１ＳＺＺ－Ⅱ型数字钟研制课题的提出１．１高精度、高稳定的数字钟，是台站高质量运行的重要保证无论是人工值守台还是遥测地震台网测定地震基本参数时，均需同时记有精确的时间标记，便于分析人员准确判读地震事件的到时，完成地震基本参数的测定。如果数字钟钟差严重超...
1SZZ-Ⅱ type digital clock research project proposed 1.1 high-precision, high stability of the digital clock is an important guarantee for the station high-quality operation Whether it is manual value of the earth station or telemetry seismic network to determine the basic parameters of the earthquake, both at the same time The accurate time stamps are recorded so that analysts can complete the determination of the basic parameters of the earthquake by accurately reading the time of the earthquake event. If the digital clock worse than the super ...
