Recently, Ministry of education and Ministry of science and Technology issued some measures (Trial) on breaking the bad guidance of "only paper" in scientific and technological evaluation. It is hoped that scientific researchers should pay attention to the quality of scientific research rather than the number of scientific research papers. More good academic achievements will be published in domestic journals and SCI journals supremacy will be abandoned. It should be said that these policies were introduced very early. I have written many related articles on the science web, such as "only the number of papers, influencing factors, and the number of citations", and the academic evaluation of three major tumor, November 2018. I have called for "attaching importance to original research and achievements is the only way to break through the Nobel Prize in natural science. In the natural fund review, whether experts will consider the SCI impact factors of journals, 2018-6 also called for the publication of important achievements in domestic journals. Besides, I have also practiced these ideas myself. After returning home, I published academic papers in Journal of non ferrous metals (English version), Journal of metals (English version), and China mechanical engineering. It is worth mentioning that in january2020, as an independent author, I published the academic paper "research progress of deep cold rolling for high performance metal materials" in China mechanical engineering. China mechanical engineering is not searched by SCI at present, but it is a journal of China Society of mechanical engineering, which has a profound influence in the field of mechanical engineering. Therefore, after the paper was published, I specially introduced this paper in wechat circle of friends. If you are interested in the content of this article, please go to the website of China mechanical engineering to download it. This journal is an open source journal. In recent years, the papers can be downloaded freely on the journal web page: http://www.cmemo.org.cn/CN/Y2020/V31/I01/89 .

In the previous years, domestic universities and scientific research institutes attached great importance to SCI database, which led to many strange phenomena in academic circles

(1) Universities attach great importance to the subjects that can publish SCI papers with high impact factors, which leads to uneven development of disciplines. Nowadays, the web pages of universities often introduce the papers published in journals with high impact factors, which are basically in some very small fields, such as catalytic chemistry, new energy materials, cell science, etc. In this way, researchers in other disciplines feel that their field is not as important as they are. Facing these high impact factor writers, many people can only laugh at "you one paper top me 10 papers". There are many subjects in a university. Some disciplines can publish journal papers with high impact factors. However, the subject fields are different. Is it meaningful for them to directly compare SCI influencing factor values, is there some "bull heads are not right for horses"?

(2) Publishing high impact factor journal papers represents academic level cattle, and reward is higher than one. Nowadays, many awards in some universities are directly linked to journal influencing factors, such as how many RMB are more than 30 rewards, how many RMB are more than 20 rewards, and how many RMB are rewarded for more than 10, and the reward base is lower than 10. Such policies lead to some researchers who are not comfortable doing their own field, but follow the wind to do some other fields that can publish high impact factor journals. Such policies, especially for young researchers, have a greater negative impact. The life burden of young researchers is very heavy, many people want to earn more performance to improve their lives and their families. Many young teachers reflect that "survival is the first demand", and it is difficult for them to sit on the bench and do their work in this field.

(3) The introduction of talents in Colleges and universities is directly related to the influence factors of periodicals. Some universities are looking at the influence factors. Nowadays, some colleges and universities have made many policies on introducing teachers, which tend to see the journal influencing factors of the applicant's papers, which leads to the "nobody" of many traditional subjects to recruit. Therefore, in order to meet the basic requirements of the school, these disciplines can only recruit some relative related subjects to recruit qualified teachers. If a college only recruits a few such teachers, it can promote interdisciplinary, which is very beneficial. However, if a college recruits a large number of teachers from other disciplines, over time, the development of this discipline will lose its traditional advantages and eventually become "three different", which is not different. For example, many college materials colleges now look a little like the chemistry college, a little like the physics college, a little like the energy college, and some like the Electronics College, anyway, it is not like the material college.

(4) The price of layout fees of some open source SCI journals has soared, and the number of published papers has soared. Theoretically, publishing papers in open source journals is conducive to academic development. However, there is a strange phenomenon in publishing houses. Some open source journals may not charge the layout fees at first. However, once they are retrieved by SCI database, they will become fees. If the influence factor increases, the price of layout fee will continue to rise. It is especially funny that before some journals are retrieved by SCI, there may be no papers published by Chinese researchers. Once they are retrieved by SCI, the number of papers from China will increase dramatically. Once they were kicked out of the SCI database, no one contributed. It seems that SCI retrieval has become the "value standard" of the paper.



Although SCI database is a retrieval tool, it is convenient for scientific researchers to track the development of disciplines, but because domestic researchers attach great importance to SCI retrieval, its negative impact on Chinese academic circle has exceeded positive impact, which has brought heavy burden to researchers, and it is time to abandon it. Besides, the era of SCI papers quantity heroes is the time to open the core standards for the content and quality evaluation of papers.

Now what should we do?

(1) Based on the development of disciplines, the research object is aimed at the key scientific and engineering problems in the field. Because we were happy to publish papers in SCI journals in the past few years, many people were willing to do some "short, flat, fast" work. In this context, those who have solved major problems on the ground and achieved "less and slower" results face the possibility of being eliminated by "bad currency". In the future, we will implement the representative work system. Those important scientific and engineering problems solved will become their beautiful "representative works", and can throw away the "papers" which are not painful enough. Therefore, researchers can "concentrate on solving important problems", rather than trying to make "quantitative objective" papers to constantly dig into data and piece together general papers. Obviously, after some years of normal development, the development of various disciplines will be more balanced.

(2) We should pay more attention to the mainstream journals in this field and their development, and pursue journals that are not highly influential in the field, but those published in this field. For a long time, in my research group, the paper level is not judged by the influence factors of journals. For example, the impact factor of metal mate trans a journal is only about 1.8, but I am willing to publish the best achievements in the research group in this journal, and I have published 1-2 papers in the journal every year in recent years. As for the journals with higher influence factors than this one, there are still many, but the importance in my heart is in the back. As a researcher, we should strive to publish the best results in influential journals, not only to simply see the high and low impact factors of journals, but also not to publish their work to journals not in the field, even if the impact factors of these journals are far higher than those in the field.

(3) We should publish as many excellent research results as possible in domestic academic journals and strive to make them representative works. In this measure, one third of the representative works in the future are required to be published in domestic academic journals, so we will be more willing to contribute to important academic journals in China. Since it is your representative work, it is necessary to publish the best results in these journals. On the one hand, this will promote the development of the quality of domestic academic journals, on the other hand, it can make more scientific intellectual property rights reserved in domestic academic journals. Nowadays, the state attaches more and more importance to the protection of intellectual property, and it is necessary to keep the intellectual property rights of our best achievements in the domestic excellent academic journals. Think about how IEEE Journal treated Huawei, our technology enterprise last year. If other technology enterprises face the same problems in the future, how can we deal with them? Now we publish the best achievements in domestic journals, especially in Chinese journals in our native language. The quality of the papers in these journals will be greatly improved, which is of great significance for the domestic scientific and technological workers and engineers to consult, understand and transform the most advanced scientific research results.

Remember the new year's message to China Mechanical Engineering two years ago, "technology is changing day by day, creating new meaning and meaning. Mechanical intelligence and wisdom, engineering is the top priority. " We should be down-to-earth, calm and attentive to scientific research, and strive to make influential scientific research results.
