原子钟权重

原子钟权重的大小是国际原子时归算时的参数和衡量原子钟长期性能水平的标志。根据原子钟的性能确定其权重，可以充分发挥性能优秀的原子钟优势。BIPM原子钟权重计算周期为一个月，每月初公布上月相关儒略日对应权重的计算结果。NTSC通过数据字典匹配提取NTSC原子钟权重数据。

The weight magnitude of an atomic clock serves as both a parameter for the reduction of International Atomic Time (TAI) and an indicator for assessing the long-term performance of atomic clocks. Determining the weight of an atomic clock based on its performance can fully leverage the advantages of high-performance atomic clocks. BIPM calculates atomic clock weights on a monthly cycle, and releases the calculated weight results corresponding to the Julian dates of the previous month at the beginning of each month. NTSC extracts its atomic clock weight data via data dictionary matching.
