) that keeps the advantages of h-index, while lacks its weaknesses.

如今，h指数被认为是评估研究人员出版物生产力和引文影响的重要因素。事实上，加州大学圣地亚哥分校的物理学家 Jorge E. Hirsch在 2005 年开发并提出了h- index。当时，h- index 可以呈现一个分数，它成功地整合了研究人​​员的文章数量和引用次数。因此，它可以同时评估研究人员总出版物的质量和数量。它也很简单易懂。因此，h-index 在世界范围内备受关注，并很快流行起来。因此，目前在许多科学团体中，它被视为比较研究人员的科学影响和信誉的一个因素。然而，h指数自推出以来就受到了很多批评。在这里，我想提一下它的一些缺陷和弱点，作为评估研究人员的科学影响和信誉的一个因素，从我的角度来看。然而，这些缺陷之前也以不同的方式讨论过。最后，这封信是要得出结论，现在，我们需要一个更综合排名因素（作为一个合适的替代h指数，保持优势）^ h -index，而缺少它的弱点。
