安徽合肥遥测地震台网数字资料与模拟资料的综合对比

在安徽省数字观测系统将逐步取代模拟观测系统的过渡时期，对安徽霍山地区3个台站老皇寺、豹子崖、石家河进行了震级更正，对记录到的数字观测资料和模拟观测资料分别进行了对比。结果表明，经过A／D后的数字记录震级目前可以和其他数字台一起参与震级平均，数字记录结果和安徽省地震局编目结果偏差基本上未超过允许范围，速度震级和仿真位移震级之间的偏差在0．2以内。

Comprehensive Comparison of Digital Data with Analog Data of Hefei Renote Seismic Network in Anhui Province

While the digital observation system will take place of analog system in Anhui,we compared the digital data with the analog data after had ajusted the magnitudes of Laohuangsi,Baoziya and shijiahe station.The results show that the magnitudes by trasformation of A/D can average with the digital data of other stations,processing precision of digital data is not beyond the limit,and the deviation between the velocity magnitude and the simulate displacement magnitude is within 0.2.
