网络信息技术为预印本的发展提供了适宜的土壤,同时现有出版体制的弊端促使预印本作为交流系统时效性一种平衡机制的开发和利用。本文以arXiv为例剖析了预印本的运行机制,通过统计数据分析了其在学术信息交流中的作用。文章最后指出预印本的使用与Ingelfinger编辑政策、研究峰值相关。 Web-based information technology has provided a suitable soil for the development of preprints, while the drawbacks of the existing publishing system have led to the development and use of preprints as a balancing mechanism for the timeliness of communication systems. In this paper arXiv is used as an example to analyze the operating mechanism of preprint, and to analyze its role in the exchange of academic information through statistical data. The article concludes by pointing out that the use of preprints is related to the Ingelfinger editorial policy of peak research.
