摘要
介绍了广义相对论在时频计量中的应用的重要性和当前研究现状 ,评述了该领域的几个主要问题 :原 (固有 ,本征 )时与坐标时的关系 ;不同坐标时之间的转换 ;各种不同方式的时间比对及各种不同方式的频率比对 ,给出了有关研究的最新结果。最后 ,简要地讨论了该领域需要关注的几个问题。
The significance and research status on the application of general relativity to the time frequency metrology are introduced,and the main subjects in this field such as the relationship between proper time and coordinate time,the transformation between different coordinate times,the different means of time comparisons,and the different means of frequency comparisons,are reviewed with the updated results presented. At the end the issues in this field,which need to be paid attention to,are discussed briefly.
