progress of scientific research depends on academic exchanges。Scientific Research Group、Researchers published a study to the global scientific community and found、Exchange research results，It is an important part of scientific research。Starting from the Royal Society of the British Society in the middle of the 17th century and the French "Scholar Magazine"，Academic exchanges mainly depend on academic journals of peer review，There has been more than 300 years of history。Although the academic communication mode with a journal as the carrier is important，But the exposure of academic communication practice in this mode has received more and more attention。For this，The scientific community has been trying to innovate and change。With the development of science and technology and the change of scientific research paradigm，The scientific community gradually realizes，Open as much as possible、Share，can promote the greater development of science and human society。

Since the end of the 20th century，The academic community initiated a series of open scientific movements designed to overcome traditional scientific disadvantages，Highlighting "freedom、Open、Cooperation、Sharing "concept，The closedness of traditional science and culture has formed a sharp contrast。Especially with the arrival of science 2.0，Pre -printing book、Open peer review、Open Data Storage、With the help of the Internet, innovation promoted by scientific socialization, bet365 best casino games etc.，promoted the diversification of scientific exchanges，Help the birth of the open scientific era。Organization of Economic Cooperation and Development (OECD) in October 2015, "Make Open Science into Reality" pointed out，Science is getting more and more data -driven，Online storage makes obtaining and using scientific research information possible，These accelerated knowledge transfer between different scientific researchers and scientific research fields，The rapid development of "open science"。

The academic exchange system is the release of the scientific research results that supports the scientific community、review evaluation、A mechanism of communication and communication and preservation and use，This mechanism plays a foundation and important role in the scientific community。The development of open science has triggered the change of academic exchange model，Pre -printing book、Scientific Research Social Network、Open Knowledge Base、From the media、Open Data Publishing、Open peer review、Open Publishing and other open academic communication modes and methods and methods continue to appear。These academic communication technology、mode and method，The trend that meets scientific and open development，Adapt to the current technological development trend，I got a lot of scientists、Scientific Research Group、Research Organization、Science Society (Association)、Technology Management Agency、Acknowledge of Fund Organization，It is gradually changing the traditional academic communication mode with the journal as the main body。

　　Support research can repeatable

December 2015，EU launched Foster，Open open scientific training in Europe，Guide stakeholders follow open bet365 best casino games access、Open scientific rules and policies。Foster's definition of open science as，Open science is a scientific practice，Can let others cooperate and make contributions，Among them, you can use research data for free、Experimental records and other research processes，The condition can be reused、Re -allocate and copy research results and their basic data and methods。This shows the relationship between open academic exchanges and repetitive research。In order to better understand the core composition of open science，Foster also clearly defines 4 key terms that constitute open science，Open acquisition、Open Data、Open source software and openness can be repeated research。

First，Open Research Process Support Research Repeated Reality。The sharing of the research process can effectively copy the study。For the author，Sharing research process can represent the authenticity of your research，You can make your research more understandable、Repeated，Attract more peer exchange discussions。In an open scientific environment，Not only the research results can be opened to obtain，The entire research process and peer review will also be stored and managed as open data，and open to the public。"FAIR Data Management Guide to the 2020 Plan Framework" proposed，Research data must be available、accessability、interoperability、Standards for reused。With the opening of the research process，ClinicalTrials.gov、Figshare and other open data warehouses came into being，Open Data Platform Hundred Blossoms。EU under the framework of the "Horizon 2020 Plan"，Provide open scientific cloud services for European researchers and global scientific researchers，Bet365 app download to support cross -border、Disciplinary data storage、Management、Analysis and reuse。Establishing a nationwide data regulatory center (DCC) in the UK to promote the open and transparent of scientific data。The American Open Science Center (COS) builds an open scientific framework (OSF) to provide open data storage services。my country has also made a lot of active exploration in the construction and service of the research data of data on research data，"National Scientific Data Sharing Project" has built more than 50 scientific data centers in many fields，Some colleges and universities (such as Peking University) also launched an open research data platform。

2，Academic exchanges return to scientists to accelerate repetitive research。Open academic exchange environment，The dominance of academic exchanges will return to the scientific community。Scientist group is converting to scientific research groups in the open academic exchange system。For example，Ronald D. Vale formed ASAPBIO in 2016，Promoting the innovation and transparency of academic exchanges in the field of life sciences。The organization thinks，Scientific progress comes from funding from the public，So should be shared without delay。Diversified、Openization、Convenient academic communication method，Accelerated the discovery of research results and communication between scientists。Especially open communication methods represented by pre -print，Make the research results more quickly discovered、​​Repeated。The open review mode of the pre -printed book，It also helps the author and peers faster、Information about repetitive studies in full exchanges，Improving the efficiency of repeated research。At bet365 Play online games the same time，Open academic communication methods can make scientists discover peers faster、Cooperation。Cooperative research on repeated research，Share the results of repeated research to avoid the same research investment，The cost of repetitive research can be reduced。other，Dissemination method、Restrictions on content requirements，Repeated research and negative results are often not accepted by traditional journals。Therefore，Open academic exchanges to become the main position of this type of research。

third，Open scientific development to force the journal to attach importance to research can be repeated。To promote the open scientific process，COS formulated the "Top Guidelines"，Including data transparency、Analysis method is transparent、Research materials transparent、Research Registration、Analysis plan registration、recurability，The higher the level, the higher the repetitive results of the results。Since the release of the document in 2015，About 5,000 academic journals and institutions signed an agreement with COS，Express the willingness to support the transparent and open standards proposed by COS，More than 1,100 academic journals and institutions including Elsevier and Springer Nature are based，Formulate and implement open scientific publishing policies。At the same time，"Nature" and other scientific journals have published related initiatives and guidelines，Discuss the challenges facing the principle of repetitiveness，Enhanced the repeatability of the experiment。American Science Promotion Association (AAAS) and "Science" journal non-profit publishing houses with life science experiment sharing platform bet365 Play online games BIO-Protocol cooperation，It is recommended that the authors published on the "Science" journal published on the BIO-PROTOCOL platform to publish related experimental schemes，Repeatability to improve scientific research results。

　　Pre -printing book: New channels for academic exchanges

Pre -printed academic exchange，It is an important representative of an open academic exchange mode。Since 2016，Academic exchanges based on pre -print books have entered a period of unprecedented prosperity and development。Pre -printed platform Arxiv appeared in 1991，Pre -printed platform SSRN in the field of society and humanities，and the pre -release platform of the Chinese Academy of Sciences in 2016, chinaxiviv, etc.，The influence is increasing，Gradually becoming a new academic communication channel for scientific researchers。Pre -printing this communication while changing the traditional academic communication mode with the journal as the main body，It also provides new positions for repetitive research。Including the use of pre -printing the platform to open sharing research results and research data，Provide fast research for repeated research for peers、Comprehensive experimental information。Release negative results or repeated research on the pre -printing platform，You can conduct direct communication with the original author through the transparent review and open evaluation channels of the pre -printing platform，Notify other colleagues to avoid the same research。

other，Open academic exchanges represented by pre -print，For the monopoly of the academic information of international publishers in my country、Striving for academic words，It also has important significance。Create Open、Transparent、Efficient high -end scientific bet365 best casino games research achievement academic exchange system，It can support repeated research，can also strengthen domestic and international academic exchanges，Promoting the efficient, open sharing, extensive communication and utilization of scientific research information data。
