随着社会经济和科学技术的高速发展,对时间频率传递和同步的需求越来越高,特别是在基础科学、深空探测、现代高科技装备和系统中,时间的精确性及稳定性至关重要。基于光纤的时间频率传递成为未来高精度地面时间同步网络的主要发展趋势。该研究以INSPEC数据库为数据源,采用专业数据分析工具Thomson Data Analyzer(TDA)对光纤时间频率传递研究论文进行数据挖掘和定量分析,探讨该领域的研究现状、主要研究力量、研究热点及发展趋势,以期为时间频率科研工作者、决策者以及我国时间频率系统的发展、创新提供参考。
With the rapid development of socio-economy and science and technology, there is an increasing demand for time-frequency transmission and synchronization. In particular, in the basic sciences, deep space exploration, modern high-tech equipment and systems, the accuracy and stability of time Important. Time-frequency transmission based on optical fiber becomes the main trend of future high-precision terrestrial time synchronization network. The research takes INSPEC database as the data source, uses the professional data analysis tool Thomson Data Analyzer (TDA) to do the data mining and quantitative analysis on the research papers of fiber time and frequency transmission, and discusses the research status, main research strength, research hot spots and development trend in this field , In order to provide a reference for the development and innovation of time-frequency research workers, policy-makers and China’s time-frequency system.
