| 摘 要： | 分析了引起微波时间传递系统时延变化的原因和单向及双向时间传递比对精度；分析表明，根据微波双向时间比对的长期测量数据可对搬钟实验得到的时延值进行修正，采用该修正结果可减小单向时间比对的误差。

| Abstract: | The cause of the fluctuation of time delay for the microwave time transfer system, and the precision of one-way and two-way time transfer are analyzed. The analyses show that the time delay determined via clock transporting for the microwave time transfer system can be corrected by using the long-term data of microwave two-way time transfer, and the corrected time delay can be applied to the one-way time comparison to minimize the comparison error. |
