原子钟速率
收藏资源简介:
国际权度局BIPM原子钟速率计算周期为一个月,每月初公布上月相关儒略日对应的速率计算结果,单位为ns/天。其中,钟的序号不同数字对应了不同的钟的类型,其中35-表示铯原子钟、4x-表示氢原子钟,这两种占据了钟类型的绝大多数,此外还有其他的钟类型。NTSC通过数据字典匹配提取NTSC原子钟速率数据。
The International Bureau of Weights and Measures (BIPM) adopts a one-month cycle for atomic clock rate calculation. It publishes the rate calculation results corresponding to the Julian days of the preceding month at the beginning of each month, with the unit of nanoseconds per day (ns/day). Distinct clock types are identified by different numeric prefixes in the clock serial numbers: specifically, the prefix "35-" indicates cesium atomic clocks, while "4x-" represents hydrogen masers. These two categories account for the vast majority of all clock types, with other types also existing. NTSC extracts its atomic clock rate data via data dictionary matching.
